Auvionis is a platform for managing digital signage, in-store audio and retail media from one system. Developed by BySide GmbH i. G. in Reken, it is designed for businesses and organisations that communicate with people at physical locations, including retailers, restaurants, fitness studios and public institutions.

The platform brings images, video, information, music and spoken announcements together across screens and speakers. Users can create playlists, schedule content by time and location, and manage multiple sites centrally. A compact player connects to a screen and stores content locally, allowing playback to continue during internet outages. Remote maintenance, status checks and updates are also supported.

Auvionis includes retail media capabilities for making defined advertising spaces available to brands and suppliers, with campaign playback records and control over which advertisers appear. The company notes that this feature is most viable for larger networks, while signage and audio can be used from the outset. Platform and data operations are based in the EU, and music licensing costs are shown separately.
