## Questions

### What stage does Phi-X Capital target?

Phi-X Capital focuses on early-stage venture investments, specifically seed and startup rounds. This places it at the earliest institutional entry point, often participating in a company's first priced equity round or pre-seed convertible note financings. The firm does not publicly disclose later-stage or growth-equity activities.

### What is Phi-X Capital's known posture on co-investments alongside external GPs?

No co-investment program or club-deal structure is publicly documented for Phi-X Capital. The firm's low public profile and early-stage focus suggest it invests directly and does not operate a formal co-investment platform alongside other institutional investors.
