Konzen Family Foundation
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 states that it does not accept unsolicited requests, so a small charity should not send it a cold proposal; the only route in is through an existing connection who can put you forward.
- Its grants to organisations are mostly modest: the median is $50,000 and about 8 in 10 fall between $20,000 and $180,000, so any request is best sized within that typical band, not against the largest grant of $650,000.
- Most of its grant dollars go to organisations it has funded before, with 82% of its grant dollars to organisations also funded in an earlier filing, so relationships appear to matter more than fresh applications.
- The filings show grants mainly in Washington, California and District of Columbia, but no geographic focus is stated, so do not read that pattern as a rule about who may apply.
