A*'s broad investing: biotech to defense

Kevin Hartz, Co-founder of A*, Eventbrite, Xoom, and Sauron.

Kevin has been building and investing in technology companies for 30 years, and we talk about how the industry’s evolved, why he calls AI the Mother of All Bubbles, why we’re still early, and lessons today’s breakout AI companies can learn from those that survived the Dot Com Crash.

Kevin is a big proponent of backing young founders. A significant percentage of his latest fund at A* is invested in teenagers, and he shares how he identifies outlier talent so early, from Seed investments in Airbnb, PayPal, and Pinterest, to many of today’s hottest AI companies.

He also shares the insane story of investing 100% of the proceeds from his first startup into PayPal’s Seed round, how PayPal’s early fraud systems inspired Palantir, what he learned from the PayPal Mafia, from Peter Thiel, and what makes Founders Fund special.

We also talk about how he and his wife recently had two babies, five months apart, using genome screening and surrogates.

Thanks to Ramtin Naimi, Navya Gudimetla, and Bennett Siegel for helping brainstorm topics for the conversation.
