The Roberto Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- The Roberto Foundation, based in Irvine, California, accepts no unsolicited requests and gives only to charitable organisations it has preselected, so a small nonprofit should not send it a cold application and should wait to be invited.
- Its filing shows grants mainly in California, but no geographic focus is stated, and it has given to health, education, youth services, land trusts, food assistance, arts and religious institutions with no subject priority.
- About 8 in 10 of its 15 grants to organisations fall between $150,000 and $1,300,000, with a median of $200,000 and a largest grant of $2,000,000, so that band is typical rather than a ceiling and any request should be sized with the median in mind.
- Every grant dollar it gave to organisations in its latest filing went to groups it had also funded in earlier filings, so its giving is strongly repeat and relationship-led.
- The filing gives no timing, and the foundation's invitation process is not described, so any approach should rest on an existing connection rather than an assumption about when it might accept requests.
