25madison

25madison is a venture and innovation platform that co-founds and invests in AI-native and tech-enabled businesses, and partners with private equity firms to build and transform portfolio companies at scale. The platform is backed by Apollo Global Management and operates from offices in New York City and Miami. Its model combines incubation, venture investment, and transformative buyouts under one structure, supported by in-house technical and operating capability spanning engineering, data science, product design, branding, infrastructure, and go-to-market strategy.

For private equity sponsors, the relevant vehicle is 25madison Propel, a transformative buyout platform that partners with private equity firms to reposition and scale portfolio companies. 25madison Studio co-founds and builds AI-native and tech-enabled businesses, while 25madison Ventures, an early-stage fund, invests from pre-seed to Series A. Creature, the in-house agency, delivers brand, product, and marketing transformation aimed at both immediate impact and long-term equity value.

The platform takes an operator-driven, hands-on approach, blending technical execution with strategic go-to-market and operating capability and working closely with entrepreneurs, design partners, and customers. Sector focus includes healthcare, supply chain and industrials, and AI-driven B2B software. Portfolio companies include 25m Health, Creature, Sift, and SNSE.
