JonDos supplies her customers with tools to assert their right for informational self-determination. Moreover, we would like to demonstrate the marketability of privacy tools. JonDos as enterprise acts as a mediator between users of the anonymisation service JonDonym, the \"JonDonauts\", and the independent operators of the service, the Mix Operators. The basis of our business model is selling the access to the service to the JonDonauts, while paying the Mix Operators for relaying their traffic over so-called Mix Cascades. We develop and provide the software for running and using the service for free, in cooperation with researchers of the german Universities TU Dresden and University of Regensburg.
