Starshot Capital
Jeremy Brewer and Sam Levac-Levey's Starshot Capital invests early-stage decarbonization capital from Halifax.
Starshot Capital
Starshot Capital was founded by Jeremy Brewer and Sam Levac-Levey, two former operators who met inside Google and Facebook's alumni investment ecosystems. Brewer previously led investment vehicles for those communities while doing venture and private equity work for a large Canadian family office; Levac-Levey brought manufacturing experience from SpaceX and Tesla alongside fuselage design work at Lilium. The pair also co-founded Work on Climate, a technical climate community that claims to be the largest in the world. That community serves as a proprietary deal-flow engine for the firm, blending operator DNA with climate-specific founder networks. The firm writes early-stage checks across hardware and software that directly enable decarbonization. Its portfolio spans agricultural methane reduction (Rumin8), industrial AI for energy efficiency (Phaidra, which partnered with NVIDIA), and grid transformation technology. A co-investor in Ecolectro — a green hydrogen startup featured in TechCrunch — Starshot also backs Miraterra, a soil-carbon measurement company that acquired Trace Genomics. The geographic footprint concentrates on North American and Australian startups, though the firm's partner bench ties it to European and Asian supply chains as well. The current team lists seven professionals, including Managing Partner Brewer, Founding Partner Levac-Levey, and four-decade sustainability operator Jeff Seabright, who previously served as Chief Sustainability Officer at Unilever and co-chaired the Consumer Goods Forum's Sustainability Committee. Venture Partner Zoe Samuel co-created Alphabet's internal climate community Anthropocene before joining. No AUM or total deployment figure is publicly disclosed, and the firm has not announced a formal fund close. As of May 2026, the management structure remains founder-led with no external GP succession indicated. What separates Starshot from other early-stage climate vehicles is its explicit dependence on a volunteer-run technical community for origination. Brewer and Levac-Levey built Work on Climate before launching the fund, meaning the firm's thesis predates its capital base. This architecture positions Starshot less as a passive LP and more as a talent-and-expertise syndicate that writes first checks into companies its principals have often already advised.

Frequently asked questions
How does Starshot Capital source deal flow?
Starshot sources primarily through Work on Climate, a technical climate community founded by Brewer and Levac-Levey that claims to be the largest in the world. Venture Partner Zoe Samuel also co-created Alphabet's internal climate community Anthropocene, now over 4,000 members. This dual-community model gives the firm access to founder referrals, technical due-diligence capacity, and early looks at startups spinning out of large technology companies.
What is the relationship between Starshot Capital and Work on Climate?
Work on Climate is a separate volunteer-run community, not a legal subsidiary of Starshot. Jeremy Brewer chairs its board and Sam Levac-Levey is a founding member and former Vice Chair. Starshot does not own Work on Climate, but the community functions as an informal origination and screening layer for the firm's investment pipeline.
Does Starshot Capital participate in fund commitments or only direct deals?
Based on available disclosures, Starshot appears to invest exclusively in direct early-stage equity deals. The firm's team composition — predominantly operators, not fund-picking allocators — and its portfolio of named portfolio companies like Rumin8, Phaidra, and Ecolectro suggest a direct-investment posture. No fund-of-fund commitments have been publicly identified.
What investment stages does Starshot Capital target?
Starshot targets early-stage startups, specifically at the Seed and Series A stages. Its portfolio includes companies like Rumin8, which raised a seed round for livestock methane reduction, and Phaidra, an AI-for-industrial-controls company that partnered with NVIDIA while still scaling its initial deployments. The firm's operator-heavy background aligns with the hands-on requirements of pre-revenue and early-commercialization companies.
Who runs investment decisions at Starshot Capital?
Managing Partner Jeremy Brewer leads investment decisions. He previously ran investment vehicles for Google and Facebook alumni and did venture capital work for a large Canadian family office. Founding Partner Sam Levac-Levey and Partner Jeff Seabright sit alongside him on the investment committee, with Principal Nicholas Gould handling due diligence on hydrogen and industrial-technology deals.
Which sectors does Starshot Capital explicitly target?
Starshot invests exclusively in decarbonization. Within that mandate, the firm covers agricultural methane (Rumin8), industrial AI and energy efficiency (Phaidra), green hydrogen (Ecolectro), grid modernization, and soil-carbon measurement (Miraterra). The firm has not disclosed investments in consumer climate apps, carbon offsets, or compliance-heavy regulatory technology.
What is Starshot Capital's known posture on co-investments alongside external GPs?
Starshot's model relies on co-investment rather than proprietary deal sourcing. The firm's communities (Work on Climate, Anthropocene) surface deals that often syndicate with other early-stage climate investors. Portfolio company Ecolectro, for example, was also covered by TechCrunch in the context of a broader climate fundraise, indicating Starshot participates in competitive rounds rather than leading them exclusively.
