How to use this list
A foundation is listed because its own latest tax return itemizes grants to organizations in Iowa that we classify as stem, by the purpose the foundation wrote or by the recipient's IRS activity code. Their typical grant is the middle of the funders' own typical grants across everything they fund. Start with funders whose typical grant is close to what you need and whose past recipients look like your organization, then open the profile for all of its grants and any application instructions.
Of these 43 foundations, 22 describe how to apply on their latest return; many others give only to organizations they already know. A badge such as Gave $1.2M in 2024 repeats what the latest return reports; it does not mean the foundation is accepting proposals now.
Facts on this page come from the foundation's own IRS Form 990-PF filings as published by the IRS. Grantvello does not know whether a foundation is accepting proposals right now: a past grant is not an open opportunity. Always confirm current guidelines with the funder before applying.
