Y Combinator and Partners on LinkedIn

3 years ago, we were 50 people at the Y Combinator event in Stockholm. Wednesday night, 1350 showed up. The job to become the Silicon Valley of Europe is still up for grabs, and Stockholm is in the running. Tack. Ha det fint! 🇸🇪

If you're an AI researcher or an engineer interested in the latest research, come join us at YC Mountain View to talk about the most interesting recent papers. Starting May 20.

Congrats to Rez Havaei and the General Analysis team. One thing most people haven't internalized yet: when capable AI agents interact with each other, a stronger model can pressure a weaker one into overriding its own safeguards - in ways you'd never catch testing either system alone. As agents proliferate, this attack surface explodes. GA doesn't just add guardrails - they run adversarial simulations to find the failures before attackers do. Important new approach.

After the Y Combinator event in Stockholm next Wednesday there will be great afterparties for attendees! SWENODE.AI is opening up TAK's rooftop for a private afterparty — builders, investors, and the people moving Swedish tech forward. You will need a confirmed RSVP to join https://lnkd.in/g_xNaf9E Organized by SWENODE.AI together with: Wilson Sonsini Goodrich & Rosati Dell Technologies Legora Inception Fund Google

Less than a week left to the Y Combinator in Stockholm special event on April 29th with Paul Graham, Jessica Livingston, Max Junestrand and myself. Apply to attend here: https://lnkd.in/g_xNaf9E

It's kind of nuts that the state of the art for e-commerce storefronts hasn't changed in 2 decades. I suspect AI will change this.

New AI benchmark just dropped - table extraction. Extracting complex tables turns out to be both difficult for LLMs and very economically valuable. For the first time there's a benchmark for it.

Did you want to try my GBrain OpenClaw knowledge wiki but didn't want to set up OpenClaw yourself? Now there's a fully hosted option https://lnkd.in/gfDEm7Wb

oh nice, in this piece Vivek Gupta uses claude code to demonstrate a point around gpu/npu resource thrashing that ill admit i hadn't totally understood until reading this. really cool to see the kind of clarity you can get now from a technical person that can get hands on with code while having a ton of relevant experience

There is still time to apply for the Y Combinator special event in Stockholm on April 29th. Join us and hear from: • Paul Graham & Jessica Livingston (Founders of Y Combinator) • Max Junestrand (Legora, W24) • Gustaf Alströmer (YC Partner) Apply to attend: https://lnkd.in/g_xNaf9E

Grateful for the legendary founders speaking at Startup School India today. Aadit Palicha from Zepto Harshil Mathur from Razorpay Vidit Aatrey from Meesho Lalit Keshre from Groww Mukund Jha from Emergent Varun Vummadi from Giga These six founders have created $25B of market value and 250,000 jobs in India.

GStack v1.0 just launched. If you tried it earlier before general release, it was very very chatty. Now it is streamlined and gets you to a completed product much faster. Try it with Claude Code or Codex now. It's free and open source and is exactly my setup for agentic engineering. https://lnkd.in/gDJRzGNr

Getting ready for YC's first-ever Startup School India, in Bengaluru. We've done SF, NYC, London, Paris. This is the first time we've brought Startup School to India.

Congrats to SolidRoad on raising their Series A! ‘‘Twas an honor to work with them during YC and to see them growing up, up, up!

Acts 17 is coming to NYC April 30 for a convo with Kareem Zaki and Saquon Barkley on what truly matters. Don’t miss it http://luma.com/enough

we hosted a multimodal researcher lunch at YC with the Sieve team, who've been doing really good work in multimodal data we got researchers from several frontier labs in a room together and the conversation ranged from robotics to world models to computer use agents. more of these coming soon!

These are the best AI avatars I've seen. Try it yourself here: https://lnkd.in/gpV9Ptt4

Congrats to William, Sky, and Matthew on raising $20M!

I just release v0.10 of my personal GBrain, which is my memory, skillpack and code that makes my OpenClaw my own. As I build my OpenClaw, I release it as GBrain, a system that will help you build your own. This is how personal software now works. https://lnkd.in/g5wzSRYv available now, MIT licensed free open source

Simaril (YC Spring 2026) is SOTA prompt injection defense for LLMs. This is the missing link for OpenClaw for Enterprise and all agents working on mission-critical data and workflows. The cofounders were the team that stopped billions of dollars worth of damages at Amazon.com and AWS. https://lnkd.in/gVKp7qbg
