Some climate funds chase software margins; Voyager Ventures goes after the base layer of the economy itself. Launched in 2021 by two deeply experienced climate investors, the firm backs early-stage companies in energy, materials and industrial technology that it sees as foundational to durable economic growth — and a meaningful route to startup funding for founders working on decarbonisation's hardest problems. With offices in San Francisco, New York and London, Voyager now manages $475 million across three funds.
Our thesis: foundational industries of the future
Voyager invests in frontier energy and industrial technology companies it calls "foundational to enduring abundance at global scale" — technologies that modernise the base layer of the economy across energy production and distribution, advanced manufacturing, critical materials, physical AI and compute. The bet is that electrification, automation, AI and advanced manufacturing are converging into durable prosperity, and that technology which simply performs better will win markets while decarbonising them.
Sectors and stages: six decarbonisation themes
Fund II invests across six sectors: Energy + Efficiency (generation, storage and smarter use), Materials Production (core materials made with speed and precision, domestically and at scale), Software + AI (intelligence layered onto physical systems), Mobility (air, land, sea and the data layers between), Built Environment (software and hardware for long-lived assets), and Carbon Management (measure, capture, reuse and remove carbon). The firm is explicitly early-stage, partnering with founders across North America and Europe, in both frontier and digital technology.
Fund size and cheque size
Voyager announced its $275 million Fund II in early 2026, bringing total assets under management to $475 million across three funds. The firm describes itself as an early-stage investor but publishes no standard cheque range — it is not publicly disclosed.
Notable portfolio
Fund II's early investments include ENAPI, Leeta Materials and Electroflow Technologies. The broader portfolio spans Allie, Anthro Energy, Arbor Energy, Astro Mechanica, Spore.Bio (rapid bacterial diagnostics), Endurance Energy (subsea geothermal for zero-emissions baseload power) and NewOrbit (satellites for very low Earth orbit) — plus a stealth bet on computing with light.
Partners
Voyager was founded by General Partners Sarah Sclarsic and Sierra Peterson, who together bring more than 30 years of company-building, operating and policy experience. Sclarsic researched synthetic biology at MIT, helped build Modern Meadow as a founding-team member and co-founded the sustainable-transport unicorn Getaround. Peterson designed carbon markets at the International Energy Agency, shaped energy and industrial policy in the Obama White House, and later led corporate development teams that financed more than $3 billion in energy projects across North America.
Programs, credits and perks
Voyager runs no public accelerator and publishes no formal perks programme. Its value-add is the partners' operating and policy depth — company-building, carbon-market design and industrial-policy experience — plus networks across energy, materials and mobility.
How to apply for funding
Voyager publishes no public application form or open pitch portal. Founders are directed to the firm's website at voyagervc.com to make contact with the team.
Why it matters for founders
If you are building in energy, materials or industrial decarbonisation, Voyager pairs early-stage capital with partners who have actually built companies and shaped the policies your market depends on — a rare combination at the frontier-tech end of climate investing.
