Investment thesis

25Madison focuses on harnessing artificial intelligence to modernize legacy businesses across two main strategies. On the early-stage venture side, it incubates and invests in AI-native software and tech-enabled companies through its Studio (incubation) and Ventures (investment) arms. On the buyout side, its Propel strategy acquires and transforms lower-middle market businesses by applying AI. The platform combines company building, direct investment, and transformation buyouts under a unified applied-AI approach.
