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.

12 funders, 61 recipients, grants matching “observation” only. Ribbon width is proportional to the total given; each funder has its own colour (smaller funders in gray). Hover a name to isolate its flows, click a funder to open it. Drag to move around; zoom with the buttons, a double-click, or the wheel after clicking the map.

This is one keyword. PaperOrbit reads your actual paper and searches on everything in it — population, methods, outcomes — then explains why each funder fits.

Local foundations often favor nearby communities. Enter a ZIP code to see foundations based near you, and where grant money has actually landed in your area.

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.
