WHH Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- The filing says the foundation makes grants only to organisations it has preselected and does not accept unsolicited requests, so a small nonprofit that has not been invited to apply should not send a cold request.
- Where an organisation already has a connection with the foundation, a conversation may be worth having, since 84% of its grant dollars to organisations in its latest filing went to organisations it had also funded in an earlier filing.
- About 8 in 10 of its 367 grants to organisations fall between $5,000 and $80,000, with a median of $12,500, so a modest request sits within its typical range, though that band is not a ceiling because its largest grant was about $2,250,000.
- The filing gives no further application steps or timing, so any approach should be measured and relationship-led rather than built around a deadline.
Overview
WHH Foundation is a US private foundation based in San Marino, CA.
What they fund
Profile based on the foundation's IRS Form 990-PF filings (TY2024, TY2023, TY2022) only: no website or other web source for the foundation was found. Every statement is checked against the filings. Sources read on 7 October 2026.
Priority Areas
The foundation's grants go to a varied group of charitable organisations. Repeated recipients include hospitals and medical institutions; universities and schools; libraries, museums and arts organisations; and social-service and community organisations working with families, young people, people experiencing homelessness and food access. Other grants go to organisations in nonprofit support, science, public policy and education. The filing describes grants mainly as programme or project support and general support, without naming narrower grant fields. Its recorded giving therefore spans institutional and community-based organisations rather than concentrating on a single kind of recipient.
Geographic Focus
No geographic focus is stated; the filings show grants mainly in California and Oregon.
How to apply
The filing indicates that grants are made only to preselected charitable organisations and that unsolicited requests are not accepted; it gives no further application steps.
