Founders all the way down

We're founders ourselves, we back founders, and we're backed by world-class founders. Fifty Years is backed by 44 founders of tech companies valued between $1B and $100B who want to help the next generation of founders change the world for the better. We call them the League of Giants because 50Y founders can stand atop their shoulders.
