Michael Raybman
CTO at Umami Capital
San Francisco, California, United States
Summary
👤
Senior🎓
Top SchoolMichael Raybman is a pragmatic CTO and technical co-founder who helps early-stage companies break through engineering stagnation and scale product teams rapidly. Over eight years he’s led 17 CTO/founding-engineer engagements, helped raise $35M+, hired 100+ engineers and leaders, and steered multiple exits and profitable businesses from MVP to mature P&Ls. He excels in short, intense 6–18 month turnarounds—resolving stalled velocity, outsourcing failures, cofounder splits, runaway budgets, and crushing technical debt while recruiting permanent leadership. Equally comfortable shipping code and building systems as he is advising investors, Michael also angel-invests and co-leads deals where his edge is accelerating engineering velocity. A hands-on builder since early web startups and research software, he brings a rare combination of product instincts, executional rigor, and operational experience scaling teams under pressure.
