Clean Energy Funds
Gigascale Capital Closed Its $250 Million Funding Round
Adam Harrie — June 1, 2026
Gigascale Capital closed its first Clean Energy Fund at $250 million, targeting early-stage companies rebuilding clean energy infrastructure, grid systems and advanced manufacturing. Founded in 2023 by former Meta CTO Mike Schroepfer, the fund has already backed more than 25 companies developing the energy and materials systems needed for a lower-carbon economy.
The fund's portfolio is already showing momentum. Xcimer Energy achieved first light on a commercial fusion laser system, Arbor Energy signed an agreement to deliver up to 5GW of zero-emission baseload power to US data centers and Dioxycle partnered with L’Oréal to convert captured CO₂ emissions into ethylene for plastic packaging.
Gigascale shows that the most durable climate progress is likely to come from technologies that compete on cost, performance and environmental impact.
