Three Guineas Fund
Its FY2025 filing reports that it funds preselected organizations and did not take unsolicited requests; check the foundation's own site before ruling it out.
Read this first · the figures below need context
100% of Three Guineas Fund’s FY2022 grant dollars went to Tides Foundation, not to grantees.
Its money now reaches organizations through that sponsor, which does not report who recommended each grant. FY2022 names 0 organizations directly, so a portfolio cannot be read from it. Everything below is therefore FY2020, the last year Three Guineas Fund named its own grantees at scale: 6 organizations, $110k. It is dated, not current.
Organizations named directly on the return
Amber years are those where most dollars went to a sponsor.

Dollar for dollar, its grants (FY17–22) land where the poverty rate runs at 11%, against an area that typically sits at 9%. 100% of its dollars go to grantees based in above-average-need neighborhoods. Most of its grants land in higher-need ZIPs.

Counted here: distinct organizations funded across 2017 to 2025, not grant rows in a single year, so this will not match the grant count on the cover.

How do I get to Three Guineas Fund?
Find your warmest path to Three Guineas Fund through trustees and officers whose names appear on both boards. Search for your organization and Plinth traces the shortest route it can evidence.
Each link is a name appearing on two organizations’ public IRS 990 filings, matched on that name and, where the filings support it, on location. A same-state match has geographic support, which is a second matching feature rather than confirmation that the two are one person; a cross-state one is the likeliest to be two people who share a name. Every hop shows its tier, low-confidence and distant paths are held back rather than guessed, and it is worth confirming the person before you use the introduction.
