One Tech Group scales in-store retail media to eight markets

One Tech Group and MediaMarktSaturn are further expanding their cooperation in the area of in-store retail media, which was launched in October 2025. Following a successful launch in Germany and Spain, the electronics retailer's inventory will now also be available programmatically in six other European countries - a total of eight stores.

From DACH via Southern Europe to the Benelux region

Austria, Switzerland and Turkey have been connected to the One Tech Group platform since April 1. Belgium, Luxembourg and Hungary will follow on May 1. According to the companies, the newly added markets alone comprise 300 additional stores and 23.5 million contacts per week. The overall network will then comprise around 738 stores and around 53,672 screens with 68 million contacts per week - making it one of the largest programmatically usable in-store retail media networks in Europe.

This means for advertisers: In future, stationary reach can also be planned and used more easily as part of international campaigns. The One Tech Group platform allows campaigns to be managed centrally via the ADSERVER1 ad server; the SSP1 supply-side platform enables programmatic marketing and booking of inventory.

Programmatic access via leading DSPs

The inventory is connected to key demand-side platforms via One Tech Group's SSP1, including The Trade Desk, Active Agent, Hawk, Adform and StackAdapt. Advertisers can thus integrate their campaigns into existing programmatic workflows and benefit from targeting options directly at the point of sale. The environment is aimed in particular at advertisers who want to reach tech-savvy target groups directly in the purchasing context.

The expansion is also intended to make stationary and digital touchpoints along the customer journey more closely interlinked. MediaMarktSaturn is thus positioning in-store retail media as an omnichannel component that can be integrated into data-based campaigns.

Boris Prondzinski, Managing Director at MediaMarktSaturn Retail Media & Partner Marketing, explains: «With the expansion of our in-store retail media offering in Europe, we are making reach at the point of sale plannable and usable for advertisers across national borders.»

Daniel Siegmund, founder and Managing Director of One Tech Group, adds: «The expansion of the MediaMarktSaturn inventory to a total of eight European markets underlines the dynamism in the area of in-store retail media. This scaling gives advertisers access to one of the widest-reaching networks in Europe.»
