About
We invest in exceptional founders across the Upper Midwest, including our home state of Wisconsin, where resilient industries and strong communities fuel innovation, growth, and value creation.
Investment approach
- Thesis
- The Winnow Fund’s strategy involves making numerous small investments in early-stage companies, rather than a few large investments in later-stage companies. Investing early allows us to obtain an equity stake that mitigates some of the risks involved with investing at this stage. We seek to generate a large enough individual return for the Fund to balance the portfolio’s anticipated losses and provide our investors with the national average rate of return.Source (opens in a new tab)
