Gigascale Capital’s Bold Move in Climate Tech
In a significant development for the clean energy sector, Mike Schroepfer, the former CTO of Meta, has successfully closed Gigascale Capital’s inaugural institutional fund, raising $250 million. This fund aims to support more than 25 promising early-stage companies focused on advancing energy, materials, and infrastructure systems.
A Shift in Investment Strategy
Founded in 2023 and headquartered in Palo Alto, Gigascale Capital marks a pivotal transition from Schroepfer’s personal investments to institutional backing. This shift underscores the growing interest and confidence in deep-tech climate investing, even amidst a reported 11% decline in early-stage climate venture capital participation in 2025.
Climate Tech’s Growing Market
According to Sightline Climate, global climate tech VC investment soared to $40.5 billion in 2025, reflecting an 8% year-on-year increase. The core of Gigascale’s investment philosophy hinges on the understanding that climate solutions become viable not purely from virtue but through reducing costs. Schroepfer emphasized, “The pattern is always the same: cost curves bend, markets scale, and a better alternative makes the old way obsolete.”
Innovative Investments
Among the portfolio companies, Radiant is pioneering commercial deployment of nuclear microreactor technology, while Xcimer Energy has achieved a milestone with the world’s first private-sector electron-beam excimer laser. Additionally, Fractile raised $220 million to enhance AI inference chip production, showcasing the dynamic nature of the sector.
Competitive Landscape
Gigascale now finds itself in direct competition with well-resourced firms such as Lowercarbon Capital and Breakthrough Energy Ventures, both managing over $2 billion in assets. However, Gigascale’s focus is distinctly on early-stage, US-based ventures, designed to bridge the crucial gap between prototype and deployment—an area where many deep-tech firms struggle.
The Future of Climate Tech
As the global climate tech market is projected to reach $115.4 billion by 2030, the success of firms like Gigascale will be pivotal in determining the future landscape of climate investments. Co-General Partner Victoria Beasley remarked, “What’s different now isn’t narrative. Cost curves have moved; founders can build and deploy faster than ever.” The question remains whether Gigascale can replicate its founder’s operational expertise across a diverse portfolio of companies.
