Loved seeing earnest founders sharing what they've learned from the frontier with other likeminded builders at YC Startup School. Thanks @Richard__Zhou and @RayXu_official for the off-the-record talk about autoresearch at @Aemon_ai.

Live in the future. Then build what’s missing. The stage is ready at YC Startup School 2026 🚀 – at San Francisco, CA

That’s a wrap on YC Startup School India. Bengaluru, you really brought it. We can’t wait to see what you’re going to build.

@_groww is now a public company and is the largest investment platform in India. @lkeshre the founder and CEO is still the power user of the product he’s built and still talks to users today.  Had the privilege of sharing the stage at Startup School India where he spoke about building a generational consumer company. We talked about product taste as being not just what looks good, but intentional design choices informed by an obsession with the customer. Lalit and how the team at Groww builds products exemplify this. Photo credit: @gcs319

@harshilmathur built the largest payment platform in India by being obsessed with his users, having relentless conviction in a competitive space and never losing the ability to move quickly, even today at their scale. Thank you for sharing the @Razorpay story with Startup School India.

Insane builder energy. Let’s go Startup School India!

Manufact (YC S25) is throwing their Full Day MCP Apps Hackathon at the @ycombinator office in SF on Saturday, February 21st. Build with the @manufact SDK, meet fellow builders, and win a guaranteed YC interview. I’ll be judging, see you there!

Kicking things off with thousands of the best AI researchers and builders in the world @ycombinator AI Startup School.

All systems go for AI Startup School tomorrow!
