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

Key takeaways

  • The foundation states that it works by invitation only and does not accept unsolicited requests, so an organisation without an introduction or invitation should not send a cold application.
  • Its grants are recorded as general support across health, housing, youth, education, arts, community and refugee work, so whether your work fits is best judged against those broad areas.
  • A typical grant falls between $5,000 and $100,000, about 8 in 10 of its 122 grants fall in that band, half are $25,000 or less, and the median is $25,000, so a request near that level is in line with its giving; the largest grant was $500,000, so the band is not a ceiling.
  • Repeat recipients received 86% of its grant dollars to organisations, which makes it relationship-led, and the filing states no geographic focus, so the states where most of its grants go are a pattern rather than a rule about who may apply.
