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.

Source: IRS Form 990-PF Part XV and Form 990 Schedule I, tax years 2019–2025. These are grants already paid, a record of what an organization funds rather than an open call. 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.
