Ideal Applicant

A California-based nonprofit with a track record in medical research, homelessness/food security, or clinic and community services, able to manage mid-to-large grants and engage through local networks or invitations.

Good Fit

  • Organization is based or operates in California.
  • Work aligns with medical research, homeless services, food banks, clinics, or related human services.
  • Capacity to absorb and report on mid-size to large grants ($50k–$600k).
  • Existing relationships or credible introductions to foundation leadership or past grantees.
  • Track record or reputation within the local Bay Area nonprofit ecosystem.

Geography

Restrictive

Grantmaking is heavily concentrated in California (about 93% of dollars in 2024) with only one other state receiving a small share; the footprint is essentially in-state.

Recipient Variety

Broad

The latest year shows wide variety: 61 grants to 37 distinct recipients across health, homelessness, food security, education and other services, and many different organizations were funded rather than a tiny repeat set.

New Applicants

Restrictive

Although 36 new recipients appeared in 2024, the foundation explicitly marks grants as preselected and there is no public application route or visible contact path, so new entrants are likely funded by invitation rather than open solicitation.
