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 2020 to 2021, from $6.0M to $6.9M (+14%).
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.
89% of PORTOLA VALLEY SCHOOLS FOUNDATION’s revenue is contributions — more donation-reliant than the typical peer (48% for the typical peer).

How concentrated its funding is
PORTOLA VALLEY SCHOOLS FOUNDATION leans on a few funders — its largest provides 36% of grant income and the top three 79%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
93% 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 PORTOLA VALLEY SCHOOLS FOUNDATION.
Largest funder’s share by year: 2017 48% · 2018 53% · 2019 49% · 2020 41% · 2021 61% · 2022 40% · 2023 39% — 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
67% of PORTOLA VALLEY SCHOOLS FOUNDATION's funders are still giving 3 years after their first grant; 85% 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
92% of PORTOLA VALLEY SCHOOLS 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 $267k that is directly attributable, 70% of it comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $3.2M arriving through sponsors registered in 11 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.
