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

Key takeaways

  • The foundation makes contributions only to preselected organisations and does not accept unsolicited requests, so a small charity should not send it a cold application.
  • Its giving is heavily repeat: 95% of its grant dollars to organisations went to groups it had also funded in the earlier filings, so the list is largely made up of familiar names.
  • Half of its 119 grants to organisations were $300,000 or less, and about 8 in 10 fell between $35,000 and $2,000,000, so a modest request sits within the typical band, which is not a ceiling, since its largest grant was about $14,500,000.
  • Its recorded grants cover universities, medical colleges and hospitals, research bodies, and organisations working in youth education, mental health and support for people with disabilities, and its grants have mainly gone to Puerto Rico, Connecticut, New York, Massachusetts and California, but no geographic focus is stated, so that spread should not be read as a limit on who may apply.
