## Questions

### What is Riot Ventures' investment focus?

Riot Ventures invests exclusively in what it calls the modernization of the physical world. Portfolio clusters include orbital space defense, autonomous maritime and rail systems, AI-powered military pilots, advanced nuclear reactors, construction robotics, and enterprise AI. It avoids pure software plays and consumer internet in favor of hard-tech businesses tied to critical infrastructure and national security.

### Does Riot Ventures lead rounds, and what check sizes does it write?

The firm states it can write checks up to $100 million. Its concentrated portfolio and the maturity of holdings like Shield AI and True Anomaly suggest it leads or co-leads rounds and reserves significant capital for follow-on investments, functioning more like a concentrated growth-stage operator than a seed-stage spray investor.

### How does Riot Ventures source its defense and space deals?

Riot Ventures combines deep ties inside the US defense-industrial base with a West Coast venture posture. Its portfolio companies like True Anomaly, Shield AI, and Blue Water Autonomy operate at the intersection of Silicon Valley engineering talent and Department of Defense procurement cycles, implying sourcing through technical-founder networks, former military operators, and existing portfolio referrals.
