Dan Barrett
Founder of OpenProse, An open-source operating system for reliable long-running agents
Company
Dan Barrett is listed as a founder of OpenProse. OpenProse is building open-source infrastructure for long-running AI work: a declarative language plus the Reactor harness/runtime for reliable agent workflows. Our organic open-source traction (7k+ installs) has already translated into a customer at a medical research lab, starting with a $10k pilot set to roll into a $10k/month contract. YC recruited us into the current batch and we've since hired two senior founding team members (ex-Google, Forbes 30u30 harness engineer). All three founding team members are two time founders. We've raised $1.25M in the last two weeks from Jonathan Abrams 8-Bit Capital, Otis Chandler, and other angels.
