Everyone talks about data, compute, and algorithms as the trifecta of AI progress. But evals deserve a seat at the table. In the RL era, with the right evals, you can reduce data needs, generate synthetic data, speed up iteration, and steer models more precisely. The key.

So much talent left on the sidelines at Windsurf and Scale after their "acquisitions". If I were a founder looking to hire, I'd figure out who the top performers at these companies are (not limited to engineers) and get on calls with them ASAP.
If you were part of Windsurf and got left behind, we’d like to talk. Replit is hiring, and we want to hear from every one of you. We’ll move fast and be respectful of your time. We’ve passed on many acquisitions over the years, and any liquidity has always included employees.
