I'm working on Proximal to help bring superhuman coding agents to the world.

Our founding team includes early engineers and researchers from Cursor and Prime Intellect, and second-time exited founders.

If the problem of how to train the best coding agents is interesting to you, we're hiring!

We are backed by top funds and angels from OpenAI, Anthropic, Thinking Machines, xAI, Meta Superintelligence, Cursor and Cognition.

I studied business and CS at USC, before dropping out for Y-Combinator. During YC, I spent some time tinkering with diffusion models and trained a SOTA diffusion model for virtual try on. I also worked on an agent that helped people shop for clothes online.

Previously, I built a logistics software startup that I bootstrapped to $1.5M ARR and sold for $9m.

If I'm not working, I read, write, build things, and meet other interesting people. If that's you, say hi.
