Frontier Computing\ \ Y Combinator LogoS2026\ \ • Active • 1 employees • London

Frontier is first to grow biological brains at scale, serving biological neural nets with substrate-level colocation of memory and compute, enabling highly cost effective training of large parameter count models.

While academia has traditionally been limited to ~1M neurons in vitro, Frontier has built a pathway to scale to 100M+ neurons by circumventing traditional scaling challenges in biological culture, demonstrating this strategy's functionality by training a biological brain using this scaling primitive to play Frogger.

Frontier is now growing exascale compute clusters to produce substrates capable of long-horizon language reasoning while operating at much higher sample efficiencies than traditional architectures, and collocating memory with compute to enable significantly larger parameter counts than would be tractable for training within traditional compute clusters.

Sentient OS\ \ Y Combinator LogoF2026\ \ • Active • 2 employees • San Francisco

Nobody's built truly proactive AI, because it requires running inference on your entire life. In the cloud, that's insanely expensive and a privacy nightmare. But not on your own chip.

Every night, Sentient's on-device LLM wakes your Mac and understands what's new in your life (email, messages, files, Granola transcripts...), entirely locally, and distills it into a knowledge base.

You wake up to your work already prepared: the reply you forgot, drafted from your own context; the subscription you never use renewing tomorrow, caught; the report you promised in the group chat, ready to send. Everything is one click from firing through computer use, and nothing fires until you click.

Or click your Mac notch anytime and say "finish this for me." Sidekick takes over the thing you were doing with its own cursor while you move on.

On-device inference at this scale was supposed to be impossible: devices too slow, and models too dumb. So we built the stack ourselves: a custom LiteRT-LM fork (KV-cache reuse, speculative decoding, custom k-quants) that runs nightly on 8 GB Macs. The user's hardware does ~90% of the compute, and their own ChatGPT or Claude subscription does the rest, so our marginal cost is ~$0, and our servers store nothing.

We soft-launched late July with one Reddit post: top of r/macapps, 2,000+ users in 48 hours, $0 marketing. Free and open source for consumers; the same engine on the work stack (Slack, Granola, Linear, Notion) becomes the enterprise business.

Waybill\ \ Y Combinator LogoS2026\ \ • Active • 5 employees • Gurugram, Haryana, India

Hardware teams burn weeks on procurement. An engineer needs a part. Someone emails five distributors, chases quotes, gets an approval, wires the money, tracks a shipment across three carriers, clears customs, and then nobody knows where the box is or what's actually on the shelf.

Waybill runs that entire loop. Send us a part, a spec, or a BOM. We source it, pull quotes, route approvals, pay the supplier, handle freight and customs, track it to your dock, and keep your stock count updated.

Take your supply chain for granted.

Built by a team that's seen it at LAT Aerospace and WareIQ (YC S20).

Dream\ \ Y Combinator LogoS2026\ \ • Active • 2 employees • San Francisco

Dream makes pocket-sized, battery-powered AI cameras that catch damage teams miss. Car dealerships, equipment rental companies, fleets, and more move expensive assets in and out all day, and undocumented damage is a costly leak.

Dream cameras are simple to set up and work automatically. Each vehicle or machine that passes is photographed from every angle, identified, and reconstructed into a 3D condition record. On return or intake, Dream instantly flags new dents, scrapes, and changes your team might miss, giving one source of truth for every asset's condition over time.

Ryland worked at X/xAI and built aerial damage-detection vision at Vexcel Imaging. Alexander worked at AWS and trained edge-camera models deployed in the wild across Africa and India to detect poachers.

Familiar\ \ Y Combinator LogoS2026\ \ • Active • 8 employees • Toronto, ON, Canada

Audio-visual translation infrastructure for all video, live and recorded -- the first and only that works in real time. World translation: not just changing voice and lips into a new language, but understanding the scene, the sound, and preserving the human.

🦋 Movies & TV, Micro-dramas, Live Broadcasts, Live Shopping, Corporate & Education, Ads, Creators & Podcasts, Platforms. Day-and-date, in every territory.

Founders An Zhu Liu, Jibin Song, Mingi Kwon, and Xu Zheng lead a team of PhDs, professors, and researchers from the world's top universities who started the field of joint audio-visual human models and co-authored the current state of the art in real-time human animation. Since 2021: over 10,000 citations and 100+ papers at ICLR, NeurIPS, CVPR, ECCV, and more.

Translation has to be a world model. A translator has to know who's speaking: where every sound in the dense polyphony originates (laughter, layered crowds). Laughter here, a short yell there, a voice from off-screen, someone on screen mouthing words before being interrupted. Everyone else scaffolds separate models and pre-processing; a world model simulates the scene. It's a spatio-temporal reasoner: predicting continuity across frames forces it to internalize 3D geometry, spatial reasoning, and permanence -- of objects, people, and the environment itself. The scene state survives the edit: when the shot pans or cuts away, someone off-screen still exists, still owns their voice, and is still there when the camera comes back. Multiple people, side views, off angles, dense polyphony, fast motion -- the hard cases hold.

Vs ElevenLabs: they lose the laughter, the music, the ambiance -- 270% more background-sound error -- and ours sounds 27.8% more like you. That means no recasting, no ADR, no M&E stems required -- it works from the final mix.

Vs human translators: 100.3% of their quality -- scalable, real time. Published benchmarks: https://thefamiliarlab.com/benchmark

DeepReach Inc.\ \ Y Combinator LogoS2026\ \ • Active • 6 employees • San Francisco

Physical AI — robots and world models — is bottlenecked on one thing: diverse, real-world data at massive scale showing how humans actually do work in the physical world. It was never written down, and you can't buy it, because no one has ever captured it. Only real local experts, the people who do this work every day, can produce data this authentic and valuable.

DeepReach builds the network that reaches them. We design and manufacture wearable stereo capture devices, then place them with local data partners who run collection as their own business — in warehouses, workshops, farms, kitchens and repair shops. They own the local relationships; we supply the hardware, the software platform, the quality pipeline and the payments. Anyone can run a data business.

That structure is what produces diversity. Instead of thousands of hours inside one environment, we deliver hours spread across thousands of environments — which is what actually makes robot policies generalize.

475 devices in the field and 100+ data partners are live across 7 countries, adding new partners every week. They've collected nearly 150,000 clips in the past three months, with volume roughly doubling month over month. Our data is in production with multiple frontier model and robotics companies, and we're scaling to 10,000+ devices across 50 countries.

herdr\ \ Y Combinator LogoF2026\ \ • Active • 1 employees • Ankara, Turkey

Developers don't run one coding agent anymore. They run fleets of them — for hours, sometimes days — across laptops, servers, and sandboxes. Keeping track of that work is the new bottleneck: which agent is blocked, which one finished, which terminal is it in, and why did everything die when the laptop closed.

Herdr is the open-source home for that work. A background server owns the agents' terminal sessions on each machine, so the work survives disconnects, closed lids, and dropped SSH. Herdr detects each agent and turns the chaos into an attention queue — working, blocked, done, across every project — so you look only when an agent needs you. Every client is just a view: the bundled terminal UI, SSH from another machine, your phone. Close one, open another; the work never stops.

Software can drive it too: a CLI, a socket API, and a plugin marketplace that passed 500 community plugins in its first month. The runtime is Apache-2.0 and stays open. Four months after launch: 25k GitHub stars, 340k downloads.

Riften\ \ Y Combinator LogoS2026\ \ • Active0 • San Francisco

Intelligence will be the most valuable asset a company owns. Today, almost every company rents it.

Companies pay a handful of labs one token at a time. Each dollar buys an answer, not an asset. They spend more, but own nothing more.

Riften reverses that.

Change one environment variable and Riften becomes the gateway for a company's AI traffic. We route each request to the lowest-cost model that can do the job, serving most work on open-weight models we host. Customers save money immediately without rebuilding their products.

The gateway is the entry point. Over time, Riften turns the company's work into private models built on open weights and shaped around the business. What begins as cheaper inference becomes an intelligence stack the company owns, runs on infrastructure it controls, and uses to power its most important applications.

We call this earned intelligence. It is created by the company's own work, controlled by the company, and accumulated over time.

The next generation of companies will not rent their intelligence. They will earn it, own it, and compound it. Riften is how they get there.

Rasyn\ \ Y Combinator LogoS2026\ \ • Active • 3 employees • San Francisco

We builds foundational AI models for chemistry. Almost nothing you buy is a single chemical. Products like datacenter coolant, GPU thermal paste, paint, and glue are formulations, which are mixtures of around ten ingredients each, and demand for them has grown quickly because of AI and EVs.

Designing a new formulation is essentially a search problem, because there are more possible mixtures than anyone could ever test, and none of them can be predicted in advance. As a result, bringing a single formulation to market today takes three to five years of trial and error in a lab.

Our models predict how a mixture will behave far faster than the standard methods used today, which lets us design new formulations in weeks rather than years, at a fraction of the cost. To prove this, we used them to invent three chemicals that never existed before, including a PFAS-free coolant for datacenters, and we have since synthesized and patented all three.

We are already working with some of the largest manufacturers to design formulations for them, and we are building our own lab to generate the data that will train our next models.

IMPACT Drones\ \ Y Combinator LogoS2026\ \ • Active • 2 employees • San Francisco

IMPACT builds autonomous interceptor drones that ship in sealed containers. The box sits at the site it protects, data centers, power grids, airports, bases, with no crew on the pad. When sensors cue a hostile drone, an interceptor pierces its own frangible lid, launches, and rams the target, guided by onboard vision that keeps working when GPS is jammed. Legacy effectors cost $1M+ per shot against $30k threats; ours cost less than the threat and scale with the swarm, the same class of interceptor already downing Shahed drones over Ukraine. Sites subscribe to protection instead of buying missiles, hardware, reloads and monitoring included: Air Defense as a Service. 180M+ USD in signed letters of intent.

CarSignal\ \ Y Combinator LogoS2026\ \ • Active • 2 employees • Los Angeles

CarSignal is the AI-native operating system for independent auto repair shops.

Most shops still run each repair across disconnected management software, scan tools, parts catalogs, service information, texts, spreadsheets, and knowledge kept in technicians’ heads. That fragmentation slows diagnosis, creates duplicate admin, and leaves customers waiting.

CarSignal connects the full repair process in one system. AI agents research vehicle-specific failure patterns and surface the tests that confirm or rule out each cause. The same system carries each job from booking and intake through inspections, estimates, parts, approvals, payment, and follow-up, so technicians spend less time searching and updating systems and more time fixing cars.

COACH\ \ Y Combinator LogoS2026\ \ • Active • 4 employees • San Francisco

Coach is the AI sales coach for in-person sales teams.

Reps record every meeting, and our AI figures out what your best closers do differently, then coaches everyone else to do the same, with precise, personalized feedback after every meeting.

Managers finally see 100% of what happens in the field: Coach flags who's stuck and why, so they only step in when it matters, and can coach 5× more reps.

And every meeting feeds one sales brain, so leadership finally gets answers to the questions that used to be guesswork. They finally see the game of their team not just the scoreboard.

Our bet: in the AI era, in-person sales will only matter more. It may end up being one of the last truly human jobs.

Our conviction: any motivated rep can become a great one, meeting after meeting.

The results so far: +32% average lift in conversion rate.

Proprio Robotics is building state-of-the-art physical intelligence to automate the entire data center lifecycle—from buildout to maintenance to decommissioning. There are currently 400,000 unstaffed data center technicians positions in the United States alone, which means the massive compute needs of AI are being bottlenecked by labor constraints. Proprio is solving this by building robots that do it instead, and is deploying data center maintenance robots starting Q1 2027.

Vendo\ \ Y Combinator LogoS2026\ \ • Active • 2 employees • San Francisco

Vendo is the customization layer that lets your users build their own features and micro-apps directly on top of your product. Rather than waiting on an ever-growing feature backlog, your users can personalize the product to exactly how they work, create their own automations, and integrate hundreds of external tools, all without your team writing a line of code.

Everything runs on your existing API, renders natively in your own theme and components, and executes inside secure sandboxes within your existing security guardrails, so your source code is never touched. Companies can plug Vendo into an agent they already have, or deploy a production-ready agent complete with the ability to take actions in the product, generate UI, and draw on a built-in knowledge base. Vendo is open source and installs with a single command, and we work closely with teams to get it running for their product.

Fabraix\ \ Y Combinator LogoS2026\ \ • Active • 2 employees • San Francisco

Fabraix builds state-of-the-art AI red-teaming agents that continuously detect security vulnerabilities in customer-facing AI. Our product, Nyx, has already found vulnerabilities in agents at dozens of Fortune 500 companies. On AgentHarm, the leading benchmark for offensive AI security, Nyx achieved a 78% attack success rate, compared with 67% for GPT-5.6 Sol.

AI agents can change more often than teams can test them. A new model, prompt, tool, permission, or data source can change what an agent does, even when the application code stays the same. And AI is also increasing how much software companies produce and how often it changes. We built Nyx to automate the work required to red-team AI agents. It is multi modal by design and interacts with the target indirectly through controlled replicas of SaaS products and websites that we maintain, placing malicious payloads in webpages, documents, files, messages, and tool outputs to test how an agent behaves under different conditions.

Nyx often finds its first vulnerability within minutes or hours rather than days or weeks. Because the work is fully automated, companies can repeat the test with every change and at a much lower cost than what a 7-figure red-teaming (and point-in-time) engagement would require.

We're also the team behind ACE (Adversarial Cost to Exploit), a benchmark that measures AI security in terms of how much it costs attackers to break an AI system; providing a game-theoretic framework to understand how motivated a rational attacker would be in exploiting the system.

Understudy is an inference cloud. We capture your AI work traces, train smaller models, and automatically deploy them (only when they outperform the expensive model you are currently paying for).

Instead of renting the same frontier model forever, your AI infrastructure gets faster, smarter, and cheaper every time it runs.

Suppose your product uses Claude for a repetitive legal workflow.

Understudy observes successful production runs, learns the specific tools and judgment required for that workflow, and trains a specialized open-weight model.

Once that model matches or beats Claude on a held-out evaluation, Understudy starts routing production traffic to it.

As more work is completed, the model keeps improving.

We started Understudy because we believe every company using AI should be accumulating intelligence, not accumulating API bills.

Zero redeploys. Under 1% CPU overhead. Automatic PII redaction.

We turn 4-hour production war rooms into 10-minute automated resolutions. As agents write and operate more of the world's software, HyperProbe is the runtime observability layer that lets them understand what they built.

Robocurve\ \ Y Combinator LogoS2026\ \ • Active • 3 employees • San Francisco

Robocurve builds open-source tools and independent benchmarks to measure how well robots can do real-world jobs. Instead of relying on unverified demo videos from frontier labs, we score their models on reproducible benchmarks that anyone can trust.

Today there are no well-run, standardized robotics benchmarks. Labs evaluate in-house, and no independent group has stepped in to run continuous benchmarking as a service. The result is that no one actually knows how good anyone else is, or where the real frontier sits.

Good benchmarks require operating and maintaining physical hardware and real-world setups. Simulation only goes so far, since models that look strong in sim can show large performance gaps once deployed in the real world. Building real-world benchmarks means coordinating job-domain experts, evals engineering, and hands-on robotics all at once.

Frontier labs are targeting general-purpose robotics by 2028, yet the field of robotics evals barely exists. Whoever builds the trusted measure of robot capability becomes the reference everyone relies on. We combine backgrounds in AI evals and robotics to build and grow this field as fast as possible. We already shipped v1 of our open-source framework, Inspect Robots, and ran our first pilot scoring a frontier model on a real robot.

Definite\ \ Y Combinator LogoS2026\ \ • Active • 3 employees • San Francisco

Definite is where finance teams build everyday back-office agents on one live model of their books. We plug into your ERP, ledger, payroll, and payments read-only and compile everything into one clean model that stays current as money moves. Your back-office team then builds agents on top in plain English. We never write back and we never move money. The agents are yours, the plumbing is ours.

We met in first year computer science at Waterloo and interned at Meta, Optiver, and BitGo. At Optiver they ran an n8n hackathon and the interns automated basically nothing. It couldn't talk to the systems that mattered. When we pitched banks and fintechs on agents, they kept telling us the same thing. The agent isn't the hard part, getting clean data out of their systems is.

Right now, automating anything in a back office means engineers hand-stitching data from a dozen sources in different formats on different schedules. Tools like n8n and Workato assume your data is already clean and joined. In finance it never is. So the teams with the most repetitive work and smallest budgets get nothing.

The hard part is the compiler. Every source gets cleaned, matched, and joined into one live model of transactions, invoices, vendors, and payments, and it has to stay right as money lands every day.

Everyone throws engineers at this. We're doing it once so nobody has to again. Every back office is getting agents eventually. Whoever owns the data they read from owns the thing all of them depend on, and eventually the books themselves. That's what we're building.

Superlog\ \ Y Combinator LogoP2026\ \ • Active • 2 employees • San Francisco

Sentry and Datadog dump a stream of alerts. Most are duplicates, most lack context, and you still have to solve the issue yourself.

Superlog is AI-native observability that's meant not to be opened. A wizard scans your repo and installs proper OpenTelemetry instrumentation, then runs daily to keep up as you ship new code. When something breaks, Superlog groups the errors into a single incident, investigates with full context (logs, traces, recent deploys, past Slack threads), and posts one mergeable PR in Slack. You merge it, ignore it, or open it as a Claude Code session and modify it.

Telemetry is vendor-neutral, so you keep every log, trace, and metric we install, even if you leave.

Ndea is building frontier AI systems that blend intuitive pattern recognition and formal reasoning into a unified architecture.

# AI for Scientific Advancement

Unlike all life before us, humanity's ascent is a story of ingenuity, not just biological evolution. Our progress has been driven by the curiosity to acquire knowledge, the ability to pass it on, and an intrinsic drive to innovate. We build technology which gives us leverage beyond our biology.

We stand at the top of a knowledge and technology colossus that we collectively created over the past ten thousand generations. Scientific progress has helped us overcome burdens that long defined human life — famines, plagues, and widespread illiteracy. Science will continue to redefine the boundaries of the human condition.

Today, the acceleration of scientific progress hinges on one factor: AI capable of independent invention and discovery. This capacity is the gateway to advancements beyond our wildest imagination.

# A New Research Lab

We're starting Ndea — an AI research and science lab. The name - like 'idea' with an 'n' - is inspired by the Greek concepts ennoia (intuitive understanding) and dianoia (logical reasoning), capturing our first goal to merge deep learning with program synthesis.

Ndea is entirely focused on developing and operationalizing AGI to realize unprecedented scientific progress in our lifetime for the benefit of all current and future generations.

Building AGI alone is a monumental undertaking, but our mission is even bigger. We're creating a factory for rapid scientific advancement — a factory capable of inventing and commercializing N ideas.

From our vantage point today, we see many 'known' frontiers like self-driving vehicles, drug discovery, sustainable energy, robotics, and space exploration. While AGI will benefit all of these, the most exciting adventure lies in the 'unknown'. AGI promises discoveries and progress we cannot imagine today.

Carrot Labs\ \ Y Combinator LogoW2026\ \ • Active • 2 employees • San Francisco

The problem: AI has quietly become one of the largest and fastest-growing line items for companies. Spend is scattered across a dozen provider consoles that each show one number at the end of the month and nothing about why it moved. There's no unified view, and no way to trace a dollar back to the customer, feature, team, or even the pull request that caused it.

Which customers are unprofitable once you subtract their AI costs? Which feature is quietly burning your Anthropic budget? Is this week's spike a runaway loop or real growth? How much did that AI-written PR actually cost to ship? Today teams reverse-engineer answers by exporting CSVs from each provider and stitching them together in a spreadsheet, and by the time they do, the money is already spent.

What SuperPenguin does: SuperPenguin tracks AI spend across 14 providers (OpenAI, Anthropic, Google Gemini, Deepgram, ElevenLabs, AWS Bedrock, Azure, Modal, Cursor, OpenRouter, and more).

\* Zero-code setup: connect an API key and costs sync automatically with model-level breakdowns, trends, and forecasts \* Per-request attribution: add two lines with our Python or TypeScript SDK to tag every AI call by customer, feature, team, or environment (or any other metadata). \* AI coding cost per PR: connect Cursor to see engineering spend attributed to each pull request, repo, and developer, so you know what it actually costs to ship. \* Alerts on budget thresholds and spend anomalies, delivered to Slack, email, or Discord.

Most teams are set up in under five minutes. We help companies see where their AI money goes and whether it's worth it.

Foreman\ \ Y Combinator LogoW2026\ \ • Active • 2 employees • San Francisco

Foreman is the all-in-one AI-powered project management platform built for construction contractors and the trade industry. Today, contractors run complex businesses on a patchwork of tools that were never designed for construction — estimates in spreadsheets, plans in email, proposals copy-pasted from old Word docs, photos scattered across phones. Nothing talks to anything else, and the admin work never stops. Foreman replaces that patchwork with a single platform that manages the full lifecycle of a construction job, from first estimate to final invoice. Contractors upload plans, photos, or a project description, and Foreman's AI instantly generates structured takeoffs, scoped estimates, and professional proposals — in minutes, not hours. From there, every customer record, document, permit, photo, change order, and conversation lives in one place, organized around the job. The result: contractors spend less time buried in admin and more time building. They bid faster, manage jobs with less chaos, and close projects cleanly — without duct-taping five tools together to do it.

Datoric develops custom datasets for voice models, robotics, and world models, treating research, collection, verification, and production as one continuous process. We work closely with frontier model teams to turn emerging limitations into testable data hypotheses, while running our own experiments ahead of customer demand. This allows us to operationalize validated methods into repeatable collection systems at scale.

Data is collected through private invite-only applications separated by modality, customer, and trust level. Every submission remains linked to the contributor, device, task, session, consent, rights, and processing history that produced it, giving our internal QA and fraud models the context to detect problems that may appear legitimate in the finished file. Each collection reveals new failure cases and quality signals that improve the systems behind the next dataset.

Once a collection method is validated, it becomes a reusable data recipe for future custom projects or independently collected, rights-cleared data products. This allows Datoric to turn what is emerging at the frontier into datasets available ahead of broader market demand.

Autonomous Technologies Group\ \ Y Combinator LogoF2025\ \ • Active • 8 employees • New York City

Autonomous is a superintelligent financial advisor at 0% advisory fees.

Today, managing your money means one of two bad options:

DIY your money: You end up with accounts everywhere (401k, IRAs, brokerage, crypto, savings, equity, secondaries). Your spreadsheet is always wrong. You make expensive mistakes because this isn't your full-time job.

Hire a financial advisor: They'll manage your money and charge 1-2% of assets annually. Run that math over multiple decades and you're handing over half your net worth to fees.

Neither path can economically deliver the sophisticated, personalized strategies the ultra-wealthy use to compound wealth: strategic tax-loss harvesting across individual securities, systematic risk management, portfolio-backed borrowing to defer capital gains, access to alternatives, etc.

These aren't secret – they're just economically impossible to deliver at scale through traditional human advisors.

Robos were supposed to fix this, but they were designed in a pre-AI world. In practice they just manage cookie-cutter portfolios. They don’t coordinate across your 401(k), taxable accounts, mortgage, equity, and cash flow, they don’t help with real decisions like job offers, windfalls, or concentrated stock, and they don’t deliver institutional strategies. That’s why, even after a decade plus, the biggest robos are still <$100B AUM while old-school advisors like Raymond James / Edward Jones sit on trillions.

We’re doing for financial advising what Robinhood did for brokerages. Think of it as a full-stack, AI-native wealth strategist that brings billionaire-style playbooks to ordinary investors.

Autonomous is built around a frontier-scale reasoning engine—an AI that perceives global events as they unfold, understanding their deeper implications for markets and and most importantly, how these events will impact your investments.

When Private Equity funds evaluate deals, they pay firms like McKinsey, BCG, and Bain $500K-$1M for market due diligence. The process takes weeks, and the output is a static PowerPoint that's impossible to audit. A single large-cap PE fund can spend >$30M annually on this and the total market is $10B per year.

Our AI agents conduct expert interviews and synthesize insights with every claim linked to source transcripts. No black box, no "trust me" slides, and no 10x mark-up for human labor.

Frederik bought these reports as a Principal at Blackstone. Soren sold them as a Principal at BCG. Harshil is a repeat founder and former Software Engineer at Google. We've seen both sides and know what matters in due diligence - and now we automate it.

Compyle is a less autonomous coding agent that asks before it acts. We're like Cursor or Claude Code - but you won't need to rewrite your codebase every time you use it for more than a small task.

We built Compyle because we were frustrated with the direction other coding agents are headed. They're all racing to be more autonomous, running for hours without human input.

This doesn't work for real production code. When agents run autonomously, they make countless small decisions that pile up in your codebase. Engineers lose ownership - they don't know what was implemented, can't effectively debug or maintain it, and struggle to build on top of it. The code becomes a black box, and they're forced to throw it away.

Compyle keeps engineers in the driver's seat.

We power frontier labs developing robotics foundation models and general-purpose robots by providing the data they need: 1️⃣ Egocentric Data — real-workplace human video with hand/body pose, depth, and subtask labels. 2️⃣ Robot Data — trajectories collected from manipulators and humanoids in real industry settings. 3️⃣ Human-in-the-Loop Rollouts & Evals — real-world deployments with remote operators who recover robots when they fail, capturing data that feeds back into training and continuously improves models.

Additionally, through the Cortex Marketplace, workplaces get paid to host data-collection and evaluation sessions, while labs access the in-the-wild data that truly matters. This draws on Lucas’s previous experience as co-founder of Carousell, a C2C marketplace that scaled to a $1B+ valuation.

Flick\ \ Y Combinator LogoF2025\ \ • Active • 2 employees • San Francisco

Flick is an AI filmmaking software that lets people create Hollywood-level short films completely using AI end-to-end.

There are many AI tools that can give you 8-second casual clips to post on social media, but when it comes to creating truly high-quality films with coherent storylines, consistent characters, and cinematic aesthetics, they don’t come close due to their lack of flexibility, creative control, and fragmented creative flow.

Founded by an award-winning filmmaker and a founding engineer at Instagram, Flick defines an interface specifically designed for native AI filmmaking that feels natural and enables end-to-end creative flows. Think of Flick as Figma for AI filmmaking.

There are 4 complete AI short films created using Flick that got 20+ awards in international film festivals already and our early creator residency community are generating several AI short films every week.

We are also building a community where we produce our own AI films as well as collaborating with other well-known filmmakers to share their “behind-the-scenes” workflows as resuable templates to inspire users in our community. We not only build product, we also build world-class content.

The whole film industry will be revolutionized by AI and our goal is to be “the product” that defines this category.

Sourcebot\ \ Y Combinator LogoF2025\ \ • Active • 3 employees • San Francisco

Sourcebot is an open source code understanding platform for massive codebases. We’re used by thousands of engineers in some of the largest companies in the world, including NVIDIA, Red Hat, Wikimedia, and Arista Networks.

Understanding code, not writing it, is the primary bottleneck for large engineering teams. For developers, this means onboarding onto complex codebases faster. For AI agents, it means getting the necessary code context to minimize hallucinations and maximize cohesion within the wider codebase.

Sourcebot solves this by giving developers and AI agents the ability to regex search across millions of lines of code instantly, as well as ask questions across thousands of repos using any flagship reasoning model. Being open source and on-prem, we can get deployed in enterprises within minutes before other tools even get approval.

We met a decade ago at McGill University and have been building together full time for over 2 years. We’ve personally felt the pain of understanding large codebases while working at Microsoft, EA, Ubisoft, Google, and Meta.

Prox\ \ Y Combinator LogoF2025\ \ • Active • 7 employees • San Francisco

Every product ever sold needs support at some point. That support falls into one of two buckets.

Bucket 1: Simple stuff. T-shirts, screen protectors, keyboards. You buy it, it shows up, maybe you ask “where's my order?” once. This is solved. Zendesk and a hundred other horizontal companies solved it.

Bucket 2: Hard stuff. $20,000 industrial heaters. HVAC systems. CNC machines. Car parts. Products where buying wrong means your building doesn't have heat or your manufacturing line is down. Support for these products can only be performed by highly trained domain specialists and there aren't enough of them.

If you're selling EV charging stations, your support person needs to be a certified electrician who understands local power grids, installation codes, and compatibility matrices. You can't hire this off the street. You can't outsource it overseas.

You'd think LLMs would have solved this by now. They haven't. Three years into the LLM era, penetration in this industry is very low & the reason is twofold.

First, off-the-shelf models don't actually understand these products. The knowledge lives in 48-page technical manuals buried on some manufacturer's website in terrible formatting — wiring schematics, compatibility matrices, installation diagrams that can only make sense visually. A general-purpose LLM can't draw you the diagram showing how to connect terminal A to terminal B. It doesn't have the spatial understanding or the product-specific reasoning to be a real technical advisor. So companies still rely entirely on human experts.

Second, even if the models were good enough, there are no harnesses to make them useful in the business.

No engine to capture deep technical knowledge about complex physical products and keep it updated. No way for a company to offload tribal knowledge from their senior technicians into a system. No way to see what questions customers are actually asking and feed that back into the knowledge base. No generative multimodal presentation and no expressive voice support.

Prox is building the best technical product expert for extremely complicated physical products.

A multimodal agent that can draw wiring schemes, share CAD models, process incoming videos from a technician in the field, and support people over the phone with voice that can pass the Turing test. To get there, we're solving multimodal knowledge graph building at a very deep level. A huge portion of your work will be developing SOTA knowledge engines that can truly understand complex physical products.

Today’s dispatchers face an overwhelming task: balancing regulations, customer demands, live fleet data, and individual driver needs, all while coordinating across siloed tools and teams. Mistakes run rampant, and each mistake is thousands of dollars. Even the select fleets using algorithms that have fleet-wide context struggle: the outputs are rigid, hard to interpret, and are blind to real-world nuances like driver preferences and schedule exceptions. Fleetline solves this by combining advanced optimization with LLMs that can easily adapt algorithms to each fleet’s needs and capture driver-specific information. The result is smarter planning truly optimized for every fleet and its drivers.

Floot is the layer where vibecoded software runs.

SaaS is dead. Hundreds of millions of people already spend their day in Claude or ChatGPT - and increasingly, when they need an app, they won't buy one. They'll describe it, and it will exist.

We're building the infrastructure that makes that real. When Claude creates an app, it needs somewhere for that app to live: a backend, a database, hosting, a domain, the ability to scale, various services, maybe even to be able to work as a mobile app. Floot is that place - a full stack purpose-built for AI to operate, from a specialized framework that defines how AI writes and runs code, down to scalable hosting on AWS.

This means you can now build and ship real apps directly inside Claude and ChatGPT. Connect Floot, and the model you already pay for writes and debugs the code, shows a live preview, and publishes to your own domain. No need to wire up git, vercel, supabase and a dozen other providers. And no AI credits - every message runs on the subscription you already have, because we charge for the platform, not for a token markup.

We built Floot this way because we've watched the model layer commoditize - every serious builder writes good code now, including us. The lasting value isn't another agent between you and the model. It's the layer underneath, from wherever people already are. We're building Floot to be the home for all operation software, for the decades where most new software on earth is written by AI.

Certus AI\ \ Y Combinator LogoS2025\ \ • Active • 8 employees • San Francisco

Certus AI is replacing the restaurant phone line with Voice AI.

Restaurants lose up to $100,000 per year per location from missed calls, lost orders, and abandoned hold lines. Staff are overwhelmed. IVRs frustrate customers. Call centers are expensive and impersonal.

It’s 2025. Guests don’t leave voicemails or wait on hold. They just move on.

Certus is an AI voice agent built for restaurants. It answers every call, 24/7 — taking orders, processing deliveries, booking reservations, upselling, and handling complaints in English, Spanish, French and more. Certus is built to manage the phone line end to end, from the customer call to the restaurant tech stack, with zero human intervention required. It currently integrates with industry-leading systems like Toast, Square, Clover, UberEats, DoorDash, and more.

We’re building the voice layer of the modern restaurant — the employee they’ll never fire.

We started Certus because we lived the pain. Gurveer (CEO) grew up answering phones in his family’s restaurant and helped operate them, growing from 1 to 11 locations in 7 years. Later, he and Adam (CRO) ran a restaurant growth startup to help others increase revenue, but kept watching clients bleed cash because no one picked up the phone. So we built the solution the industry always wished existed.

Until now, this problem was considered unsolvable. But Voice AI has finally crossed the conversational chasm and 72% of consumers now prefer AI over humans as long as it means faster and better service.

More importantly, the market is begging for this. The North American restaurant industry crossed $1 trillion in 2024, and it's projected to hit $1.5 trillion in 2025. Yet over $100 billion is still lost annually to missed calls, human error, and outdated tech. As the market continues to grow, so do the losses!

Our customers say it best:

- “Certus changed my life overnight.” - “We were losing the ability to give great in-house service — the phone was killing us.” - “70% of my business comes through the phone. That’s mine and my 16 staffs livelihood.” - “Before Certus, I used to lose 40 - 60 calls a day…. now my printer just stays printing!” - “I’ve been in the business 38 years. I’ve been waiting for this since then.”

Certus is here to fix the $120B phone problem — one call at a time.

And in doing so, we’re redefining how the restaurant industry communicates forever, starting with the phone line.

You built the demo in a weekend. Now you need auth, a prod-grade database, real-time events, AI observability, cron jobs, email, monitoring… and you needed them yesterday.

We spent a decade at our previous startup, building a $500M platform while scaling to millions of users and customers like Meta & Netflix. Now we're standardizing how web applications are built with an open-source framework and AI App Builder, so non developers can build reliable production apps and not just prototypes.

Modelence is a batteries-included platform with a dedicated web app framework that's designed for building production grade apps with AI, abstracting away the standard building blocks: - Authentication - Database - Hosting - AI integration - Cron jobs - Live / real-time data - Email integration - Monitoring

Most AI app builders just stitch together multiple services and existing frameworks. The reliability drops hard because integrations between different parts break. Modelence defines a single full-stack framework with dedicated cloud infrastructure, where these integrations are already built into the framework and don't need to be built for every app.

Channel3 gives every developer access, opening a world of possibility for new shopping experiences across any vertical. For instance, developers could build AI fashion stylists or give their agents shopping capabilities.

We don’t just collect product data; we actually understand it. With the latest image classification and reasoning models, we can match products across merchants—even when listings and images differ—recognize variants, and surface the perfect matches for every search. As we grow, we’ll capture unique insights into what users want, click, and buy.

As AI models get smarter and cheaper, our flywheel accelerates: our catalog will improve, and it will be even easier for developers and vibe-coders to build on our infrastructure. To further incentivize building on Channel3, we provide built-in monetization; developers earn commissions on sales they drive.

Alex discovered this need while building an AI tutor that could recommend products and earn affiliate revenue. When no solution existed, he persuaded his smartest friend from Duke and former co-founder George to leave Palantir and build Channel3 together.

We launched mid July, and our agent is already operating in production environments, creating appointments in electronic health record apps and processing files in legacy ERPs.

We’ve built the first computer use agent that memorizes tasks and repeats them quickly while still adapting to unexpected changes on the screen. A good analogy is to how humans use computers: once we get used to an app, we use it much faster, while still adapting to random popups and crashes. This new paradigm for computer use will be needed by every company automating human workflows on computers.

We (Brian and Bernard) have been close friends since university, and most recently worked together at Asana, leading AI and Authorization efforts. There we realized AI can completely disrupt the $50B Work Management Market, but it required a fresh start.

What work we even choose to manage in the first place is critical, and the most important insights from customers are silo-ed in sales/CS while R&D gives their best shot at roadmaps meant to deliver impact. Significant requests sit in a backlog, duplicate asks flood the system, months wasted on "strategic investments". We want to bridge this gap.

This message is resonating with heads of sales, heads of product, CEOs, as well as individuals, all trying to make sure the most important things get done, with less wasted effort and more revenue/retention.

Kestral works by automatically take in customer data like sales call transcripts & feature request messages and a team of agents: 1. analyze them for actionable takeaways, deal blockers, and nice to haves 2. consolidate them and manage all the asks with citations 3. prioritize them by impact and frequency to cut through the noise so you can see the biggest opportunities clearly 4. connect them to your existing strategic roadmap so when the work gets done, we can automatically follow back up with your customers and win them over

Cactus\ \ Y Combinator LogoP2025\ \ • Active • 2 employees • San Francisco

HVAC, plumbing, roofing, and electrical companies spend $3K–$25K every month making the phone ring - then lose 10–20% of those leads to slow response times, missed calls, and zero follow-up. The revenue was already there. It just walked out the back door.

Cactus closes that gap on both sides.

Inbound: Every call answered in under 60 seconds, 24/7 qualified and booked directly into Housecall Pro, Jobber, FieldEdge, or ServiceTitan. No voicemails. No missed jobs.

Outbound: Warm leads, dormant customers, and unworked estimates get proactively contacted - driving repeat jobs, cross-sells, upsells, and referrals without adding headcount.

The result: 20–30% more jobs from the ad budget you're already spending.

What that looks like in practice:

→ Roofing company, NC | $299K collected in 10 weeks. $1.41M pipeline created. 199× ROI. $48K of that revenue came in after hours — while the office was closed.

→ Plumbing & HVAC company, UT | $180K confirmed revenue in 4 months. 90× ROI. 58% of captured leads came after hours — jobs that would have gone to voicemail now go straight into the CRM.

→ General contracting company | Grew from 11 jobs/month to 72 in a single month — 555% growth. $2.09M invoiced. $1.82M collected. Zero new hires.

→ Roofing & siding company | $228K pipeline in 75 days. 92% of calls converted to hot leads. $804K in net sales during the Cactus period. 49 spam calls filtered automatically — hours of staff time saved.

→ Commercial signage company | $398K pipeline generated in 10 weeks. 111× ROI on $3,597 invested. Grew from 0% to 30% share of total company pipeline in a single month.

If we don't add revenue, we don't stay. That's the only way this works.

The $150B home services industry is still running on voicemail and spreadsheets. We're building the system that changes that - one answered call at a time.

throxy builds custom vertical AI agents and pairs them with human SDRs and ultra personalised email sequences to book meetings for B2B software companies selling into traditional industries (e.g. manufacturing, logistics, construction, supply chain)

Outbound is broken. Generic automation gets ignored and decision-makers in legacy sectors are hard to reach. Most of your TAM isn't even on LinkedIn, and tools like Clay, Apollo, and ZoomInfo only cover about 65% of the market. throxy fixes this by running bespoke, fully managed outbound systems for software sales teams trying to crack these industries. We use proprietary scraping tools to map your entire addressable market, then combine AI agents with human experts to deliver hyper-personalised email campaigns and human cold calling that is consistently generating six-figure qualified pipelines.

Since 2023, throxy has powered outbound for B2B software companies, from industrial SaaS to fintech providers, replacing the need for internal SDR teams or stacks of tools with a solution that outperforms on both speed and quality. Today, we have a team of 55 across London and Cape Town, booking on average 8 to 12 qualified meetings per month per client, with some clients seeing 20+ in their first weeks after we doubled down on human-led cold calling.

AI handles the data: building custom databases, scoring leads against your ICP, and personalising outreach at scale. Humans handle the conversations: real cold calls, real emails, real relationships. That's the difference between us and every AI SDR on the market.

Our founding team has built AI at JP Morgan, scaled businesses from age 14, and led enterprise sales from Seed to Series D. We're not just automating outbound, we're redefining what sales execution looks like for software companies selling into traditional industries.

We’ve built a full-stack platform on top of the latest NVIDIA GPUs offering confidential computing capabilities, meaning that you don’t have to trade off performance for privacy. We integrate a suite of recent advances in secure hardware technologies, in particular NVIDIA’s confidential compute mode available on Hopper and Blackwell. When combined with Tinfoil’s software stack, companies can prove their security claims like "we can't see and don’t log your queries.” Tinfoil guarantees that all data always stays private and cannot be accessed by anyone other than the end user -- not even by Tinfoil or the cloud provider it’s processed on. Everything can be made end-to-end encrypted and private with Tinfoil.

The founding team combines deep academic and industry experience in security and Internet protocols. Tanya was previously a systems engineer at Cloudflare, where she built Internet security protocols used by billions, and contributed to the Workers AI platform. Jules and Sacha hold PhDs from MIT, where they worked on secure hardware, cryptography, and privacy technologies. Jules has also worked at NVIDIA on their confidential computing team. Tinfoil was born from our personal frustration with the false choice between access to powerful AI and the massive data privacy implications of deeply integrated AI.

AI is a universal tool that becomes part of our personal lives and business workflows. In the process, it needs access to all personal, private, and proprietary data. Right now, the only solutions are data processing agreements (i.e., "pinky promises"), band-aids like PII redaction that don't work in practice, or AI locally/on-prem, which doesn't scale. Tinfoil promises to unlock significantly deeper AI adoption and integrations by making it easy to obtain true privacy, just as TLS on the Internet enabled e-commerce to flourish by securing credit cards on the network.

Today we offer several self-serve products:

- A consumer-facing chatbot that keeps your chats end-to-end encrypted and provides zero-access inference with powerful open-source models like Kimi, Gemma, and GLM. You can try it out for free: https://chat.tinfoil.sh

- A developer-friendly API that allows you to build AI applications where all user data is kept private and we as the inference provider cannot see any of the prompts. Our SDKs make sure that all relevant security measures are checked for you before even sending a single byte of data. Learn more:https://docs.tinfoil.sh

- An advanced confidential computing platform we call Tinfoil Containers that allows you to secure any Docker application. We make it easy to deploy your own logic and applications inside secure enclaves and prove to the world what code is running inside. This enables attested workloads and publicly verifiable privacy policies for sensitive applications. Learn more: https://tinfoil.sh/containers

Text.ai\ \ Y Combinator LogoP2025\ \ • Active • 4 employees • San Francisco

We're building the first group chat with social skills.

While everyone else is stuck with boring individual chatbots, we've cracked the impossible: Alfi reads the room, understands each person, and creates custom intelligence for every group chat.

Alfi is your new social friend. The one who remembers everything, plans effortlessly, and keeps the crew together.

Here's what that looks like:

- Book restaurants together, with Yelp built in, directly in the chat. No more "where should we go?" spirals. Reserve instantly. - Create images with your friends: drop your crew into funny hats, wild scenes, anything you can dream up. Multiplayer image gen, first of its kind. - Social calendar: upcoming hangs, all in one place. Everyone on the same page. - Group Wrapped: who's the chattiest? Top inside jokes? Now you'll know. - Reminders & Memory: Alfi remembers your spots, your preferences, and nudges you to actually hang out.

We're in the middle of a quiet shift. Gen Z is leaving broadcast social media. They're retreating to group chats, smaller, more intentional and personal spaces where they're honestly themselves.

But group chats are also where plans go to die. Someone has to be "the planner" or nothing happens.

We believe the group chat is the real social network. Where the funniest moments and real conversations happen in real time. With Alfi, we hope to bring you together more expressively, a lot more often.

This technology will bring humanity closer than it's ever been before. Not replace connection, deepen it. That's the future we're building toward.

Our engineers start by reviewing your current setup and agreeing on what quality means for your workflow. Then we train a model on your data. Once it ships, new cases feed back into training so the model keeps improving.

The result is a model that runs faster, improves with use, and is yours to own.

Cardamon\ \ Y Combinator LogoW2025\ \ • Active • 2 employees • London

Cardamon is an AI powered platform that ingests relevant regulation, understands what applies to each regulated financial firm, and gets compliance officers from regulation, to obligations, to product requirements in minutes - not weeks.

Financial firms face a host of complex regulations that make it incredibly painful to launch and maintain products in a compliant way. As a Product team at Revolut, we felt this pain deeply ourselves - we had products ready to launch but stuck in compliance limbo, often for weeks. Turns out, getting compliant took as long as building the product itself.

Frustrated, we dug in and were shocked by how manual and inefficient the processes were. That’s when it clicked: there’s a huge opportunity to automate the boring stuff (and solve our own problem!). Compliance teams win because they ditch the tedious tasks. Product teams win because they ship faster. Everyone’s happy.

When we met at Stanford 4 years ago, it was rare for startups to work with the US Government. In the years that we’ve been involved in the burgeoning Defense Tech ecosystem, a lot has changed. Silicon Valley and the US Government are closer than they’ve been in decades.

As fellows in Stanford’s Center for National Security Innovation, we’ve had the privilege of speaking with dozens of government officials who have come to Silicon Valley looking to fund and scale startups solving their most urgent problems.

However, we’ve seen firsthand the struggles these startups face in securing gov funding. Marcus, having spoken with dozens of defense startups in his time helping lead the Stanford Defense Tech Club and trying to set up a national security startup accelerator has seen this especially.

That’s why we’re making it easier to find and apply for opportunities, taking the application process from weeks to days.

We’re only going to see more cooperation in the coming years. With that, there will be increasingly more funding going towards companies in defense, energy, biotech, quantum, etc. Candor lets you unlock that funding potential.
