Ströer SE & Co. KGaA is a powerhouse in the German media landscape. At its core, the company is built on Out-of-Home (OOH) advertising. Think billboards, posters at bus shelters, and digital screens in train stations. This isn't a small operation. Ströer commands a massive presence, particularly in Germany, where it controls over 300,000 advertising locations.

If you've ever waited for a train in a major German city, you've seen Ströer's work. The company dominates high-traffic public spaces like transit hubs and bustling city centers, making it a go-to partner for brands wanting to reach a mass audience. But its strategy goes far beyond simply plastering posters on walls.

Ströer's key approach is called the 'OOH-plus' strategy. The 'plus' is crucial. It signifies the integration of traditional physical advertising with a growing portfolio of digital media assets. The goal is to create a seamless, cross-media ecosystem that engages consumers at multiple touchpoints, both in the physical and online worlds.

The foundation is still classic OOH media, like static billboards and street furniture. But the growth engine is Digital Out-of-Home (DOOH). These are the large-format video screens you see in malls, airports, and train stations. Unlike a static poster, DOOH allows for dynamic content, targeted advertising based on time of day, and even interactive campaigns. An airline might advertise cheap flights to sunny destinations during a dreary winter morning, then switch to business travel deals in the evening.

The 'OOH-plus' strategy diversifies Ströer's business into distinct, yet interconnected, segments. This structure allows the company to capture value from more than just ad space. The main segments are OOH Media, Digital & Dialog, and DaaS & E-Commerce.

The inclusion of a data platform like Statista and an e-commerce brand like AsamBeauty might seem odd for an advertising company. However, it's a strategic move. Statista provides valuable data and insights that can inform advertising strategies for Ströer's clients, fitting into a Data as a Service model. Owning an e-commerce brand like AsamBeauty allows Ströer to use its own massive advertising network to build a consumer brand, creating a powerful, self-reinforcing loop.

This integrated model, where physical ads drive traffic to online properties and data from those properties informs the ad strategy, is what defines Ströer's ecosystem. It's a system designed to monetize attention, whether it's captured on a street corner or a webpage.
