Each line starts at 100 in 2020, so what you read is the shape rather than the size: 150 means half as much again as 2020, 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.

03Who funds it

Who funds it, year by year

2022 → 2023: the base broadened from 4 funders to 6 funders, grant income rose $6k → $36k.

6 of 18 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 58% 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 GRINDSTONE MINISTRIES 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

GRINDSTONE MINISTRIES INC has a broad base — no single funder exceeds 27% 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

58% 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 GRINDSTONE MINISTRIES INC.

Largest funder’s share by year: 2022 56% · 2023 56% — broadly stable.

“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

58% of GRINDSTONE MINISTRIES INC's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $81k that is directly attributable, 100% of it comes from funders outside Oklahoma, across 8 states.

Funder states come from each funder’s own filing. $114k arriving through sponsors registered in 6 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.
