About

Gigi Levy-Weiss is a former Israeli Air Force pilot who uses his pilot training to identify high-agency entrepreneurs who stay calm under pressure, and he brings deep hands-on experience as a repeat founder and CEO of major public companies like 888 Holdings before becoming a VC. He's known for his data-obsessed approach to evaluating startups through detailed retention and engagement cohorts rather than vanity metrics, and he champions a philosophy of running thousands of simultaneous experiments to build learning organizations that can exploit AI agents for ultra-lean operations.
