Before becoming founders, Arvind Veluvali, @sir_aymansaleh, and @yanovskyd all worked at NASA, where they learned to tackle hard problems, run experiments, and keep going when the outcome was uncertain.

Supabase (YC S20) is one of the fastest-growing developer platforms in the world, with more than 10 million developers using it. As AI coding agents like Claude Code, Lovable, Bolt, and Codex have taken off, they've become the backend powering millions of AI-generated apps.

At Startup School Paris, @Supabase co-founder and CEO Paul Copplestone (@kiwicopple) sat down with YC's @dessaigne to discuss why AI coding agents have changed the way developers build software, how open source helped Supabase compete with the cloud giants, and why the next frontier is self-driving databases.

Congrats to @meticulousgabe and meticulous.ai on their $15M Series A!

AI agents are writing code faster than developers can review and test it, creating longer review cycles and more bugs. Meticulous fixes that by analyzing a codebase and simulating user flows before and after every code change, so developers can see the full impact in minutes rather than hours.

In the past year they've grown ARR 5x, with customers including Notion, ElevenLabs, Dropbox, and Wiz.

AI-Native Compliance Infrastructure
@DaivikGoel 

Financial compliance still runs on spreadsheets, disconnected software, and growing teams of specialists. As companies expand into new markets, the cost and complexity of staying compliant can grow faster than the business itself.

AI could monitor regulatory changes, flag anomalies, generate reports, and maintain audit trails in real time. The opportunity is not just to automate compliance work, but to rebuild the entire compliance stack around AI.

Self-Maintaining APIs
@GaddipatiHarsha 

APIs change constantly, but the way providers communicate those changes is still broken. Breaking updates go unnoticed, new features get buried in changelogs, and customers often find out only after something stops working.

Coding agents make a better model possible. Instead of announcing a change, an API provider could find every affected use in a customer’s codebase and open the pull request itself.

Proving You’re Human
@maxkolysh 

A finance worker recently wired $25 million after joining a video call with his CFO and colleagues. Every other person on the call was a deepfake.

As voice and video become easier to fake, the internet needs a new trust layer: a private, reliable way to verify that there is a real human behind a call, message, review, or transaction.

Data for the Real World
@sdianahu & @_austintindle 

AI has become superhuman at code, language, and images because it has enormous amounts of data to learn from. But our understanding of the physical world is still limited by sparse sensors and models built largely on intuition.

Cheaper sensors and better foundation models could unlock entirely new datasets for energy, agriculture, logistics, construction, and the climate. Once you can accurately model the physical world, you can begin to control it.

Most of the global workforce does not sit at a desk, but the software used to manage physical work has barely changed in decades.

The next operating systems will coordinate humans, robots, and AI agents together. The companies that build them could manage far more than software workflows. They could manage the labor itself.

As intelligence gets better and dramatically cheaper, nearly every consumer category opens up again: education, health, finance, entertainment, transportation, and how we connect with each other. Consumer is going to be so back.

Multiplayer AI
@aaron_epstein 

The best work tools became more powerful when they became multiplayer. But AI is still mostly trapped in private chats, with agents working in sessions that teammates can’t join or influence.

The next generation of AI tools will let teams work with agents together in real time: watching, redirecting, and handing off work across engineering, sales, support, legal, finance, and more. AI’s multiplayer moment is coming.

AI could give every child a patient, adaptive tutor that grows with them over the years, beginning with reading, writing, and arithmetic, and eventually helping them learn to think and reason. For the first time, Neal Stephenson’s Primer is starting to feel possible.

PostHog (YC W20) started as an open source product analytics tool. Today, its AI systems are already generating a portion of the company's own pull requests, and its vision is much bigger: self-driving software that identifies product problems and automatically ships fixes.

Congrats to @jmorgan, @mchiang0610 and @ollama on their $65M Series B!

They built the easiest way for developers to get up and running with open models, and it's become the leading platform for exactly that, with 8.9 million developers and 85% of the Fortune 500 using it today. All with just 14 employees.

Most founders obsess over dashboards and aggregate metrics, but some of the best product insights come from understanding how individual users actually use their product.

In this episode of Startup School, YC's @dflieb walks through one of his favorite tools for better understanding your users, the dot plot. It's a simple two-dimensional grid that reveals usage patterns no aggregate chart can show you.

He’ll cover why it gives founders a better sense of product health, what patterns to look for, and real-world examples of how dot plots helped teams at Google Photos and PayPal.

Congrats to @joinfleek on their $25M Series B! 

The secondhand clothing market is a $200B+ industry and growing 3x faster than new apparel, but almost all of it still runs on manual assessment and offline trades.

Fleek is building the AI-native marketplace to modernize it, using vision-language models to identify, grade, and price garments in seconds, then matching inventory between 2,000+ suppliers and 50,000+ resellers across 100+ countries.

Gusto (YC W12) recently surpassed $1 billion in annual revenue and now serves more than 500,000 small businesses across the US. Today, one in five new businesses started in the US uses @GustoHQ.

In this fireside, Gusto co-founder and Head of Technology Eddie Kim (@edawerd) sits down with YC's @harjtaggar to talk about Gusto Co-Founder, a new AI product that automates recurring business processes end-to-end, all triggered through SMS or Slack without the business owner ever logging in.

Eddie shares how an experiment with OpenClaw led to the idea, why he believes AI agents need to move beyond the "blank canvas" of chat, and how AI is making it easier than ever to start and grow a business.

Congrats to @surtrdefense on their $4.8M seed! 

Counter-drone operators today juggle a wall of screens: sensors, radars, and effectors that don't talk to each other. Surtr pulls it all into one interface and can automatically cue a response to incoming threats. They already tested in Ukraine, detecting and tracking FPV drones with under 100ms of latency.

Congrats to @useAgave on their $15M Series A! 

They're bringing AI to construction's back office, automating the invoice processing, job costing, and financial reconciliation that accounting teams still do manually across disconnected systems.

With over 500 customers and nearly $100B in construction volume on the platform, they've been profitable for two years and have nearly tripled revenue year over year.
