Ströer

Ströer is a publicly listed German media company headquartered in Cologne that operates one of the largest out-of-home advertising portfolios in Germany. The company organizes its business around three pillars: out-of-home advertising, digital advertising, and dialogue marketing, under the tagline "Wir machen Kommunikation." Its out-of-home offering spans traditional formats such as large-format posters (Riesenposter), billboards, and street furniture, alongside a fast-growing digital out-of-home network of public video screens installed in city centres, transit environments, and pedestrian zones. Ströer positions itself as a provider of high-reach campaigns that combine classic and digital inventory to blanket German urban audiences.

The company continues to invest in premium digital innovation, recently launching "The Lighthouse" in Hamburg, which it describes as Germany's first immersive DOOH screen, and it integrates interactive elements such as QR-code activation into its advertising formats. Beyond media sales, Ströer runs digital publishing and dialogue-marketing operations, giving advertisers a cross-channel communications platform anchored by its physical out-of-home footprint. Its inventory is concentrated in major German cities including Hamburg, Cologne, and Berlin, where it manages transit and street-level advertising surfaces at scale.

As a listed group with active investor relations, Ströer combines the reach of a national out-of-home network with digital and data capabilities, making it a central player in the German advertising market and a benchmark operator for street furniture and public-video DOOH across the region.
