PG tweeted: "I bet 3 founder generations is not the record. Anyone know of a longer chain?" Challenge accepted. FounderTrace maps the entire YC founder genealogy — 6,000+ companies, showing who worked where before founding what. Discover 4-generation chains, see which startups are "founder factories" (Stripe alone spawned 50+ YC companies), and explore the family trees of tech's most successful companies. Vibe coded with Crustdata APIs. Free. No signup.
