Ideal Applicant
Mid‑to‑large nonprofit with a strong California presence or visibility in Los Angeles—particularly universities, museums, education, arts, or human‑rights organizations that match large, discretionary general support grants.
Good Fit
- • Located in California or has a significant program presence in Los Angeles.
- • Mission aligned with education, arts & culture, or human‑rights work.
- • Organizational scale and credibility to receive six‑figure general support.
- • Existing relationships or introductions to foundation leadership or intermediaries.
- • Track record of prior partnerships with major universities or cultural institutions.
Geography
Giving is heavily concentrated in California — roughly 88% of dollars stayed in‑state in the latest year, with most large grants to Los Angeles institutions despite grants appearing in a handful of other states.
Recipient Variety
The latest year shows a broad set of recipients (29 distinct organizations and 46 grants) across education, arts, and human‑rights purposes; while the top five recipients captured a majority of dollars, many independent organizations were funded.
New Applicants
Observed behavior shows new recipients are added (15 new grantees in 2023), so new entrants can appear in the portfolio, but the foundation’s stated 'preselected only' policy and absence of a public application route mean an unfamiliar organization is unlikely to access funds without relationship‑level introduction.
