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.
The funding model — what share of revenue comes from contributions, programs, investments and other sources — and whether it's shifting.
100% of Clean Water Legacy’s revenue is contributions — more reliant on donations than three-quarters of its peers (86% for the typical peer).
Operating surplus or deficit each year, and months of liquidity in hand. 1 of the last 4 reported years ran a deficit.
Grant income rose $16k → $28k on a roughly flat funder count — a concentrated base.
5 of 10 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 68% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of Clean Water Legacy’s funders (the co-funder graph). Association, not causation.
Clean Water Legacy leans on a few funders — its largest provides 39% of grant income and the top three 67%; half comes from just 2 funders.

Largest funder’s share by year: 2017 100% · 2019 100% · 2020 100% · 2021 73% · 2022 45% · 2023 39% · 2024 63% · 2025 100% — broadly stable.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration.
17% of Clean Water Legacy's funders are still giving 3 years after their first grant; 40% 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.
Clean Water Legacy draws 90% of its grant income from funders outside South Dakota — its reputation reaches beyond the state, across 6 states in all.
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. Your 10 funders put you under-funded among the 400 organizations that share them.
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 2021–2024), and the filings of 10funders 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
