What is T-REX?

Like a magnet, T-REX attracts innovation to downtown St. Louis, Missouri. A coworking space and technology incubator, we offer a blank canvas—a space where ideas are conceived and brought to fruition. We’ve worked to create an environment that serves as a network of creativity, where abstraction finds clarity amongst a collection of bright and dedicated minds. Hovering above a vivacious, animated city, we’re now home to a growing community of entrepreneurs, developers, designers, mentors, educators and more. We welcome all ambitious minds. Find Out More!

Yes. We may not be in the Railway Exchange but it is an important part of our history – we are still a group committed to growing gigantic companies under the St. Louis skyline.

"T-REX changed my life. The first time I stepped in the door, I joined a group of strangers and won St. Louis' first Startup Weekend. Since then, we've won or raised over a quarter of a million dollars, quit our day jobs, started generating revenue, and hiring employees to grow our business."

− Drew, CEO of Juristat

"The early days of T-REX will go down in history...this place has always been a dreamland for entrepreneurs."
