T-REX serves as a hub for innovation in downtown St. Louis, bringing together entrepreneurs, startups and partners to catalyze business growth that drives economic impact. The nonprofit technology and innovation center operates with a mission-first approach: Help companies grow without taking equity while fostering a collaborative environment for long-term success. Supported by St. Louis Development Corporation (SLDC), T-REX plays a key role in strengthening the city’s entrepreneurial ecosystem.
Originally housed at the historic Railway Exchange Building—where its full name, Technology & Railway Exchange, originated—the organization now operates out of its building at 911 Washington Ave. The center provides space, programing and resources for businesses across multiple industries.
