Charles Lee Powell Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- The foundation states that it does not accept unsolicited requests and works by invitation only, so a small nonprofit should not send it a cold proposal.
- Its stated focus is science and engineering support at four California universities, with California as its priority, so work outside that field or area is unlikely to fit.
- Typical grants fall between $650,000 and $825,000, and half of its 13 grants to organisations were $650,000 or less, so a modest request would sit well below its usual pattern.
- In its most recent filing, all of its grant dollars to organisations went to groups it had also funded in earlier filings, and it paid $2,775,000 in the year.
