The Lewis 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 cold application is unlikely to be considered and should not be sent.
- Its filings show that 85% of grant dollars to organisations went to groups it had funded in earlier filings, so the realistic route in is an existing relationship or a warm introduction.
- Typical grants fall between $150,000 and $1,000,000, with a median of $500,000 and half of its grants at $500,000 or less, so any request should be sized with that pattern in mind, though the largest single grant was $4,000,000, so the typical band is not a ceiling.
- The filings show grants mainly in Colorado, District of Columbia, California and Illinois, but no geographic focus is stated, so an organisation elsewhere should not rule itself out on that basis.
- Its purposes vary widely across education, culture, environment, philanthropy and media, so fit depends more on the relationship than on a single field.
