A place where people, partnership, and products thrive

That's what we set out to build in 2007, and it's still the idea. We're a close-knit team of engineers and designers just outside Knoxville, Tennessee, turning good ideas into real things.

Built for engineers to do great work, together

Our average time at APTUS is more than ten years. Why? We love working together, and we think you will too. We value competence and creativity, help each other out, and make time to have fun, because balance matters.

The appropriate solution

APTUS is Latin for “appropriate.” Every customer is different, so we shape our approach to fit. A few things never change.

  • We show up for our customers, sometimes even in the company plane.
  • We bring our customers along for the journey, learning and building together.
  • We're straightforward. Honesty always leads to better results.
  • We connect with our customers as people. Strong relationships are the foundation of great work.
