Our Story

Three engineers met at Poznań University of Technology in 2009. Bias: ship something real, then make it better. In 2012 they won Poznań Hackfest, earned a coworking desk, and founded Apptension on August 21.

App for what we build. Tension for the friction that turns ideas into production software. We later founded Teamdeck from running our own teams. That product DNA still shapes how we ship.

Since 2012: 30+ senior engineers. 360+ projects. Hackathon speed, enterprise discipline.
