Revenue, expenses and net assets — each indexed to 100 at its first filing year, so you read the trajectory, not the magnitude.
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 4 reported years ran a deficit.
The base broadened — 1 funders to 2 as grant income moved $1k → $8k.
1 of 7 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 1% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

In-state vs out-of-state, by year
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.
From the co-funder graph (funders backing at least two comparable organizations, shrunk for grantee count, donor-advised and mega-funds excluded) and the universe embeddings. A research starting point; overlap is association, not a guarantee of fit.
Nonprofits whose mission and program text most resemble this one, by semantic similarity over the universe of US filings — the closest peers, and often the clearest route to shared or prospective funders.

Share of support from the public (Schedule A) — the basis for its public-charity status.
Every figure is read directly from IRS Form 990 / 990-PF e-file XML — this organization’s own return for FY2024 (financials across 2021–2024), and the filings of 7funders that report grants to it. “On record” means captured in the filings we have parsed — a funder that does not e-file, or whose grant detail is not itemized, will not appear. Filings run roughly 12–24 months behind. view filing
