Ideal Applicant
A Hawaii-based 501(c)(3) nonprofit working in environmental stewardship, early childhood education, arts & culture, or youth development with an operational or capital need and established local programs.
Good Fit
- • Primary program delivery in Hawaii
- • 501(c)(3) nonprofit status
- • Work in environment, early childhood, arts, or opportunity/youth services
- • Clear case for operating support or capital/project funding
- • Willingness to apply by letter or online and to work with local program staff
Geography
Observed giving is highly localized: the latest year shows about 94% of dollars directed to Hawai‘i despite grants to three states overall, so the footprint is essentially state-focused.
Recipient Variety
The latest year funded 84 distinct recipients across many program types (environment, education, arts, youth), with modest financial concentration (top one ~10%, top five ~27%), indicating a broad and diverse recipient set for the foundation’s size.
New Applicants
Direct evidence of openness includes a public website with application instructions, a rolling online or letter application route, and a high number of new grantees in the latest year (56 new recipients); the foundation also lists a named contact and phone number, though it requires 501(c)(3) status and Hawaii-focused work.
