About PREX


Mediaplus and Plan.Net have combined their competencies in programmatic marketing with PREX programmatic Exchange.

The joint venture takes into account the increasing complexity of the implementation of programmatically controllable campaign building blocks in all media. PREX takes care not only of buying and booking but also the optimization of all programmatically controllable channels. This includes online campaigns across all devices as well as previously classically handled channels such as TV, radio and out-of-home.

The main objective of the joint venture is particularly – apart from assisting in the processing of programmatic campaigns – the close interaction and integrated cooperation of creation, media and data-specific insights across all areas of the Serviceplan Group.

This close cooperation between media, business intelligence, and design agencies in the various Houses of Communication significantly increases the success of programmatic campaigns. It is a key asset which only PREX within the Serviceplan Group can offer in this form.

PREX provides the operational and conceptual basis for this, supporting both the individual agencies and their customers in the design and implementation of data-based campaigns.
