Ideal Applicant
A Washington-state or Cascadia-region nonprofit doing community-focused work (BIPOC-centered social impact, climate/environmental justice, or civic impact) with an established local presence and readiness for multi-year, general operating support.
Good Fit
- • Based in Washington state or active in the Cascadia region.
- • Work centers BIPOC-led social impact, community partnership, or environmental justice.
- • Seeks general operating or multi-year trust-based support.
- • Has local credibility or relationships with regional intermediaries or prominent grantees.
- • Can document measurable community impact and partnership orientation.
Geography
Giving is heavily concentrated in the foundation's home state, with about 94% of dollars going to Washington; a handful of small out-of-state grants appear but the footprint is essentially local/regional.
Recipient Variety
The latest year shows a broad portfolio—155 grants to 118 distinct recipients—including many independent nonprofits; while top recipients receive sizable shares, the foundation still funds a large and varied set of organizations.
New Applicants
Direct evidence shows 40 new recipients in the latest year (about one-third of grantees), indicating some turnover, but the foundation publicly says it does not accept unsolicited proposals and funds primarily preselected recipients, so new entrants typically need referral or engagement rather than an open application.
