$96,075 spent26% of program spending
The 2 programs described on its FY2024 Form 990, listed largest first by expense. Program spending in total: $375,794.
The organization over time
Each line starts at 100 in 2021, so what you read is the shape rather than the size: 150 means half as much again as 2021, 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 $231k to $497k (+115%).
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: 2022 25% · 2024 16% · 2025 76%. Grants only. Government contracts and fees sit inside program revenue.
101% of CORNERSTONE’s revenue is contributions — more reliant on donations than three-quarters of its peers (83% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 0 of the last 5 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.
Who funds it, year by year
2017 → 2023: the base broadened from 6 funders to 16 funders, grant income rose $44k → $113k.
2 of 34 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 9% 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 CORNERSTONE’s funders (the co-funder graph). Top 30 of 34 funders by total. 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
CORNERSTONE has a broad base — no single funder exceeds 19% of grant income, and it takes 4 funders to reach half.
the vertical line marks half of all grant income — 4 funders to its left
Largest funder’s share by year: 2017 45% · 2018 32% · 2019 40% · 2020 50% · 2021 70% · 2022 32% · 2023 23% — 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
41% of CORNERSTONE's funders are still giving 3 years after their first grant; 53% 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
85% of CORNERSTONE's grant income comes from Minnesota funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $120k arriving through sponsors registered in 2 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.
Against its field
CORNERSTONE runs a healthier operating margin than half of the 3,482 youth development nonprofits its size.
