Funding search

Find who already funds work like yours.

Private foundations don’t post open calls, so nobody can search them. We read IRS filings instead — 9.6 million grants from 174,053 foundations and grantmaking charities, searchable by what the money was actually for.

Private foundations rarely accept unsolicited applications and the route in is usually a program officer; grantmaking charities and associations more often run real application cycles, so check their website.
