Madison Dearborn Partners

Madison Dearborn Partners is a Chicago private equity firm with a long-running buyout practice that includes healthcare among its target sectors, alongside financial services and broader infrastructure plays. Within healthcare, the firm focuses on Care Delivery and Tech-Enabled Services and operates at the larger end of the middle market. AI is not a stated thematic priority.

Check sizes are $25M and above at the growth and buyout stage. Madison Dearborn is US-headquartered and invests primarily in North American healthcare assets, though its broader fund activity spans other geographies and sectors. Named portfolio companies and team members in the healthcare practice are not specified in the dataset available here; the firm’s website and prior fund announcements are the better source for current activity.

This is a large-cap buyout shop, not a venture investor. AI founders pre-Series B should not pitch Madison Dearborn. The fit is for healthcare services platforms with substantial scale already in place, founder-owners considering a control sale, or management teams looking for institutional backing to pursue larger consolidation strategies. Expect a process-oriented diligence cycle and an emphasis on financial profile and governance over technology novelty.
