Anna-Maria and Stephen Kellen Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- The foundation does not accept unsolicited requests, so a small charity should not send a cold application; it should look for an introduction or wait to be invited.
- Its stated themes are medical research, cultural institutions, education, and human and social services, so a request should show how the work fits one of these.
- Half of its 501 grants to organisations were $75,000 or less, so a modest request is closer to its usual giving, and most grants fall between $10,000 and $560,000, though the largest was about $11,000,000.
- Its annual giving fell from $76,293,784 to $25,103,179 over the years shown, and 89% of its grant dollars in the latest filing went to organisations it had also funded in an earlier filing, so approaching it is relationship-led.
- Its filings show grants mainly in New York, Minnesota and Massachusetts, but no geographic focus is stated, so location alone should not decide whether to approach it.
