Key takeaways

  • The Duffy Foundation funds a broad mix of causes with no stated programme area, including social-service and domestic-violence organisations, food assistance providers, health services, housing organisations, schools and literacy groups, arts and cultural bodies, animal welfare organisations, and land and watershed conservation groups, so fit is judged case by case rather than against a defined mission; nearly all its grant dollars go to organisations in Michigan, though the foundation states no formal geographic focus.
  • It makes contributions only to preselected organisations and does not accept unsolicited requests, and in its latest filing all of its grant dollars to organisations went to groups it had also funded in the two filings before that, so this is a highly relationship-led funder rather than one that runs an open competition.
  • Most grants fall between $25,000 and $250,000, with a median of $80,000, so that is a realistic size of request if you are known to the foundation or approached by it.
  • Because the process is invitation only and giving is heavily concentrated on existing relationships, small nonprofits without a prior connection should not expect a direct, unsolicited application to succeed.

Overview

Duffy Foundation is a US private foundation based in Ann Arbor, MI.

What they fund

Profile based on the foundation's IRS Form 990-PF filings (TY2024, TY2023, TY2022) only: no website or other web source for the foundation was found. Every statement is checked against the filings. Sources read on 7 October 2026.

Priority Areas

The Duffy Foundation's filings do not state a programme area; its recorded grants instead support a broad mix of charitable organisations. Recipients include social-service and domestic-violence organisations, food assistance providers, health services, housing organisations, schools and literacy groups, arts and cultural bodies, animal welfare organisations, and land and watershed conservation groups. The stated purposes are generic—use consistent with 501(c)(3) status—so the record does not identify a narrower purpose for these awards. Nearly all grant dollars went to Michigan organisations.

Geographic Focus

No geographic focus is stated; the filings show grants mainly in Michigan.

How to apply

The foundation makes contributions to preselected charitable organisations and does not accept unsolicited requests; the filing gives no application steps.
