Nonprofit Lookup
Search the IRS 501(c)(3) database for any non-profit. Returns EIN, location, NTEE category, and direct links to recent Form 990 filings via ProPublica's open mirror.
Why this exists
When a non-profit shows up in your inbox — board outreach, vendor relationship, sponsorship request, partner foundation — the first question is always the same: who actually are they? Public 990 filings tell you total revenue, exec compensation, governance, and program scope. ProPublica mirrors that data and exposes a clean API.
Useful for PE folks evaluating deal-related foundations, MSP owners reviewing CIO advisory boards, and anyone whose calendar includes "non-profit board meeting" without context.
