Ex-Meta CTO Mike Schroepfer Launches $250M Climate Fund to Tackle Energy Shortages

TL;DR

• Mike Schroepfer, Meta’s former CTO, has turned his focus to climate tech and is backing Gigascale Capital, a climate venture firm he launched in 2023.
• Gigascale is designed to fund startups building scalable solutions in areas such as clean energy, industrial decarbonization, alternative materials, and methane reduction.
• Schroepfer’s climate strategy combines investing with philanthropy, including initiatives like Carbon to Sea and Outlier Projects.

Mike Schroepfer’s shift from Meta to climate tech

Mike Schroepfer, the former CTO of Meta, has spent the past several years steadily moving from big-tech infrastructure to climate-focused investing and philanthropy. He stepped away from his CTO role in 2021 to concentrate on climate change, while continuing as a senior fellow at Meta.

That transition helped lead to Gigascale Capital, the climate venture firm he unveiled in 2023 and now positions as a vehicle for backing companies with the potential to deliver climate impact at scale.

What Gigascale Capital is betting on

Gigascale is focused on early-stage climate technology companies, with an emphasis on businesses that can grow into venture-scale winners while also cutting emissions or reducing resource constraints. According to reporting on the firm’s launch, its areas of interest include decarbonizing buildings and industrial processes such as cement and steel, as well as alternative food systems.

Other reported investment themes include fusion energy, landfill emissions reduction, and methane mitigation from livestock. Gigascale’s site describes the firm as founded in 2023 to support “the next trillion-dollar companies delivering climate impact at scale,” underscoring its aim to pair large commercial returns with climate outcomes.

Why the fund matters now

Schroepfer has argued that climate tech is entering a more decisive phase, with growing demand for solutions that address energy and material shortages while remaining economically viable. That framing reflects a broader shift in the sector: investors are increasingly looking for technologies that can scale in the real economy, not just pilot projects or policy-dependent concepts.

In that sense, Gigascale is being positioned less as a traditional impact fund and more as a bet on climate infrastructure, manufacturing, and energy systems that can compete in mainstream markets.

Schroepfer’s broader climate portfolio

Gigascale is only one part of Schroepfer’s climate activity. He also launched Carbon to Sea, a nonprofit effort focused on ocean alkalinity enhancement as a carbon-sequestration approach, and later Outlier Projects, which funds research teams working on greenhouse-gas removal, glacier stabilization, and solar geoengineering.

That mix suggests Schroepfer is pursuing a two-track strategy: backing near-term commercial startups through Gigascale while also funding longer-horizon research that could shape the next generation of climate solutions.

The fundraising angle

The specific article prompt refers to a $250 million climate fund, but the sources available here do not independently confirm that exact amount. CNBC reported at Gigascale’s launch that Schroepfer was funding the firm through his family office and described the commitment as “serious,” but it did not disclose a precise fund size.

If the $250 million figure is current, it likely reflects a later fundraising milestone or updated reporting beyond the launch coverage in the available sources. Based on the sources reviewed, the safest verified takeaway is that Gigascale is a substantial self-backed climate investment platform, not that its size is definitively established at $250 million.

What to watch next

The biggest question is whether Gigascale can turn its thesis into a repeatable pipeline of companies that solve hard climate problems and scale commercially. Schroepfer’s track record at Meta gives him credibility in operating and scaling technical systems, but the climate market will ultimately judge the fund on startup performance, follow-on capital, and whether its portfolio can deliver both returns and measurable climate impact.
