Anthropic co-founder Ben Mann on why he chose Montessori for his daughter: "If this were 10-20 years ago, I'd be lining her up for top-tier schools and extracurriculars. But now I don't think any of it's going to matter. Learning facts is going to fade into the background. What…
Ben Mann (@8enmann) left @OpenAI in 2020 with the entire safety team to co-found @AnthropicAI (now reportedly valued at over $100B). In a rare interview, Ben opens up about: 🔸 What he saw at OpenAI that convinced him to leave 🔸 The AI nightmare scenarios that concern him…
That's what @garrytan, President & CEO of @ycombinator, said about him: “His perspectives are exactly what our founders need”. Meet @kul, twice-exited YC founder who just launched a new fund investing exclusively in YC startups. forbes.com/sites/dariashu…
This is pretty awesome. Until now, I wasn’t aware of a great benchmark for visually appealing design and this has been a key area where codegen models fail in my experience. Excited to see @designarena_ai release a new benchmark and try to solve this!
Three weeks ago, we started building an AI game engine. But some models kept making things look... sloppy. So we turned finding the best one into a game. In three weeks, that game grew to 35K+ users across 135 countries. Introducing @designarena_ai, the fastest-growing…
You can now build a Deep Research Agent over your organization's data in literally 1 tool call using @ZeroEntropy_AI's MCP server! We just launched our MCP server, which you can connect to the @OpenAI Deep Research API! This demo shows to find ZeroEntropy's secret buried in…

It took Supabase: * 5 years to get to 1M developers * 4 months to get to 2M * 3 months to get to 3M Absolutely insane acceleration.

The Trim Transformer is designed for training generative AI physics models. On 2D Navier-Stokes it achieves a 90% reduction in memory usage and a 3.5x speedup.
yc helped us pivot **twice** until we found PMF I remember our first interview was basically - "hey from your experience here can you think of other ideas for your startup" haha
YC is one of the few places in the world where your partners will drive you to pivot towards product market fit very consistently

Varun Mohan and the team at Windsurf built something great. What I heard is every founding engineer (over 40 of them) cleared 7 figures. The remaining org of 200 was only 15 engineers who had worked there less than a year, the rest were sales and ops, and even then they left…
X is a retarded place for crypto. Many new entrants fell victim of those big account that calls for $500 ETH at the bottom and $50000 eth now. If you are in crypto for the long term, you should slowly migrate to @farcaster_xyz where you meet real builders and seeing real…
Brought the toddler up to San Francisco thinking we’d probably dressed her too warm but better safe than sorry. Narrator: They had not, in fact, dressed her too warm.

Coinbase has now entered the top 100 of stocks in the S&P 500 by market cap at $110 Billion. Today passing Lockheed Martin, Nike, Starbucks... $COIN
Sieve is growing fast and needs engineers!
The last two months have been insane. I randomly came into the office this morning and decided to record this video on why there has literally never been a more exciting time to join @sievedata. We're working with leading research teams pushing the frontier of creative, robotics,…
9 years to get to $10M ARR; 9 months to $100M+. Replit is a story of a founder with a vision finally unlocked by AI.
Amjad Massad (@amasad) started Replit to make programming accessible to anyone, anywhere. What began as a tool for learning to code has grown into a platform pushing the limits of AI-assisted software creation and recently surpassed $100M in ARR. On The Breakdown with @t_blom…
this photo was taken exactly two years ago at the scale ai hackathon this is where soohoon, vaishant, and i wrote the codebase indexing algorithm that would later become a key part of what makes greptile work it was also that night after the hackathon that we applied to YC…

incredibly grateful to @SenatorCollins for her work on this
