Angel Investors in San Diego (2026)

433 investors · 433 individual angels · 47% with verified email · 0 claimed profiles

San Diego has 433 investors in the Robynhood database, and its defining feature is life sciences: 84 in healthtech plus 42 in biotech gives 126 investors in health and bio, the second-strongest concentration after Boston relative to city size.

A genuine biotech cluster

The 42 biotech investors are more than Chicago, Miami or Seattle can offer despite each being a larger market. San Diego's pharmaceutical and genomics industry — Illumina, the Salk Institute, UCSD — produced them.

AI/ML at 64 increasingly overlaps with that group rather than competing, as computational biology pulls the two together.

Fintech at 40 is comparatively weak. This is not a market for financial products.

Reach and pace

203 of 433 have a verified email — 47%.

Life sciences investors move on longer timelines than software investors, and diligence is more technical. If your company is biotech or medtech, San Diego is worth more of your time than its size suggests. If it is not, the city is a lower priority than Los Angeles two hours north.
