Voyager Ventures is a San Francisco- and New York-based climate technology venture capital firm founded in 2021 by Sarah Sclarsic and Sierra Peterson, focused on early-stage investments in startups advancing global decarbonization across sectors like mobility, energy, materials, food, the built environment, industrial systems, analytics, and carbon management. With $200 million in assets under management across its inaugural $100 million Fund I (closed in 2022) and $100 million Select Fund I (closed in 2024), the firm invests primarily in pre-seed to Series A (and select follow-ons) in North America and Europe, aiming to support companies that can sequester or avert 500 million tonnes of CO2e per fund while delivering strong commercial returns. The portfolio includes around 50 investments with notable companies in areas like carbon-negative materials, trucking emissions reduction (Remora), energy efficiency AI (Ento Labs), last-mile logistics decarbonization (Packfleet), and manufacturing AI (Allie), backed by LPs such as founders from Lyft, Shopify, and Segment, emphasizing unit economics and scalable climate impact.
