Prelude Ventures

Prelude Ventures LLC is a private venture capital firm based in San Francisco that invests in and supports early-stage startups focused on mitigating climate change. The firm operates as a specialist investor rather than a software or operating business, and its commercial role is to allocate capital, support portfolio companies, and manage investment vehicles. The firm manages capital exclusively for Simons family philanthropic entities, which makes its economic model different from a conventional broad-based fund manager raising institutional third-party capital. Its customers and counterparties are primarily founders seeking early-stage climate technology funding and the capital owners whose assets it manages. Value is created through thematic sourcing, investment selection, portfolio support, and long-term capital deployment into climate-related startups.
