Gigascale Capital Closes $250 Million Fund Targeting Energy, Infrastructure and Industrial Technology Startups

Gigascale Capital has closed its first institutional fund with $250 million in commitments, providing fresh capital to back early-stage companies developing energy, manufacturing and infrastructure technologies aimed at modernizing the physical systems that underpin the economy.

Founded in 2023 by former Meta Chief Technology Officer Mike Schroepfer, the venture firm has already invested in more than 25 startups focused on clean energy, advanced manufacturing, grid infrastructure and physical AI. The new fund formalizes and expands that strategy, with an emphasis on technologies that can achieve widespread adoption through cost, performance and operational advantages rather than relying solely on sustainability mandates.

Gigascale’s investment thesis centers on what it describes as the rebuilding of the physical economy. The firm argues that accelerating electrification, industrial reshoring, AI deployment and increasingly severe weather events are exposing limitations in energy, manufacturing and infrastructure systems designed for a different era.

Rather than focusing narrowly on climate technologies, Gigascale is targeting businesses that address operational bottlenecks in energy production, industrial capacity and infrastructure deployment. Areas of interest include grid modernization, energy supply chains, advanced materials, manufacturing technologies and AI applications that improve the design, production and operation of physical systems.

“I’ve spent my career building technology that removes constraints,” Schroepfer said. “The companies we back win because they’re cheaper, faster, and more reliable. That’s how adoption scales.”

The fund reflects a broader shift within climate-focused venture investing toward commercialization and deployment. Investors are increasingly prioritizing technologies that can demonstrate tangible economic benefits alongside environmental impact, particularly as industries seek practical solutions to growing power demand, supply-chain challenges and infrastructure constraints.

Gigascale’s portfolio includes a range of companies addressing those challenges. Heron Power, founded by former Tesla executive Drew Baglino, is developing industrial power electronics. Solcoa is building a domestic rare-earth supply chain, while Radiant is working toward commercial deployment of nuclear microreactors. Other portfolio companies include fusion energy developer Xcimer Energy, baseload power provider Arbor Energy, AI chipmaker Fractile, carbon utilization company Dioxycle and food waste technology company Mill.

Several of those businesses have recently reached important operational milestones. Xcimer achieved first light on its commercial fusion laser system in late 2025, Arbor signed an agreement to supply up to 5 gigawatts of zero-emission power for data centers, and Fractile announced a major expansion of chip manufacturing capacity aimed at supporting AI workloads without proportional increases in energy consumption.

Gigascale’s leadership believes the biggest opportunities increasingly sit at the intersection of hardware, software and operational deployment. That focus has led the firm to invest in businesses combining physical infrastructure with artificial intelligence, automation and advanced manufacturing capabilities.

General Partner Victoria Beasley said recent advances in cost curves, deployment speed and manufacturing capabilities are creating a more favorable environment for industrial and energy startups than existed during previous clean technology investment cycles.

Beyond providing capital, Gigascale says it works closely with portfolio companies on recruiting, customer acquisition and commercialization strategies. The firm views the period between successful prototype development and large-scale deployment as one of the most significant challenges facing deep-tech startups and has structured its investment approach around helping founders navigate that transition.

With the new fund in place, Gigascale plans to continue investing in technologies that address critical infrastructure and industrial capacity constraints while supporting founders through the operational challenges of scaling complex physical systems.
