Wisconsin Family Office List

This Wisconsin list brings together a small group of family offices with a range of investment interests. Milwaukee accounts for four of the eight listed firms, while Brookfield, Appleton, Madison and Jackson each account for one. The database includes four single-family offices and four multi-family offices, so visitors can compare different organizational structures when researching potential investors or market participants. Disclosed focus areas include alternative investments and hedge funds, with additional interests spanning private equity and real assets, venture capital, real estate, angel investing, multi-family and self-storage. Three offices have disclosed assets under management. The listed firms were founded between 1968 and 2013, with one founded after 2010. Use the table to identify relevant profiles, then assess fit based on your own mandate, geography and investment stage. The page is a research starting point, not an indication that any firm is actively investing or accepting proposals.

Questions about this list

What kinds of investors are represented in the Wisconsin list?

The page includes four single-family offices and four multi-family offices. Their recorded interests include alternative investments, hedge funds, private equity and real assets, venture capital, real estate, angel investing, multi-family and self-storage. A focus label can help you screen profiles, but it does not confirm a current mandate or appetite.

Where are the listed offices located?

Milwaukee is the most represented city, with four firms. Brookfield, Appleton, Madison and Jackson each have one. The page also includes seven nearby offices to give users a wider regional set of profiles than the Wisconsin-located entries alone.

How should I approach a Wisconsin family office?

Start by checking whether the firm's recorded focus aligns with your sector and type of opportunity. Prepare a concise explanation of the business, capital need, stage and proposed use of funds, then use an appropriate verified decision maker and follow the firm's stated process where available. The list does not indicate that a firm is soliciting proposals.

How complete is the public AUM information?

Assets under management are disclosed for three of the eight listed firms. For the other profiles, AUM is not available as a disclosed field on this page. Treat the available figures as partial coverage and avoid comparing firms solely on that basis.

What does the full Wisconsin list add?

The full list provides contact data, decision makers and check size fields to support more focused research and outreach planning. Those details are available by request through the form. A request provides data for your own evaluation and does not promise an introduction, investment or outcome.
