Summary
👤
Senior🎓
Top SchoolJacek G is a founder and operator with 13 years of experience turning dysfunctional product and technology organizations into revenue-generating engines, including three exits and a product studio grown to $2.8M ARR. He specializes in turnaround roles—board-appointed CPO/interim CEO and enterprise delivery restructures that tripled deal size and created financial instrumentation from scratch. Jacek now advises PE firms on product and technology diligence and serves as a fractional CPO, with a knack for finding what’s broken before acquisition and fixing it after close. He’s building production AI products focused on agentic workflows and orchestration that replace FTE roles, bringing theory into deployed systems. Active in Web3 and early-stage investing, he blends hands-on product strategy with startup studio execution and has been recognized by Webby Awards and SVIEF. Based in Miami with an ESADE MBA, he pairs operator grit with a contrarian eye for operational leverage.
