Revenue, expenses and net assets — each indexed to 100 at its first filing year, so you read the trajectory, not the magnitude. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 5 reported years ran a deficit.
$20k from 1 funders in 2025, up from $26k and 3 in 2020.
2 of 4 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 15% 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.

Every figure is read directly from IRS Form 990 / 990-PF e-file XML — this organization’s own return for FY2024 (financials across 2020–2024), and the filings of 4funders 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
