Tansy Charitable Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- The foundation states that it does not accept unsolicited requests and gives only to organisations it preselects, so a small nonprofit should not send it a cold proposal; the only realistic route in is an invitation.
- About 8 in 10 of its grants to organisations fall between $600,000 and $17,000,000, with a median of $3,500,000 and a largest grant of $25,000,000 to GiveWell, so that band is typical rather than a ceiling, and any invited request should be sized with that scale in mind.
- Repeat giving is heavy: 97% of its grant dollars to organisations went to recipients it had also funded in an earlier filing, which suggests that an existing relationship matters far more than a fresh approach.
- No subject area or geographic eligibility rule is stated, and the filings show grants mainly in California, Massachusetts and Georgia, which describes past giving rather than a limit on who may apply.
- The filings do not set out an application window, so there is no deadline to plan around.
Overview
Tansy Charitable Foundation is a US private foundation based in New York, NY.
What they fund
Profile derived from the foundation's IRS Form 990-PF filings (TY2025, TY2024, TY2023) and web pages about the foundation (insidephilanthropy.com), with every statement checked against those sources. Sources read on 12 October 2026.
Priority Areas
The filing labels every reported grant as general use. The recipient rows show repeated support for a small group of organisations, including international health and development organisations, philanthropic and grantmaking institutions, and a university, alongside other charitable recipients. The same organisations recur across filings, and most recorded grant dollars went to a few recipients. An external account characterises the approach as large, unrestricted awards to a handful of trusted partners. The materials do not state a subject area that defines the foundation’s grantmaking or a geographic eligibility rule; the filing says it gives only to preselected charitable organisations.
Geographic Focus
No geographic focus is stated; the filings show grants mainly in California, Massachusetts and Georgia.
