FounderTrace
Explore founder family trees across Y Combinator startups
Visit foundertrace.com ↗What is FounderTrace?
FounderTrace maps the genealogy of Y Combinator companies by tracking founder connections. It catalogs nearly 6,000 YC startups and identifies chains where founders previously worked at other YC-backed companies before launching their own ventures. Users can search for any YC company to see its founder tree and discover which startups have spawned the most subsequent YC founders—Airbnb leads with 83, followed by Stripe with 67.
The tool highlights founder factories and acceleration patterns, showing which companies have been most prolific in seeding new YC startups. The maker says it was built using AI coding tools to generate the genealogy chains and package them into an interactive web application.
