E3Ventures Information

E3 Ventures is the fractional Chief Revenue Officer practice of Sam Lee, built for Series A and B startups that have found product-market fit, raised, and hired — but haven't yet built the revenue engine to hit the number reliably. Sam partners with founders and their go-to-market leaders to find what's holding growth back and then build the unlock. The work follows a simple arc — Evaluate, Engineer, Execute: a clear-eyed diagnostic, the design of the revenue system it calls for, and the hands-on work to put it in the field. He doesn't take your CRO's seat; he sits next to them, as a partner who's already built what you're asking them to build. Sam started his career in finance and strategy at Goldman Sachs and became a public-company P&L owner and general manager in the internet industry by 30. Over the two decades since, he has worked with more than two dozen venture-backed companies to launch, grow, and scale new products — taking revenue from millions to hundreds of millions in ARR, including as SVP and Head of Growth at WeWork and Chief Revenue Officer at LeafLink. Engagements run embedded, as an advisor, or as a scoped project. The goal is never to make you need him — it's to leave you with a revenue function that runs without him.
