## About

Southridge was established in 1996 by Stephen Hicks after he built a track record in merchant banking and structured equity financings. The office manages the capital generated by those activities and continues to execute similar transactions alongside newer strategies. Capital is deployed in direct co-investments, SPVs, private credit, private equity, and secondaries. Confirmed focuses include Healthcare Services, FinTech, Energy Transition & Renewables, Industrial Tech, Media & Entertainment, AgriTech & FoodTech, and SpaceTech. Investments target growth-stage companies and span North America and international markets. Portfolio holdings mix public and private issuers. The office lists no disclosed headcount or additional offices beyond its New York headquarters. Related real-estate holdings sit in Ridgefield and Danbury, Connecticut. Philanthropy is conducted through the Daystar Foundation, where Mary Hicks serves as Secretary and Treasurer. No operational events from the last 24 months appear in public records. Southridge’s structure keeps investment decisions inside the family office while using Tarpon Bay Partners LLC, an entity owned by Hicks, for selected transactions. This setup allows direct control over both operating investments and certain real-asset holdings without external fund vehicles.
