Common questions
Which foundations give to nonprofits in Weiser, Idaho?
Blue Cross of Idaho Foundation for Health Inc, Rk Mellon Family Foundation, Larry and Marianne Williams Family Foundation, Seneca Foods Foundation, Generations for Good Inc and 1 others reported grants to Weiser organizations on their latest Form 990-PF.
How do I approach a foundation that doesn't accept applications?
A foundation that checks "contributes only to preselected organizations" on its 990-PF won't review a cold proposal. Look at who it funds, find a shared board member, grantee or advisor, and ask for an introduction. Foundations that accept applications usually list a contact and deadlines in Part XV; we show that text on each foundation's page.
Is this list complete?
