Deutsche Giga Access (DGA) acts as a holding company to control and acquire regional fibre network operators. DGA acts as network owner and general contractor for the planning, construction and operation of passive and active infrastructure, which can also be leased by other service providers (open access model).DGA invests in the own-account roll-out of fibre broadband infrastructure in Germany. Where a self-supported roll-out does not make sense, it uses regional funding programmes.

DGA pursues two main business models: on the one hand, it acquires and develops regional network operators with their own network and end-customer business; on the other hand, it offers its network infrastructure to third parties who want to market their products to end customers via the DGA networks. 

Following the acquisition of the Northern Access nucleus, a holding company has been created to structure organic and inorganic growth and will comprise around 60,000 "Homes Passed" by the end of 2022. The aim is to drive forward the expansion of Internet access via FttH (fiber-to-the-home) and to help shape the consolidation of the highly fragmented market for Internet service providers in Germany by acquiring other regional providers in order to build up a market player of relevant significance.
