Work at Visonum GmbH

We develop tools to monitor the quality of internet connections across Germany. Our systems track the performance of Vodafone’s cable networks and provide measurement data to Computer Bild magazine for its annual comparison of cellular operators. Millions of people use our web, mobile, and TV apps. In doing so, we actively contribute to improving internet quality in Germany – a contribution we are proud of.
