San Diego Foundation Funder Map 2026
TLDR
San Diego County has a concentrated foundation community where a handful of funders shape most regional giving. This map pulls 990-PF distributions for those funders so your prospect list reflects what they actually fund — not just stated priorities.
Why This Map Exists
San Diego County hosts roughly 14,000 registered nonprofits and a foundation community where the top 20 funders distribute the bulk of regional giving. Because the funder pool is concentrated, an off-target LOI consumes a disproportionate share of prospecting capacity. Targeting precision matters more here than in larger metros.
This map shows what each foundation has actually funded over the last three years, paired with stated priorities, so LOI capacity goes where it converts.
