Isenberg Family Charitable Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- The foundation accepts requests by invitation only and states that it does not accept unsolicited requests, so a cold proposal is unlikely to be considered; a relationship or introduction is the realistic route.
- Its filing shows grants chiefly for general operational support, plus one field-building grant, and its stated themes centre on marginalised and vulnerable communities, with a priority geography given as globally, the Global South and persistent poverty regions in more developed economies.
- Typical grants fall between $10,000 and $250,000, with a median of $69,500, so a modest request sits well within its usual giving, though that band is not a ceiling.
- Most of its grant dollars go to organisations it had already funded in an earlier filing (83%), which points to a relationship-led funder.
- An organisation with no existing link to the foundation should not expect an unsolicited request to succeed.
