Questions about foundations in Wisconsin
What are the largest foundations in Wisconsin?
By grants reported on their latest 990s, the largest are University of Wisconsin Foundation ($548.8M across 5 grants), Thrivent Charitable Impact & Investing ($84.6M) and Children's Hospital of Wisconsin Inc ($75.7M). Together the top 10 account for 44% of the $2.6B given by the 1,471 grantmakers in Wisconsin 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 Wisconsin?
The typical grant is about $21K (the median of each grantmaker's average grant). Half of these grantmakers gave less than $80K 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.
Are there community foundations in Wisconsin?
Yes. We found 31 community foundations in Wisconsin with grant activity. The largest by giving are Thrivent Charitable Impact & Investing, Greater Milwaukee Foundation Inc and St Croix Valley Foundation. Community foundations pool gifts from many local donors and usually run open grant rounds for nonprofits in their area, which makes them a good first stop for local funding.
How do I find Wisconsin 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.
