Impatient Ventures

Impatient Ventures is a pre-Series A venture capital firm founded in 2015 and based in Los Angeles, California. Led by solo General Partner Jack Dreifuss — a former professional poker player, hedge fund analyst, and two-time operator with exits at SimpleLegal and Bolt — the firm backs mission-driven founders at the earliest stages, positioning itself as the first and most hands-on member of the cap table. Its investment thesis centers on two macro themes: physical production (embodied innovation in robotics, advanced manufacturing, defense, semiconductors, and biotech) and human connection (AI-driven consumer experiences). The portfolio spans roughly 47–49 companies and includes two unicorns, Flexport and Underdog Fantasy. Fund size and check size are not publicly disclosed.
