David Aronoff spent nearly 30 years as a traditional venture capitalist at Greylock and Flybridge before deliberately pivoting to climate investing at My Climate Journey Collective, motivated by his children's questions about what his generation would do to fix climate change and his personal experiences seeing environmental impacts as an outdoorsman. He joined MCJ through an unusual progression from LP to advisor to executive chair to full-time Chairman and General Partner, and has architected the fund's institutional structure while designing a community-centric diligence model that taps MCJ's 4,000+ member network for domain expertise rather than relying solely on the partners' generalist backgrounds.
