The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 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 2022 to 2023, from $53M to $73M (+37%).
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.
Government-grant reliance: 2021 7% · 2022 1% · 2024 5%. Grants only. Government contracts and fees sit inside program revenue.
7% of THE BAY SCHOOL OF SAN FRANCISCO’s revenue is contributions — more earned-revenue than three-quarters of its peers (23% for the typical peer).

Who funds it, year by year

From the IRS filings of THE BAY SCHOOL OF SAN FRANCISCO’s funders (the co-funder graph). Top 30 of 55 funders by total. 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
THE BAY SCHOOL OF SAN FRANCISCO has a broad base — no single funder exceeds 14% of grant income, and it takes 4 funders to reach half.
the vertical line marks half of all grant income — 4 funders to its left
87% 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 THE BAY SCHOOL OF SAN FRANCISCO.
Largest funder’s share by year: 2017 32% · 2018 24% · 2019 26% · 2020 23% · 2021 27% · 2022 20% · 2023 28% — 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
47% of THE BAY SCHOOL OF SAN FRANCISCO's funders are still giving 3 years after their first grant; 69% 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 THE BAY SCHOOL OF SAN FRANCISCO'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 $1.9M that is directly attributable, 67% of it comes from funders outside California, across 17 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $9.9M arriving through sponsors registered in 13 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.
