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.
Who funds it, year by year
2017 → 2023: the base held at 4 funders, grant income rose $364k → $376k.
1 of 7 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 98% 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 THE WINDHAM FOUNDATION INC’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.

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 WINDHAM FOUNDATION INC.
Largest funder’s share by year: 2017 93% · 2018 100% · 2019 100% · 2020 100% · 2021 100% · 2022 100% · 2023 93% — broadly stable.
“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

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $2.8M arriving through sponsors registered in 1 stateis 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.
