Ideal Applicant
Established domestic or international nonprofits working in health, education, livelihoods, justice, or spiritual formation with evidence of measurable impact and the capacity to scale or partner.
Good Fit
- • Programs clearly aligned with the foundation's portfolios (health, education, livelihood, justice, spiritual formation).
- • Demonstrated results and scalable models or replicable impact.
- • Referral or introduction from a current partner or past grantee.
- • Organizational capacity to manage mid-size grants (tens to hundreds of thousands).
Geography
Observed giving in the latest year covers 39 U.S. states plus international locations, with only about 5% of grant dollars staying in the foundation's home state, indicating a national and international footprint.
Recipient Variety
The latest year shows 82 distinct recipients across multiple sectors and 63 new entrants, and three years of data confirm a broad and diverse recipient set rather than a tiny closed circle.
New Applicants
Behavioral evidence shows a high rate of new grantees (63 new recipients in the latest year, ~77%), which indicates the foundation regularly adds unfamiliar organizations; however, the website also states funding is by preselection and recent EOI windows were closed, so public application opportunities appear limited even though new entrants have been incorporated.
