One Tech Group

One Tech Group operates a publisher-focused software-and-services model. It develops proprietary infrastructure used by media owners to manage direct and programmatic advertising sales, organise network operations, activate audience data and improve yield. The company creates value by replacing fragmented workflows with an integrated stack tailored to one-to-many channels, especially DOOH and OOH, and by offering hands-on operational support where clients lack internal programmatic expertise.

One Tech Group is a German B2B ad technology company that builds software for publishers and media owners operating across digital out-of-home, out-of-home, print and radio. Its platform suite includes an ad server for direct bookings, an SSP for programmatic monetisation, a data platform for audience and inventory activation, and an operations layer for network and sales management. The company also provides managed and advisory services for clients that want outsourced execution or programme build-out support.

The business makes money by licensing its software platform and by monetising programmatic transactions and services. Its direct customers are publishers, media owners, DOOH network operators, ad operations teams and media sales teams rather than consumer users. The value proposition is operational consolidation: helping one-to-many media owners centralise inventory, bookings, targeting, delivery, reporting and yield optimisation in a single stack.
