## Questions

### How does Ironfire source deal flow, and what differentiates its access?

The firm sources primarily from the Bay Area technology ecosystem. Its principal structural differentiator is a limited-partner base that includes Asian family offices and technology operators, giving Ironfire portfolio companies direct go-to-market pathways into Asia-Pacific — a distribution channel most US-only seed funds cannot offer.

### Does Ironfire Ventures participate in fund commitments or only direct deals?

Ironfire invests directly into operating companies. The firm does not operate a fund-of-funds strategy, nor does it publicly allocate to other venture capital managers. Its capital deploys exclusively into portfolio-company equity at the seed stage.

### What sectors does Ironfire explicitly avoid?

Ironfire has historically concentrated on enterprise software, applied AI, and deep tech. It has not been active in life sciences, consumer apps, climate hardware, or crypto, and its public portfolio does not indicate any negative screening beyond sector focus. These exclusions reflect mandate discipline rather than an explicit negative list.
