ONEOC
ONEOC (California) receives grants from 109 organizations whose IRS filings report $32,180,136 to it, the largest being Greater Horizons ($9,172,976). 54 of them have funded it in more than one year, and 52% of the money arrives through donor-advised or pass-through sponsors rather than from an institution directly. ONEOC administers funds for other donors, so those contributions arrive into funds it holds rather than supporting a program it runs itself.
Hosts funds for others
ONEOC administers funds on behalf of other donors. The grants recorded as coming in are contributions into those funds, so they count custody rather than support for a programONEOC runs itself. This page therefore states the flows and does not draw the comparisons it would draw for an operating charity: concentration, funder retention, grant dependency and the peer field are all left out, because each of them would read a vehicle as if it were a program.

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.
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: 2017 17% · 2018 12% · 2019 7% · 2020 18% · 2021 34% · 2022 11% · 2023 34% · 2024 37%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 5 of the last 8 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 22 funders to 40 funders, grant income fell $5.5M → $2.8M.
23 of 109 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 52% 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: $664k from one payer (the same organization on both sides, largest Oneoc). These are real filings, and they are not money ONEOC raised.
From the IRS filings of ONEOC’s funders (the co-funder graph). Top 30 of 109 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.
Where its funders are
52% of ONEOC'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 $15M that is directly attributable, 91% of it comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $17M arriving through sponsors registered in 12 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 109 funders put you typical among the 400 organizations that share them.
