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.

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.

From the IRS filings of NATIONAL DOWN SYNDROME SOCIETY’s funders (the co-funder graph). Top 30 of 139 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.

NATIONAL DOWN SYNDROME SOCIETY has a broad base — no single funder exceeds 27% of grant income, and it takes 4 funders to reach half.

the vertical line marks half of all grant income — 4 funders to its left

80% 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 NATIONAL DOWN SYNDROME SOCIETY.

first grant+1y+2y+3y+4y+5y+6y

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

69% of NATIONAL DOWN SYNDROME SOCIETY'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.

Funder states come from each funder’s own filing. $4.2M arriving through sponsors registered in 13 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.

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 139 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.
