Data sources

Everything comes from public government records. We don’t buy or copy other grant databases.

  • Foundation gifts: IRS Form 990-PF returns, 2025 e-filed returns
  • Nonprofit names, states and revenue: the IRS list of tax-exempt organizations
  • Federal grant deadlines, where shown: Grants.gov

Not every foundation files electronically, so some are missing.
