Founding Engineer @ Cape

About Us

We’re venture-backed founders building AI for professional relationships (eventually all relationships). Our first power use case is an agent swarm that helps startups get warm intros to their dream customers & investors. We’re run by an experienced team (founders have 10+ years at YC-backed startups, ex-Stanford / Harvard), seed funded, and have found early pmf with several dozen companies ranging from Seed to Series C.
