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. 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 $1.8M to $2.6M (+43%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
71% of COSLEY FOUNDATION INC’s revenue is contributions — more donation-reliant than the typical peer (63% for the typical peer).
Surplus & reserves

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 5 funders, grant income rose $15k → $154k.
8 of 19 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 81% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

How concentrated its funding is
COSLEY FOUNDATION INC leans on a few funders — its largest provides 55% of grant income and the top three 75%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
82% 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 COSLEY FOUNDATION INC.
Largest funder’s share by year: 2018 100% · 2019 61% · 2020 65% · 2021 36% · 2022 47% · 2023 70% — 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
71% of COSLEY FOUNDATION INC's funders are still giving 3 years after their first grant; 63% 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
81% of COSLEY FOUNDATION INC's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $205k that is directly attributable, 53% of it comes from funders outside Illinois, across 5 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $896k arriving through sponsors registered in 7 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.
