Key takeaways

  • The foundation's filed grants cover a wide mix of work, including environmental, housing, food, population and humanitarian causes, so check that your own work fits before you write.
  • No geographic focus is stated, but most of its grants have gone to organisations in Washington, Colorado, Massachusetts, District of Columbia and Pennsylvania, so a group elsewhere should ask for an application to test the fit.
  • About 8 in 10 of its grants to organisations fall between $4,500 and $18,000, with a median of $10,500, so a request near that size is typical, although its largest grant was $30,000.
  • In its latest filing, 74% of grant dollars to organisations went to groups it had funded before, so a first approach should be made early and treated as a relationship to build.
  • To apply, email the foundation for an application and submit it by the July 1 deadline.
