GrantSonar — Funder Lookup & Grant Capture

Look up any U.S. funder's real giving history from 3.9M IRS records, and check your fit for any grant page you're reading.

Two tools for grant seekers — free, no account needed. FUNDER LOOKUP Select a funder's name on any page — a news story, a 990, a colleague's spreadsheet — right-click, and get its real giving history: total assets, grants paid per year, and top focus areas, sourced from 3.9 million itemized IRS Form 990 grant records across 233,000+ U.S. foundations. You can also search directly from the toolbar popup. Every result links to the funder's full free profile: payout rate, average and median grant size, leadership and board, and every grantee they have actually funded. GRANT CAPTURE Reading a grant opportunity on grants.gov, a state portal, or a funder's website? One click sends that page to GrantSonar's fit check, which scores it against your organization's profile — mission, programs, geography, applicant-type eligibility, and budget size — using the same engine that screens the full live grant database. PRIVACY BY DESIGN • No account required for funder lookup. • Zero data collection: no analytics, no tracking, no browsing history. • The extension reads the tab you're on only when you click capture — nothing is sent until you do. GrantSonar is a live U.S. grant database and AI grant workspace: find grants, check fit, draft, and review. The extension is free; a free GrantSonar account adds grant matching for your organization.
