The IV (four) Fund
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- The foundation works by invitation only and says it does not accept unsolicited requests, so a cold proposal is unlikely to be considered; wait to be invited before applying.
- Its stated focus is mental well-being, alongside the arts, education, connection to nature, and community and belonging, and it funds upstream work that builds resilience before crisis.
- Projects that are internationally based or focused are not funded, so international work should not apply.
- Its typical grants run from $2,700 to $75,000, with a median of $18,000, which is a realistic size for a request, though the largest grant was about $1,400,000 and the band is not a ceiling.
- In the filing, 89% of grant dollars to organisations went to groups it had funded in earlier years, so relationships appear to matter, although the filing does not show that new organisations are excluded.
