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.

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.

02Who funds it

Who funds it, year by year

2017 → 2023: the base broadened from 26 funders to 97 funders, grant income rose $2.4M → $8.0M.

50 of 177 of your funders are donor-advised or pass-through sponsors (tagged DAF)38% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

Left out of every figure on this page: $10k from one payer (the payer shares this organization's board, largest The Harold Grinspoon Charitable Foundation). These are real filings, and they are not money THE HAROLD GRINSPOON FOUNDATION raised.

From the IRS filings of THE HAROLD GRINSPOON FOUNDATION’s funders (the co-funder graph). Top 30 of 177 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

THE HAROLD GRINSPOON FOUNDATION has a broad base — no single funder exceeds 9% of grant income, and it takes 10 funders to reach half.

the vertical line marks half of all grant income — 10 funders to its left

44% 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 THE HAROLD GRINSPOON FOUNDATION.

55% of THE HAROLD GRINSPOON FOUNDATION's funders are still giving 3 years after their first grant; 59% 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.

Funder states come from each funder’s own filing. $20M arriving through sponsors registered in 25 statesis 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.

03Its place in the field

Funders to approach

Grantmakers that don’t fund you yet, surfaced two ways: they back organizations that share your funders, or their grantees resemble your mission. The ones both signals agree on come first. Your 177 funders put you under-funded among the 400 organizations that share them.

From the co-funder graph (funders backing at least two comparable organizations, shrunk for grantee count, donor-advised and mega-funds excluded) and the universe embeddings. A research starting point; overlap is association, not a guarantee of fit.
