## Questions

### Who runs investment decisions at Lowercarbon Capital?

Chris Sacca, Crystal Sacca, and Clay Dumas lead the partnership. Chris Sacca previously built Lowercase Capital, where he made concentrated early-stage bets on Twitter, Uber, and Instagram. The team operates with a flat structure, and Sacca has publicly stated they avoid building layers of non-investment staff.

### How does Lowercarbon source its deals?

The firm draws heavily from Sacca's network and its reputation as a non-dilutive, founder-friendly climate investor. It proactively identifies scientists and engineers emerging from labs and research institutions. Lowercarbon also accepts inbound applications, and publicly emphasizes that it reads every pitch deck submitted through its website.

### Does Lowercarbon participate in fund commitments or only direct deals?

Lowercarbon primarily makes direct investments in early-stage startups. However, it structures itself with the flexibility to make follow-on investments into later rounds within its own portfolio. There is no public record of the firm acting as a traditional limited partner in other venture funds.

### Is Lowercarbon related to Sacca's prior firm, Lowercase Capital?

Lowercarbon Capital is a separate legal entity with a completely distinct investment mandate from Lowercase Capital. While Chris Sacca founded both, Lowercase focused on consumer internet and software. Lowercarbon exclusively pursues climate technology with a hard requirement that portfolio companies have the potential for gigaton-scale carbon reduction.

### What is Lowercarbon's known posture on co-investments alongside external partners?

Lowercarbon often leads rounds and does not publicly require co-investors on every deal. However, it has co-invested alongside generalist deep-tech funds and climate-specific allocators like Breakthrough Energy Ventures. The firm's large fund sizes give it the capacity to act as a sole institutional lead when it chooses.
