Who funds disability services in South Dakota
Private foundations that have already paid grants to disability services in South Dakota, taken from what they reported to the IRS. These are not open calls. This is money that already moved.
One of them, as proof
Every number above comes from filings you can check yourself. Here is one funder from this group with its full record open: every grant it reported, who received it, and for what.
The other 9 are in the report.
Only 10 foundations here
That is too thin to charge for, so there is no paid report for disability services in South Dakota. Two things usually work better. Plenty of these funders give across state lines, so check a neighbouring state. Or try a broader cause that still covers what you do.
Where this comes from
Every private foundation in the United States files a Form 990-PF listing each grant it paid: recipient, address, purpose, amount. The IRS publishes all of it as raw XML almost nobody reads. We read it and keep the history.
