The deepened partnership promises faster audience activation, higher click-through rates, and lower cost per action.
This strategic investment signals a shift in the German ad tech ecosystem toward combining media activation with AI-powered audience intelligence, addressing the industry's core relevance problem. It also sets a precedent for media groups investing in data platforms to differentiate themselves.

DOOH Growing Structurally — Industry Must Modernize
Tobias Hefele of Weischer says Digital Out of Home (DOOH) is in a strong position, with Nielsen reporting 5.6% growth in the first half of the year versus 1.1% for the overall ad market. He warns the sector is at a turning point and must address measurement, standardization and demonstrable ad effectiveness to secure long-term growth. Hefele highlights opportunities from linking DOOH with Retail Media and from AI — especially AI-assisted creative generation and faster, more flexible campaign processes — but stresses the need to modernize infrastructure and create common standards first. He also notes growing formats such as video, audio and content partnerships, and that both new and existing advertiser segments are fueling structural growth.
