About
Gigascale Capital is an early-stage venture capital firm focused on climate technology, founded in 2023 by Mike Schroepfer, the former Chief Technology Officer of Meta 12. The firm announced its $250 million Fund I on June 1, 2026 — its first fund backed by outside institutional investors 13.
Gigascale’s thesis centers on what it calls “rebuilding the physical economy” — backing companies addressing acute constraints in clean energy, grid infrastructure, automation, critical minerals, and supply chains, particularly to meet rising power demand from AI and electrification 13. The firm positions itself as backing technologies that win on cost and performance first, with climate impact as a downstream consequence of adoption at scale 1.
The General Partner is Victoria Beasley, who works alongside founder Mike Schroepfer 3. Prior to the institutional Fund I, Gigascale invested as a personal vehicle for Schroepfer beginning in 2023 and has already built a portfolio of more than 25 companies 3.
Stated Thesis
Gigascale publicly describes its focus as backing companies “rebuilding the physical economy for climate impact” 1. In the announcement of Fund I, Schroepfer framed the thesis as:
“Climate impact won’t come from asking the world to adopt worse systems for virtuous reasons. It comes when a different technical approach makes the cleaner system also simpler, more scalable, and cost competitive.” 3
The firm explicitly targets areas where supply constraints are “most acute” — clean energy generation, grid infrastructure, critical materials, and the supply chains that connect them 13.
Inferred Thesis
Based on the publicly disclosed portfolio (sample size: small — only a subset of 25+ portfolio companies disclosed):
- Sector concentration: Heavy concentration in energy generation (fusion, nuclear, baseload power) and grid/power electronics. Disclosed names include Commonwealth Fusion Systems and Xcimer (fusion), Radiant (small modular nuclear), Arbor Energy (clean baseload power), Heron Power (industrial power electronics), Form Energy (long-duration storage), Dioxycle (sustainable chemicals), and Mill (consumer waste/circular) 112.
- Stage: Early-stage focused (seed and Series A), per firm self-description 4.
- Founder profile: Strong preference for technical operators from at-scale energy/hardware companies. Examples include Drew Baglino (former SVP Powertrain & Energy at Tesla, now at Heron Power) and Hooman Nezhad (Thiel Fellow building domestic rare-earth supply chain at Solcoa) 1.
- Geographic focus: US-based deep-tech climate companies, with founders drawn from Tesla, national labs, and similar institutions 1.
Note: Gigascale published a partial portfolio list. A complete inferred-thesis breakdown will be possible once more of the 25+ portfolio companies are publicly disclosed.

In Their Own Words
“Climate impact won’t come from asking the world to adopt worse systems for virtuous reasons. It comes when a different technical approach makes the cleaner system also simpler, more scalable, and cost competitive.” — Mike Schroepfer, Founder, in the Fund I announcement 3
“The world needs more power, more resilient supply chains, more critical materials, and better infrastructure. In many cases, the question for the best companies is no longer whether demand exists. It’s how fast they can supply it.” — Mike Schroepfer 3
“Solar went from 40 gigawatts a year to 600 in a decade because it got cheaper, not because it got more virtuous.” — Mike Schroepfer, on the firm’s adoption-first thesis 1
