Questions about foundations in Hawaii
What are the largest foundations in Hawaii?
By grants reported on their latest 990s, the largest are Trustees of the Estate of Bernice Pauahi Bishop DBA Kamehameha Schools ($33.4M across 109 grants), Aloha United Way Inc ($14.0M) and Kanu O Ka Aina Learning Ohana ($6.9M). Together the top 10 account for 47% of the $200.7M given by the 290 grantmakers in Hawaii that made at least 5 grants. Organizations that reported large giving in fewer grants, usually a single transfer to an affiliated charity, are left out of the ranking.
How big is a typical foundation grant in Hawaii?
The typical grant is about $19K (the median of each grantmaker's average grant). Half of these grantmakers gave less than $58K in total in their latest filing year, so many are small foundations that give to a few organizations they already know. The largest funders make many more grants, but also get the most requests.
How do I find Hawaii foundations that accept unsolicited proposals?
Most private foundations don't run an open application. Their 990-PF says whether they only give to preselected charities, and their past grants show who they actually fund. Start with the funders above whose grant counts and typical grant size fit your budget, then check each profile's grant history for organizations like yours before you reach out. Read the grant prospecting guide.
