Westridge Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- Westridge Foundation does not accept unsolicited requests, so a charity that has not been invited should not send it a proposal cold.
- Its grants span many fields, so fit depends less on subject than on whether the foundation has already chosen to fund organisations like yours.
- About 8 in 10 of its 114 grants to organisations fall between $5,000 and $200,000, and half were $25,000 or less, so a modest request is the realistic size, although its largest grant was $2,250,000.
- Most of its grant dollars (90%) went to organisations it had also funded in an earlier filing, so this is a relationship-led foundation, and an approach is unlikely to succeed without that prior connection.
Overview
Westridge Foundation is a US private foundation based in Wilmington, DE.
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 recorded grants span several kinds of charitable work rather than a stated single field. Recipients include universities and medical research institutions, colleges and schools, museums, artist-development bodies and film organisations. Supported purposes range from clinical trials and research programmes to scholarships, arts and film projects, online education, and unrestricted support. The records also show grants to community-service and healthcare organisations, food-support providers, animal-welfare organisations, and groups concerned with reproductive health and civic participation. Some awards are assigned to a specific fund or project, while many are recorded as general or unrestricted support. The filings describe this pattern of giving but do not state a general eligibility framework or an open application route.
Geographic Focus
No geographic focus is stated; the filings show grants mainly in California and New York.
