One Tech Group

What One Tech Group does

One Tech Group GmbH is a Hamburg, Germany-based adtech company founded in 2009 that operates the "One Tech Platform," a unified programmatic infrastructure connecting out-of-home (OOH), digital out-of-home (DOOH), radio, print, and in-store retail media inventories. The platform bundles an adserver (ADSERVER1), a supply-side platform (SSP1, self-described as the first European DOOH SSP), a data management platform (DMP1), and a network management system (NMS1), and integrates with 14+ demand-side platforms (DSPs). The company aggregates more than 200,000 bookable media items from 45+ European publishers across 8 countries (Germany, Austria, Switzerland, UK, Netherlands, Norway, Belgium, Italy), positioning it as one of the broadest consolidated DOOH/OOH footprints in DACH and the Benelux region.

The company serves both media owners (publishers, retail networks, network operators) and demand-side buyers (brands and agencies). Anchor media-owner customers include REWE Group (3,000 screens), Rossmann (1,300+ screens across 500+ stores), MediaMarktSaturn, XXXLutz (1,300+ screens), Intersport (1,300 screens across 400 stores), Obi (270 videowalls across 170 stores), TV Wartezimmer (6,000 screens), and Shell stations (~800 screens via ISM), with brand-side campaigns spanning Unilever Magnum, Bitburger, Cewe, and Sonos. The business model combines platform/SaaS fees, programmatic transaction-based fees, managed services, and professional services (consulting and training), indicating a multi-revenue-stream approach. The company is privately held, founder-led by Managing Directors Daniel Siegmund and Lucas Lingens, and operates without disclosed external funding.

Strategically, the 2023 launch of the One Tech Platform consolidated earlier standalone products, with 2024 adding linear radio integration and 2025 launching a dedicated Instore Retail Media Platform. A rapid sequence of 2025-2026 enterprise partnerships (MediaMarktSaturn in October 2025, XXXLutz in August 2025, Rossmann in January 2026, Intersport in January 2025) signals a deliberate vertical push into European retail media networks, while integrations with Displayce (inventory extension), Advertima (3D computer vision for audience AI), and Hawk (ad verification) extend the platform's technical and ecosystem surface.
