MediaMarktSaturn expands store retail media offering to eight European markets with One Tech Group

One Tech Group and MediaMarktSaturn are expanding their partnership, which launched in October of last year. In addition to the existing offering in Germany and Spain, the in-store retail media inventory of the European consumer electronics retailer is now also programmatically available in six additional European markets.

The network will comprise around 738 stores and approximately 53,672 screens with 68 million contacts per week. 

For advertisers, campaigns can be centrally managed via One Tech Group’s ad server (ADSERVER1), while inventory can be marketed and booked programmatically via the supply-side platform (SSP1).

Since 1st April, Austria, Switzerland and Turkey have been connected to the One Tech Group platform. From 1st May, three further countries - Belgium, Luxembourg and Hungary - will follow. The newly added markets comprise 300 additional stores and 23.5 million contacts per week.

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. This allows advertisers to integrate their campaigns into existing programmatic workflows and benefit from precise targeting capabilities directly at the Point of Sale, where purchasing decisions are made.

The integration with DSPs also allows in-store retail media campaigns to be more effectively aligned with digital activities and executed using consistent audience targeting logic. This environment is particularly relevant for advertisers who wish to reach tech savvy audiences directly within the shopping context.

“By expanding our in-store retail media offering across Europe, we are making reach at the Point of Sale predictable and actionable for advertisers across national borders,” says Boris Prondzinski, Managing Director at MediaMarktSaturn Retail Media & Partner Marketing.

“Together with the One Tech Group, we are thereby strengthening a channel that reaches consumers directly in the shopping environment and can increasingly be integrated into data-driven omnichannel campaigns. In this way, we are creating a unique platform for brands that want to reach their target audiences in physical stores across Europe.”

Daniel Siegmund, Founder and Managing Director at One Tech Group, says: “The expansion of the MediaMarktSaturn inventory to a total of eight European markets emphasises the momentum in the in-store retail media sector.”

“This expansion gives advertisers access to one of the networks with the widest reach in Europe. The combination of high frequency, targeted audience engagement and international reach makes this inventory an exceptionally attractive component for both local and pan-European campaigns.”

2026 RTIH Innovation Awards

Retail media will be a key focus area at the 2026 RTIH Innovation Awards.

The awards are now open for entries and celebrate global retail technology innovation in a fast moving omnichannel world.

Our winners will be revealed at the 2026 RTIH Innovation Awards Ceremony, taking place at The HAC in Central London on Wednesday, 4th November.

Check out our 2025 winners here.

Our 2025 hall of fame entrants were revealed during a sold out event which took place at The HAC on 16th October and consisted of a drinks reception, three course meal, and awards ceremony presided over by award winning comedian, actress and writer Tiff Stevenson.

In his welcome speech, Scott Thompson, Founder and Editor, RTIH, said: “This is the awards’ fifth year as a physical event. We started off with just 30 people at the South Place Hotel not far from here, then moved to London Bridge Hotel, then The Barbican, and last year RIBA’s HQ in the West End.”

“But I’m conscious of the fact that, to quote the legend that is Taylor Swift, You’re only as hot as your last hit, baby. So, this year we’ve moved to our biggest venue yet, and also pulled in our largest number of entries to date and broken attendance records.”

He added: “This year’s submissions have without doubt been our best yet. To quote one of the judges: The examples of innovative developments across both traditional and digital retail spaces were truly remarkable.”

Congratulations to our winners, and a big thank you to our sponsors, judging panel, the legend that is Tiff Stevenson, and all those who attended our 2025 gathering.
