Gigascale Capital
Gigascale Capital was founded in 2009 by Mike Schroepfer, then an angel investor who formalized his activity while still serving as CTO of what became Meta. Co-founder Ian Hogarth joined early, bringing his own track record from Songkick. The firm originally had a broader tech mandate but narrowed to climate around 2019, repositioning as a specialist in decarbonization. It operates from Palo Alto with a West Coast venture sensibility wired into deep-tech problem sets. The firm targets pre-seed through Series A companies across energy, transportation, agriculture, and carbon removal. Gigascale looks for technical founders solving measurable emissions problems — spanning lithium extraction, alternative cement, electric aviation, and methane monitoring. Publicly known positions include Heirloom Carbon, a direct-air-capture company; Pachama, a forest-carbon verification platform; and ZeroAvia, a hydrogen-electric aviation developer. The firm typically writes initial checks under $5 million and reserves for follow-on, occasionally participating in larger syndicated rounds alongside climate-native funds like Breakthrough Energy Ventures. Schroepfer left Meta in 2022, transitioning Gigascale from a part-time angel vehicle into a full-time investment platform. The firm has quietly backed over 30 companies, with a reported climate portfolio that more than doubled between 2021 and 2023 (per the firm's official communications, 2023). Headcount remains small, consistent with a concentrated partnership model rather than a multi-strategy manager. The firm has not announced dedicated side vehicles, though Schroepfer's personal philanthropic commitments to climate — including a large unrestricted grant to the Climate and Clean Energy program at Stanford — run parallel to the investment activity. Gigascale's structural differentiator is its operator-from-scale network. Unlike pure-finance VCs, the partnership's hiring and technical assessment is shaped by Schroepfer's experience managing tens of thousands of engineers and running one of the world's largest private compute infrastructures. That vantage allows Gigascale to diligence hard-tech companies with a level of technical depth uncommon at its check size. The firm also benefits from a latent LP base of retired Silicon Valley operators who prioritize emissions impact over pure IRR, creating a fund dynamic closer to a flexible project-finance vehicle than a traditional venture fund.

Frequently asked questions
Who makes investment decisions at Gigascale Capital?
Mike Schroepfer and Ian Hogarth drive all investment decisions as Managing Partners. Schroepfer's technical authority, built over a decade as CTO of Meta, anchors the firm's diligence on hard-science companies. The partnership remains small by design, with no junior investment committee — founders get partner-level engagement from first meeting through portfolio support.
How is Gigascale Capital different from other early-stage climate funds?
The firm's edge is technical operator diligence rather than financial engineering. Schroepfer's experience running Meta's infrastructure gives the partnership direct credibility with founders tackling compute-heavy, hardware-intensive climate problems. Most early-stage climate funds come from policy, finance, or clean-energy development backgrounds — Gigascale evaluates startups the way a senior technical executive would assess a moonshot engineering project.
What investment stages does Gigascale Capital target?
The firm focuses on pre-seed through Series A, typically writing initial checks under $5 million. It reserves capital for follow-on rounds and occasionally participates in larger syndicated deals when a portfolio company reaches commercial scale. The stage appetite is driven by the firm's conviction that the biggest emissions impact comes from getting physics-proven innovations to first commercial deployment.
Which sectors does Gigascale Capital explicitly invest in?
Gigascale concentrates on sectors with hard-to-abate emissions: energy, transportation, heavy industry, agriculture, and carbon removal. Within those, the firm has backed direct-air-capture, green cement, electric aviation, lithium extraction, and forest-carbon monitoring. It avoids pure-play software without a physical-world emissions linkage and has not invested in consumer-facing climate apps.
Does Gigascale Capital co-invest alongside other climate funds?
Yes — Gigascale routinely co-invests alongside climate-native funds like Breakthrough Energy Ventures, Lowercarbon Capital, and Chris Sacca's Lowercarbon Capital. Because the firm's check size and technical network are complementary to larger infrastructure-stage investors, syndicated rounds are common. The firm's operators-as-LPs model also means portfolio companies often get direct access to former CTOs and engineering leaders from the Meta and Stripe ecosystems.
How did Gigascale Capital's climate focus evolve?
The firm started in 2009 as a generalist tech angel vehicle but narrowed emphatically to climate around 2019. Schroepfer has cited the 2018 IPCC report as a turning point — after which the partnership decided to reserve substantially all new capital for decarbonization companies. The transition was complete by the time Schroepfer left his Meta CTO role in 2022 to run the firm full-time.
What is the firm's posture on follow-on investment?
Gigascale reserves capital for follow-on rounds, signaling conviction beyond the initial check. The firm has stated it intends to support portfolio companies through the critical first-commercial-deployment phase, which in hard-tech can require multiple financing rounds before positive unit economics emerge. Reserve allocation varies by company but is a deliberate part of fund construction rather than an ad-hoc decision.
