What is T-REX?

T-REX is a non-profit innovation and entrepreneur development center dedicated to strengthening the economic vitality of St. Louis, one startup at a time. Like a magnet, T-REX attracts innovation to our core downtown region. A coworking space, technology incubator, and entrepreneur resource center; we offer an ecosystem where ideas are conceived, brought to fruition, and given room to grow. We’ve worked to create an environment that serves as a network of creativity and support, where abstraction finds clarity in the midst of a collection of bright and dedicated minds. Hovering above a vivacious, animated city, we’re now home to a growing community of well over 400 founders, developers, designers, mentors, educators & more. Want to be a part of the action? You’re in luck – We Welcome All Ambitious Minds.

In our first form, our tech incubator occupied part of the Railway Exchange Building downtown.
(Technology Entrepreneur Center @ the Railway Exchange = T-REX — get it?)

Just like the startups we support, we ourselves have grown and evolved over time. Our name is not just a cool moniker, but an important part of our history – we are still a group committed to growing gigantic companies from the ground up, beneath the St. Louis skyline.
