Ströer SSP

Ströer SSP is a multichannel supply-side platform and adtech operation of the Ströer Group, one of the largest out-of-home and digital media companies in Germany. The platform develops and operates a fully integrated, multichannel-capable technology stack that supports the group's digital media formats, spanning display, video, mobile, connected TV and digital out-of-home. Ströer's digital out-of-home inventory belongs to its Public Video product family and has been programmatically bookable since 2018, enabling automated buying of digital advertising space in public environments with precision and efficiency.

The SSP aggregates demand from direct customers, agencies and demand-side platforms, and gives publishers yield-management tools including private deals, private auctions and real-time bidding, alongside controls such as price floors, white and black listing and automated quality assurance. Its private marketplace offers preferred access to premium inventory, and the company operates one of the largest private marketplaces in the German-speaking market, with several thousand actively managed deals and curated, customized inventory packages for digital campaigns. The platform emphasizes quality and safety, applying proprietary traffic filtering, fraud detection and brand-safety measures across large volumes of ad requests to protect advertisers' brand image.

While primarily focused on Germany, Ströer SSP also serves clients in neighboring European markets such as Switzerland, France and Spain. For buyers, it provides programmatic access to Ströer's exclusive premium out-of-home and cross-channel inventory with targeting data and expert support, positioning programmatic digital out-of-home as an automated, precise and accountable part of the media mix.
