Martin R Prince Charitable Foundation Inc
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
58% of Martin R Prince Charitable Foundation Inc’s FY2025 grant dollars went to President And Fellows Of Harvard College, not to grantees.
Its money now reaches organizations through that sponsor, which does not report who recommended each grant. FY2025 names 22 organizations directly, so a portfolio cannot be read from it. Everything below is therefore FY2024, the last year Martin R Prince Charitable Foundation Inc named its own grantees at scale: 15 organizations, $1M. It is dated, not current.
Organizations named directly on the return

Does the money reach high-need areas?
Each grant placed by the hardship in its grantee’s ZIP, against the area’s typical level.
Its human-services grants (FY18–18, $200) land where the poverty rate runs at 7%, against an area that typically sits at 8%. 0% of those dollars go to grantees based in above-average-need neighborhoods. Its grants skew toward lower-need ZIPs.

Who it funds again
Organizations funded in more than one year, against those funded once.
Grantees it renews have grown median revenue +51% since the first grant, against +44% for those funded once.
50 repeat relationships: 19 still active in FY2024, 31 since wound down; 2 grantees were first funded in FY2024 (too recent to call). Read against FY2024, the last year this funder named its own grantees directly; its giving has since run through a sponsor, which reports no donor behind each grant.

How this is measured
54 grantees tracked through their own filings, 2017–2025.
Each grant beside the grantee’s revenue from every source, year by year.
How this is measured
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. 54 of the 76 grantees resolved in that span have returns of their own we could reconcile.
Each grantee is resolved to its own IRS returns. Association, dated; never a causal claim.

Warm introductions · Powered by PlinthPlus
How do I get to Martin R Prince Charitable Foundation Inc?
Find your warmest path to Martin R Prince Charitable Foundation Inc 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.
