## Questions

### Who leads investment decisions at Seed San Diego?

The firm's investment decisions are driven by its founding partners, whose identities are a matter of public record through SEC filings and portfolio company board positions. As a lean team operating from a single office, the general partners share deal-sourcing and investment-committee responsibilities without a separate CIO layer. The firm has not publicly disclosed succession plans.

### What is Seed San Diego's geographic mandate?

The firm invests almost exclusively within a 100-mile radius of its Solana Beach office, concentrating on startups in San Diego County and, to a lesser extent, Orange County and Los Angeles. This constraint is intentional — the firm views physical proximity as a material advantage for board participation, local-network reference checks, and introductions to the region's corporate executives.

### Does Seed San Diego invest outside of software and deep tech?

While Seed San Diego is a generalist fund, its historical portfolio skews heavily toward enterprise software, AI/ML, digital health, and industrial technology — sectors aligned with San Diego's research university strengths and defense-contractor ecosystem. The firm has not publicly identified any sectors it explicitly avoids, but consumer internet and capital-intensive hardware have not historically been core areas of activity.

### How is the firm's capital base structured?

Seed San Diego raises traditional closed-end venture funds from limited partners that include family offices, high-net-worth individuals, and a small number of institutional investors. Its most recent vehicle, Seed San Diego III, targeted $50 million per a December 2024 SEC filing. The firm does not operate a rolling fund, a publicly listed vehicle, or a permanent-capital structure, and it has not disclosed formation of a co-investment vehicle separate from the main fund.
