Calvin Chen

I'm working on Proximal, a research lab for data. We help companies evaluate and create data to help them train AI models, starting first with coding capabilities.

Our founding team includes early engineers and researchers from Cursor, Prime Intellect, Jane Street, and second-time exited founders. We're hiring!

We're growing at a rate that puts us in the fastest growing startups ever and are backed by top funds and angels from OpenAI, Anthropic, Thinking Machines, Renaissance Technologies, Google Deepmind, xAI, Meta Superintelligence, Cursor and Cognition.

I sometimes invest, write things, and play golf. I love to chat with new people, feel free to reach out on Twitter!
