AdTech expansion Market: Exte opens Hamburg office to enter German market
European adtech company Exte is launching a German operation with a new office in Hamburg to develop business with advertisers, agencies and publishers. Nicolas Poppitz has been appointed Managing Director for DACH & CEE and will lead the local sales and market organisation; Tanja Grünwaldt joins as Sales Director. Exte was formed in 2023 from the merger of Spanish firms Sun Media, Rich Audience and Adpone and combines offerings across contextual targeting and ad formats including display, video, native and CTV. The Hamburg office expands Exte’s European footprint — the company says it already operates in Spain, France, Italy, the UK and Portugal, employs over 300 people from 24 nationalities, and maintains 19 locations in 15 countries. Exte states the local presence aims to grow demand- and supply-side business in the German open web market.
Regional expansion and local leadership hires by an AdTech vendor increase competitive presence and local support in the German open-web ad market but do not represent platform-level or industry-shifting change.
