Unsolicited applications are not accepted

This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.

Key takeaways

  • The foundation does not accept unsolicited requests and works by invitation only, so a cold application is unlikely to be considered; the practical route is to approach it only where an introduction or invitation is possible.
  • If that route exists, the work fits best where it overlaps with its stated themes of art exhibitions, arts research, community support and youth engagement, and its grantmaking record also includes churches and organisations involved in food assistance.
  • Half of its 30 grants to organisations were $25,000 or less, so a modest request is closer to its usual giving, although about 8 in 10 grants fall between $200 and $1,500,000, a typical band rather than a limit, as its largest grant was about $12,000,000.
  • In the latest filing, 22% of its grant dollars to organisations went to groups it had also funded in earlier filings, so it does return to existing grantees.
  • The filing states no geographic focus, and most recorded grants have gone to Massachusetts, New York, District of Columbia and Maryland, but that pattern is not a rule about who may apply.
