The Firm
We back the operators rewriting what the physical world can do.
Mavis Collective is a growth equity firm investing minority capital into late-stage, pre-IPO companies at the frontier of science and industry. We work with founders who have moved past invention and into the hard, durable work of scaling.
Our mandate is concentrated, our diligence is patient, and our partnership is long. We aim to be the most thoughtful capital on the cap table — not the loudest.
Where we invest

Five interlocking frontiers where capital, science, and national interest converge.
Defense
Next-generation systems supporting national security and allied capability.

Fusion, advanced nuclear, grid, and the architecture of abundance.
Space
Launch, in-space infrastructure, and the commercialization of orbit.
Approach
A different shape of partnership.
