Jack Dreifuss is the Founder and General Partner of Impatient Ventures, where he backs founders with relentless drive and clarity of vision. Before launching Impatient as a solo GP, Jack was a professional online poker player, a hedge fund analyst, a two-time zero-to-one operator with successful exits at SimpleLegal (CRO) and Bolt (CSO), and a 2x venture backed failed founder. 

Along the way, he mastered pattern matching across disciplines—whether reading tells at the poker table, spotting signals in the markets, or scaling companies from inception. 

Outside of Impatient, you can find him obsessively tracking his health metrics (h/t Protocols.co), cruising Venice in his lifted golf cart named Jodi, making music, hosting dinners at the restaurants he’s a partner in (Carmel in West Hollywood, Kitchen in the desert in Joshua Tree), or competing in the World Series of Poker in Vegas.
