OS Data Solutions

The company operates as a data and identity provider within the programmatic advertising ecosystem. It aggregates, standardises and enriches audience and contextual data from first-party and partner sources (such as Ströer inventory and external panels) and exposes this as segments, contextual categories and prediction outputs. Value is created by enabling agencies, advertisers and platforms to plan and execute more precise, privacy-compliant targeting and measurement across programmatic channels.

Commercially, it distributes these data products through integrations with major DSPs, SSPs and other intermediaries, as well as via its own audience discovery interface used for planning and selection of segments. The business model is centred on data licensing, segment usage fees and related services (such as custom audience builds), rather than owning or operating media inventory. As a wholly owned subsidiary of the Ströer Group, it also enhances the parent company’s advertising offering with structured, scalable data assets.

OS Data Solutions is a Germany-based data and targeting subsidiary of the Ströer Group, originally founded as a joint venture with the Otto Group in 2019. It aggregates and models audience and identity data from Ströer and external partners to power programmatic advertising and targeting across major buying and selling platforms.

The company offers audience discovery, contextual classification, real-time prediction-based targeting and identity-based solutions that are distributed via common DSPs, SSPs and other intermediaries. Revenue is generated by selling data and targeting capabilities to agencies, advertisers and other adtech intermediaries, primarily in the German market, with a focus on privacy-compliant, ID-based and ID-less activation rather than direct media reselling.
