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 2018 to 2019, from $509k to $583k (+15%).
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.
Government-grant reliance: 2020 18% · 2021 6% · 2022 12% · 2023 12% · 2024 1%. Grants only. Government contracts and fees sit inside program revenue.
39% of FOUR MOUNDS FOUNDATION’s revenue is contributions — about as donation-reliant as the typical peer (63% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 8 reported years ran a deficit.

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.
The chief executive listed changed between the FY2018 and FY2019 filings.

How concentrated its funding is
FOUR MOUNDS FOUNDATION leans on a few funders — its largest provides 51% of grant income and the top three 74%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
41% 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 FOUR MOUNDS FOUNDATION.
Largest funder’s share by year: 2017 54% · 2018 24% · 2019 86% · 2020 57% · 2021 30% · 2022 80% · 2023 76% — growing more concentrated.
“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
50% of FOUR MOUNDS FOUNDATION's funders are still giving 3 years after their first grant; 59% 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
FOUR MOUNDS FOUNDATION draws 72% of its grant income from funders outside Iowa, across 8 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $308k arriving through sponsors registered in 4 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.
