T-REX Innovation Center is a startup incubator, co-working space and professional meeting facilities located in Downtown St. Louis.

In addition to serving as the headquarters for more than 180 startups, T-REX is home to several Entrepreneurial Support organizations who mentor small businesses and startups (Veterans Business Resource Center, ITEN, GeoSaurus) as well as organizations who provide funding for them (Arch Grants, SixThirty, Cultivation Capital).

By inherently eliminating barriers to access these organizations, T-REX companies are able to easily acquire the help and resources they need to grow their businesses.

T-REX is a nonprofit that is firmly rooted in its mission to incubate scalable tech companies in hopes of them outgrowing the facility and basing their business elsewhere in the St. Louis region.
