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

Key takeaways

  • The filing describes the foundation as by invitation only and says it does not accept unsolicited requests, so a cold application is unlikely to be considered; a warm introduction or an approach the foundation has already invited is the realistic route in.
  • Its stated focus is children's wellbeing, human and environmental health and connection to nature, through its Project One Health model, so work that connects children or adolescents with nature fits most clearly.
  • About 8 in 10 of its grants fall between $2,500 and $200,000 and the median is $10,000, so a modest request near $10,000 is a sensible size, though the largest grant was about $23,500,000, so that band is not a ceiling.
  • In its most recent filing, 95% of grant dollars to organisations went to organisations it had also funded in earlier filings, so a new applicant should expect the money to flow mainly to existing grantees and should build a relationship before asking.
  • The filings show grants mainly in the United States, North Carolina and Florida, but no geographic focus is stated, so treat that as a pattern rather than a rule about who may apply.
