The organization over time
Each line starts at 100 in 2024, so what you read is the shape rather than the size: 150 means half as much again as 2024, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $75k to $2.3M (+3015%).
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.
45% of GREY BULL RESCUE FOUNDATION’s revenue is contributions — about as donation-reliant as the typical peer (69% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 1 of the last 2 reported years ran a deficit.

Who funds it, year by year
Grant support over time, funder by funder — shade shows the grant size each year.
5 of 13 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 39% 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 GREY BULL RESCUE FOUNDATION’s funders (the co-funder graph). Top 12 of 13 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
GREY BULL RESCUE FOUNDATION has a broad base — no single funder exceeds 18% 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
78% 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 GREY BULL RESCUE FOUNDATION.
“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.
Where its funders are
GREY BULL RESCUE FOUNDATION draws 65% of its grant income from funders outside Florida, across 4 states in all.
Funder states come from each funder’s own filing. $107k arriving through sponsors registered in 3 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.
