simple purposeOffer the best web design and development solutions possible.


Tenacity creates tightly branded websites by leveraging Open-Source technologies in order to build a better web.

Having been based in St. Louis, MO, for nearly six years, we’ve been fortunate to be able to work on a wide variety of projects for organizations of all shapes and sizes. And since we are backed by an additional two decades of website building experience, we bring Fortune 500 quality to all of the projects we touch.

Being open-source evangelists, we provide our clients with a much greater long-term value than other agencies, who often lock clients into an expensive, proprietary solution. We want you to come back to us because you want to, not because you have to.

Our goal is to take the headache out of building your website or application and combine beauty with utility, so you obtain the greatest overall value possible.
