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 2020 to 2021, from $3.4M to $5.3M (+58%).
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: 2017 70% · 2018 34% · 2019 61% · 2020 48% · 2021 27% · 2022 37% · 2023 37% · 2024 33% · 2025 59%. Grants only. Government contracts and fees sit inside program revenue.
94% of PREVENTION WORKS INC’s revenue is contributions — more reliant on donations than three-quarters of its peers (51% for the typical peer).
Surplus & reserves

From the IRS filings of PREVENTION WORKS 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
PREVENTION WORKS INC leans on a few funders — its largest provides 82% of grant income and the top three 90%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left

“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
53% of PREVENTION WORKS INC's funders are still giving 3 years after their first grant; 71% 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
100% of PREVENTION WORKS INC's grant income comes from Michigan funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $418k arriving through sponsors registered in 1 state 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.
