The program described on its FY2024 Form 990-PF.
The organization over time
Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2021 to 2022, from $44M to $38M (−13%).
Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.

Who funds it, year by year
2018 → 2023: the base broadened from 1 funder to 18 funders, grant income rose $2k → $438k.
7 of 28 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 32% 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 WETHERSFIELD 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.
How concentrated its funding is
WETHERSFIELD FOUNDATION INC has a broad base — no single funder exceeds 19% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
35% 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 WETHERSFIELD FOUNDATION INC.
Largest funder’s share by year: 2018 100% · 2019 88% · 2020 72% · 2021 44% · 2022 43% · 2023 57% — diversifying over time.
“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.
How long its funders stay
75% of WETHERSFIELD FOUNDATION INC's funders are still giving 3 years after their first grant; 57% 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. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
WETHERSFIELD FOUNDATION INC draws 66% of its grant income from funders outside New York, across 9 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $414k arriving through sponsors registered in 6 states is 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.
