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

Key takeaways

  • The Aldarra Foundation does not accept unsolicited requests, and its filing says it works by invitation only, so a cold proposal is not the way in.
  • Its typical grants to organisations run from about $150,000 to $14,000,000, with a median of about $920,000 and a largest grant of $51,000,000, so a request of a few hundred thousand dollars would sit within its usual range.
  • No geographic focus is stated, and its filing shows support for a wide mix of organisations, including a children's hospital, cancer research, public media and a school for deaf and hard-of-hearing children, so the fit should be judged on purpose rather than location.
  • Nearly all of its grant dollars went to organisations it had funded in earlier filings, so a new applicant should first look for an existing connection to the foundation, though this does not rule out a new organisation.
