TDC Group has historically been Denmark's largest telecommunications company. Following its acquisition in 2018 by a consortium of PFA, PKA, ATP, and Macquarie Infrastructure and Real Assets, the operational business was split into two main entities: Nuuday, which manages customer-facing brands like YouSee, Telmore, Hiper, TDC Erhverv, and Relatel, offering TV, broadband, network, and mobile services; and TDC NET, which owns and operates the physical network infrastructure across Denmark, including mobile masts, copper, and fiber networks. TDC Group, through these entities, continues to play a pivotal role in Denmark's digital infrastructure and telecommunications services.
Serves as the central operational and strategic hub for TDC NET (network infrastructure) and Nuuday (digital services), facilitating collaboration between the entities and overseeing national operations.
A modern office complex located in the South Harbour (Sydhavnen) district, designed to support agile working methods and foster innovation. The campus often includes shared facilities for employees of both Nuuday and TDC NET.
The work culture emphasizes technological advancement, customer-centricity, and collaboration. Given the split into Nuuday and TDC NET, there's a focus on specialized expertise within each entity while maintaining a shared heritage of innovation in telecommunications.
The Copenhagen headquarters is significant as the nerve center for Denmark's leading digital service provider (Nuuday) and the owner/operator of critical national telecommunications infrastructure (TDC NET).
TDC Group's primary operational focus is historically and currently within Denmark, where its entities TDC NET and Nuuday provide comprehensive telecommunications infrastructure and digital services. While direct international consumer operations are limited, TDC NET engages in international wholesale services (e.g., data transit, roaming agreements) and Nuuday's business services might cater to Danish companies with international operations. The group's technological expertise and infrastructure also contribute to global connectivity through partnerships.
