Ströer

What Ströer does

Ströer SE & Co. KGaA is a publicly listed German media group headquartered in Cologne that combines physical out-of-home (OOH) advertising infrastructure with digital advertising technology, dialog marketing services and data/e-commerce assets. The company was founded in 1990 and today operates three reportable segments: OOH Media (billboards, street furniture, transport media and DOOH screens including Germany's largest DOOH display, "The Whale" in Hamburg), Digital & Dialog Media (online advertising across 1,600+ media brands, the t-online news portal, the Core multichannel SSP and Ströer X business process outsourcing with 45 service centers), and DaaS & E-Commerce (Statista business data platform and AsamBeauty). It reported record preliminary FY2025 revenue of €2,075.1 million (+1% YoY), H1 2025 group revenue of €980 million (+2%), and earned roughly 41% of OOH revenue from digital out-of-home in H1 2025, with DOOH growing 17% and programmatic DOOH growing 26–36%.

The group's revenue model is advertising-led, anchored by enterprise field sales for large brand advertisers (Toyota, BMW, Garmin, Prada, Danone, Ritter Sport, Tourism Australia, AOK) targeting campaigns across billboards, transit, digital screens and online. Programmatic DOOH, audience-based targeting via OS Data Solutions (OSDS), and High-Impact formats (Breakout Ad, Top Scroller, Spotlight Video Ad) are growing rapidly. Ströer X contributes professional-services revenue (Germany's largest BPO provider, AI-supported chat/voicebots) and Statista contributes subscription-like API/MCP data revenue (Microsoft 365 Copilot, Perplexity, Canva integrations). The go-to-market mix spans direct enterprise sales, the Core SSP for programmatic demand, and an upcoming AI-driven self-service layer (Ströer Ad Manager, Q4 2027; Public Mind, 2028) intended to expand the SME customer base from 30,000-50,000 to 100,000 and to project up to €50 million in five-year savings.

Customers include enterprise brand advertisers, SMEs (future), public-sector bodies via democracy/UNICEF campaigns, and AI platforms consuming Statista data. Strategic positioning centers on combining irreplicable urban OOH inventory, a top-ranked domestic news portal, and AI/Statista data infrastructure as a vertically integrated European advertising and data platform; an investor group led by I Squared Capital is reportedly preparing a bid for the core billboard business at a valuation above €3.5 billion.
