$1,826,110 spent$116,850 earned by the program97% of program spendingThe goal of the Dolphin Youth Swim Fund is to provide a learn to swim opportunity for a child in San Francisco that does not have the economic resources to participate in a swim program. Our goal is to support these children in programs that are designed to go beyond just exposure to the water but start from the beginning and finish with achieving swimming competency. Our long term goal is to create partnerships with organizations that intend to offer learn to swim all the way to competency and provide financial scholarships to make this possible. In 2023 80 swimmers were provided swim instruction through funding provided by the Dolphin Youth Fund awards.

The organization over time
Each line starts at 100 in 2019, so what you read is the shape rather than the size: 150 means half as much again as 2019, 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 2024 to 2025, from $3.7M to $2.1M (−43%).
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.
61% of Dolphin Swimming and Boating Foundation’s revenue is contributions — more donation-reliant than the typical peer (18% for the typical peer).
Surplus & reserves

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
2019 → 2023: the base broadened from 1 funder to 5 funders, grant income rose $50 → $115k.
7 of 12 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 84% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

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
Dolphin Swimming and Boating Foundation leans on a few funders — its largest provides 30% of grant income and the top three 66%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
84% 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 Dolphin Swimming and Boating Foundation.
Largest funder’s share by year: 2019 100% · 2020 65% · 2021 46% · 2022 33% · 2023 37% — diversifying over time.
“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.
How long its funders stay
50% of Dolphin Swimming and Boating Foundation's funders are still giving 3 years after their first grant; 50% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
84% of Dolphin Swimming and Boating 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 $88k that is directly attributable, 86% of it comes from funders outside California, across 3 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $469k arriving through sponsors registered in 6 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.
