Our story

It all started with technology

TTTech was established in 1998 as a spin-off of the Vienna University of Technology (TU Wien) by Professor Hermann Kopetz, his son Georg Kopetz, and his former student Stefan Poledna.

How can we make safety-critical systems that we use every day in different machines, such as cars, planes, or industrial machinery as dependable and as safe as possible? That was the problem we were trying to solve. We have made good on our promise. Today, TTTech Group unites technology companies tailoring our core technologies to different markets.
