Kosasa Foundation
At a glance
Key takeaways
- The Kosasa Foundation funds work in Hawaiʻi, so a fit depends on your organisation operating there, within its themes of environmental stewardship, opportunity youth, arts and culture, and early childhood education.
- Keep requests modest and realistic: about 8 in 10 of its 214 grants to organisations fall between $15,000 and $175,000, with a median grant of $50,000, although the largest grant reached $1,000,000.
- Applicants must be 501(c)3 organisations, funds cannot be used to re-grant, and an organisation may only have one project supported per year; the process starts with a short questionnaire to check eligibility before access is given to an application portal, and the method otherwise varies by programme.
- A majority of its grant dollars, 62%, went to organisations it had already funded in its two previous filings, so relationships and a track record with the foundation appear to count for a good deal, and first-time applicants should apply with that in mind.
