Infrastructure for the AI Era

Explore our portfolio
Thesis
We build infrastructure that makes AI systems accountable, insurable, and enterprise-ready.

Not exits — trajectories.
Not speed — inevitability.

Patient Capital

We optimize for decade-scale impact over quarterly returns. The hardest problems require the longest arcs.

Deep Governance

Every product we build embeds accountability at the protocol layer. Permission is not proof.

Long Horizons

We're building for the world where autonomous agents are ubiquitous. That world is arriving faster than the infrastructure to govern it.
