Quent.z started as an internal innovation program in the “Powertrain Solutions” Division of Bosch in Germany. After the success of the original idea in the Bosch innovation incubator, it was seen so promising that it was given the opportunity to operate on the market independently.

Bosch still supports the company e.g. by supplying sensor hardware.
