Unsolicited applications are not accepted

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

Key takeaways

  • The filings state that the foundation does not accept unsolicited requests, so a cold application is unlikely to be considered, and the realistic route in is an existing connection.
  • Its stated themes are conservation, education and public well-being, and it stresses partnership and attention to underserved voices, so a request should show how the work fits those areas.
  • Most grants are modest: half of its grants to organisations were $5,000 or less and the median was $5,000, so a request near that size fits best.
  • About 8 in 10 grants fall between $2,500 and $650,000, which is a typical band rather than a ceiling, since the largest grant was $4,500,000.
  • Repeat giving is strong, with 83% of its grant dollars to organisations going to groups it had also funded in the two earlier filings, so it appears relationship-led; no geographic focus is stated, and although its grants have mainly gone to Maine, New Hampshire, the District of Columbia, Massachusetts and South Dakota, that is a pattern in the grants, not a rule about who may apply.
