fund

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.

Ian Brooke

Ian Brooke

CEO · Astro Mechanica

Ian Brooke is the founder and CEO of Astro Mechanica, a San Francisco-based aerospace startup backed by Y Combinator (W24) and investors including United Airlines Ventures, pioneering the turboelectric adaptive engine—a revolutionary hybrid-electric jet propulsion system that maintains peak efficiency across all speeds from takeoff to Mach 3+, enabling sustainable supersonic commercial flight, long-range cargo, national defense applications, and even cost-effective orbital launches via air-breathing stages. A lifelong pilot who began flying at age 16 and inspired by fighter jets like the F-15, Brooke—a University of Colorado Boulder physics graduate and serial entrepreneur with a prior successful venture—launched Astro Mechanica in 2021 to disrupt a stagnant industry, rapidly prototyping engines in months using off-the-shelf components and raising significant funding (including $27M+ rounds) to challenge incumbents like Boeing and GE. Passionately advocating for a new "Turboelectric Age" of abundant, point-to-point global mobility—shrinking transcontinental trips to hours at economy fares while slashing fuel use—he drives milestones like supersonic demonstrations targeted for 2025 and vertical integration toward building the next-generation aerospace titan.
