I asked people: "who have you met in the AI data and post-training space that you find most insightful?" 5 votes: Daniel Chang (@dnnssl2) 3 votes each: - Abhijay Rana (@abhijaymrana) - Ryan Wexler (@RyanMWexler) - Sean Cai (@SeanZCai) - Will Brown (@willcb) 2 votes each: - Amy Tam (@amytam01) - Jesse Hu (@huyouare) - Nikhil Namburi (@nikhilvnamburi) - Thomas Liao (@distributionat) 91 people were picked. The other 82 got 1 vote each and are in the next two posts. People couldn't pick themselves. I didn't vote.

Terac was started with the idea that agents would be running businesses and humans would be needed on-demand to inject context and judgement at key decision points I'm excited to see this come to life in a few weeks in NY and can't wait to share what @whop and @tryterac have been working on together
In 3 weeks, we’re hosting the Zero Human Company Hackathon at the @whop HQ in NYC with @ExaAILabs and others. In August, we teamed up with @stripe, @Lovable, @whop, and others to host the World’s First Zero Human Company Hackathon in SF where we gave out $12,000. In 12 hours, over 200 competitors launched 49 fully autonomous companies. Everything from fractional CFOs, landing page agencies, to data collection for robotics, fully automated by AI. This time it’ll be even better. We’re filling the room with the best founders, engineers, and operators. If you want a spot, we’re still accepting applications: luma.com/naxtga5l

We're excited to announce a $4M Seed round led by @GameChangersVC, with support from incredible investors including @scooterbraun, @GuyOseary, @stellation, @SignalFire, @MaCVentureCap, and others. A few years ago, while hosting community events and testing early products, my co-founders @WeilynChong, @NathanAhn, and I noticed a consistent pattern. After every event, people asked the same questions: Where are the photos? Who captured that moment? How do I reconnect with the people I met? fortune.com/2026/06/16/photo…

Most seed founders think they have a channel problem. It's almost always a messaging problem. Wrote up my playbook based on time at Ramp and OneSchema: substack.com/@willgenesen/p-…

Today, we’re sharing a new state of the art for computer use. Our system holds the two highest verified scores on OSWorld, the standard benchmark for AI agents that operate a computer like a person: 83.6% using Claude Opus 4.7 and 81.5% using Claude Sonnet 4.6. The human baseline is 72.4%. 🧵 1/7
