    Network Intelligence

    Funding follows networks, not keywords

    SciRise maps 4.8M+ grants across 16,000+ foundations to identify which ones are most likely to fund organizations like yours — based on who they already fund, not just what they say they fund.

    Data sourced from IRS 990 and 990-PF filings and publicly available foundation websites. Grant data, financial figures, and organizational details reflect historical filings and may not represent current operations or funding priorities. Verify directly with the foundation before applying. See an issue? Let us know.
