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.
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.
100% of SOLE BROTHERS’s revenue is contributions — more reliant on donations than three-quarters of its peers (100% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 5 of the last 9 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 1 funder to 3 funders, grant income rose $5k → $7k.
1 of 4 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 0% 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 SOLE BROTHERS’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
SOLE BROTHERS leans on a few funders — its largest provides 77% of grant income and the top three 100%; half comes from just 1 funder.

“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.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $203 arriving through sponsors registered in 1 stateis 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.
