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.

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.

Seed San Diego typically writes initial checks between $250,000 and $750,000, seeking to lead or co-lead pre-seed and seed rounds. The portfolio is built around 25-to-35 positions per fund, with follow-on reserves allocated for roughly one-third of companies. The firm does not publicly disclose its target ownership percentage, but its check sizes and fund scale suggest it typically seeks meaningful minority stakes.

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.

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.
