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.
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.
97% of THE PRIMARY SCHOOL’s revenue is contributions — more reliant on donations than three-quarters of its peers (48% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 4 reported years ran a deficit.

Who funds it, year by year
2021 → 2023: the base broadened from 3 funders to 6 funders, grant income rose $705k → $13M.
5 of 10 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 96% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $5.0M from 2 payers (the payer shares this organization's board, largest The Primary School - East Palo Alto). These are real filings, and they are not money THE PRIMARY SCHOOL raised.
From the IRS filings of THE PRIMARY SCHOOL’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
THE PRIMARY SCHOOL leans on a few funders — its largest provides 95% of grant income and the top three 99%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
98% 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 PRIMARY SCHOOL.
Largest funder’s share by year: 2021 85% · 2022 67% · 2023 94% — 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
96% of THE PRIMARY SCHOOL'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 $1.4M that is directly attributable, 100% of it comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $32M arriving through sponsors registered in 5 statesis 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.
Funders to approach
Grantmakers that don’t fund you yet, surfaced two ways: they back organizations that share your funders, or their grantees resemble your mission. The ones both signals agree on come first. Your 10 funders put you under-funded among the 400 organizations that share them.
