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 small charity should not send a cold proposal and should first find a route to an invitation.
  • Its grants have centred on climate action and regenerative agriculture, with conservation, youth health, food and tribal work also appearing, so projects in those areas are the closest fit.
  • About 8 in 10 of its grants fall between $75,000 and $500,000, with a median of $200,000, so a request in that range is typical, though its largest grant was $1,000,000 and the band is not a ceiling.
  • Repeat giving is a large part of its grant-making, with 67% of grant dollars going to organisations it had also funded in earlier filings, so existing relationships appear to matter.
  • The filings state no geographic focus, and the grants mainly in California, Colorado and Virginia describe past giving only, not who may apply.
