The TTTech Story

It all started with technology, basic research.

TTTech, which stands for Time-Triggered Technology, 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. Back then, spin-offs with a focus on technology were unheard of in Europe. Our core mission from the outset: to provide reliable computer systems. The basic idea revolved around dependability and real-time safety. How can an overall system keep up safe operation when singular components fail? 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.

Today, TTTech Group unites technology companies tailoring our core technologies to different markets.  There are roughly 2 million cars on the street with automated driving systems based on our technology. Our solutions are installed in more than 10,000 wind turbines that provide millions of  households with clean, sustainable energy. Our networking solutions have allowed airplanes to safely cover more than one billion flight hours while two million kilometres were covered by spacecraft in deep space. Trains, trucks, snow groomers, and many other machines clock in billions of operating hours with our solutions on board. For now, we have made good on our promise to make computer systems worldwide as safe and dependable as possible. But the journey is never over. We are excited to find out where it will take us next.
