Brian Singerman: "If SpaceX Didn't Work, Founders Fund Wouldn't Exist"

Brian Singerman spent 17 years at Founders Fund, where he helped drive large concentrated investments into companies like SpaceX, Palantir, Airbnb, Stripe, Stemcentrx, Anduril, and Affirm. He recently left to co-found GPx, a new fund backing emerging managers. In this episode we break down the philosophy behind Founders Fund's concentration strategy, how a lifetime of competitive strategy gaming shapes the way he reads founders, and why he is now applying the same framework to GPs instead of companies. "When I did get to meet Elon and learn more about SpaceX, it was extremely clear that there was nobody else like him on the planet who could actually pull something like SpaceX off." The conversation runs from his 2008 start at Founders Fund and what he learned from Peter Thiel, to the SpaceX bet the firm staked its career on, why he has never read a financial report, and his read on genuinely authentic founders like Cyan Banister, Palmer Luckey, and Alex Karp. Plus a round of questions submitted by Max Levchin, Trae Stephens & Scott Nolan, his views on wealth taxes and asset seizure, and his bet on N-of-1 human cultural artifacts.
