What San Diego County Prosperity Foundation does
Mission
The mission of the San Diego County Prosperity Foundation is to support various charitable activities that promote individual & societal prosperity locally and beyond.
As stated on its FY2024 Form 990.
Programs
On its FY2024 return the organization reported a significant change in how it conducts a program.
In early 2024, the Ukraine Freedom Project (a project for which the organization previously served as a fiscal sponsor since 2022) obtained an independent 501c3 exemption. Accordingly, it ceased using the San Diego County Prosperity Foundation as its fiscal sponsor in 2024.
Its own explanation, from Schedule O of that return (Part III, line 3).
Carols by Candlelight is a fundraiser that takes place in San Diego County each year, raising funds for Rady Childrens Hospital by collecting sponsorships, ticket ssales and auction revenue. Funds donated to Rady Childrens Hospital Foundation totaled $50,764

The organization over time
Each line starts at 100 in 2022, so what you read is the shape rather than the size: 150 means half as much again as 2022, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2023 to 2024, from $235k to $59k (−75%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
195% of San Diego County Prosperity Foundation’s revenue is contributions — more reliant on donations than three-quarters of its peers (97% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 1 of the last 3 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2022 → 2023: the base broadened from 4 funders to 5 funders, grant income rose $28k → $115k.
3 of 7 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 91% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of San Diego County Prosperity Foundation’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
San Diego County Prosperity Foundation leans on a few funders — its largest provides 70% of grant income and the top three 91%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
91% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund San Diego County Prosperity Foundation.
Largest funder’s share by year: 2022 70% · 2023 88% — growing more concentrated.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Where its funders are
91% of San Diego County Prosperity Foundation's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $13k that is directly attributable, 100% of it comes from funders outside California, across 4 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $131k arriving through sponsors registered in 3 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
