125,000 Screens Now Part of Unified Retail Media Stack

For marketers, the fragmentation between digital advertising and physical retail has been a persistent hurdle. ZetaDisplay’s acquisition of retailmediatools promises to unify these channels, giving retailers control over ad serving from mobile to point-of-purchase, while preserving first-party data. This could revolutionize retail media network strategies by enabling closed-loop measurement across the entire customer journey.

On July 14, 2026, ZetaDisplay announced the acquisition of retailmediatools, a Berlin-based SaaS platform founded in 2021 that provides modular retail media infrastructure. The deal combines ZetaDisplay’s managed network of over 125,000 digital in-store screens with retailmediatools’ MACH-based (Microservices, API-first, Cloud Native, Headless) technology, creating what the companies claim is “the first fully integrated retailer-owned media ecosystem.” This move signals a pivotal shift in the retail media landscape, where the separation between digital advertising and physical store influence has long been a barrier to true omnichannel execution.

ZetaDisplay’s acquisition of retailmediatools promises to unify these channels, giving retailers control over ad serving from mobile to point-of-purchase, while preserving first-party data.

The acquisition arrives at a time when retail media is one of the fastest-growing advertising segments, driven by the need for first-party data and the deprecation of third-party cookies. Retailers have increasingly sought to monetize their physical footprints by selling ad space, but the fragmentation of ad-serving technologies, campaign management tools, and in-store display networks has made integration costly and complex. By acquiring retailmediatools, ZetaDisplay—a company historically focused on digital signage infrastructure—gains a software stack that spans ad serving, campaign management, first-party audience building, and real-time in-store execution. The platform already supports blue-chip European retailers such as Finnish cooperative SOK and drugstore giant Rossmann, proving its ability to scale across diverse enterprise environments.

From a market perspective, the combination directly addresses the demand for retailer-owned media. Unlike third-party retail media networks that siphon off advertiser relationships and data, this integrated solution promises retailers full ownership of their media business, including customer data, advertiser relationships, and margins. The modular nature of the SaaS platform—built on MACH principles—allows retailers to adopt only the components they need, integrating with existing POS, CRM, and e-commerce systems via open APIs. For physical retailers, this translates into the ability to serve ads from mobile and web touchpoints all the way to the store aisle, closing the loop between online impressions and in-store purchases.

The implications are significant. At a network serving hundreds of millions of ads per month, the combined entity can provide CPG brands and agencies with unified, measurable campaigns that bridge the digital-physical divide. This could accelerate the shift of ad budgets toward retail media, particularly in Europe where the market is still maturing compared to the U.S. It also raises the competitive bar for other digital signage and ad-tech providers, potentially triggering a wave of consolidation as companies scramble to offer end-to-end retail media stacks.
