Team Structure

E29 Ventures works alongside a distributed network of technologists, engineers, and domain specialists across the E29 ecosystem. Venture-specific teams are formed at the portfolio company level, with each entity operating under its own leadership and governance. E29 Ventures does not operate companies or deliver services—it builds, backs, and spins out independent ventures designed for scale.
