About blackned

blackned GmbH, which was founded in 2009 by the managing director Timo Haas, offers industry-specific software and hardware products, services and customer-specific solutions in the field of dedicated, highly mobile and tactical communication networks.

As a medium-sized privately-owned company, we offer services and products specifically tailored to our customers, which differ significantly from our competitors. Our team consists of numerous highly qualified IT and communication specialists who deal with the latest technology on a daily basis. The modern and flexible corporate structure of blackned GmbH enables a highly dynamic allocation of resources and promotes the transfer of expertise between the business areas.

blackned GmbH consists of two main business areas, the “Products” business unit, which specialises in the development of end-user-oriented software and hardware products for mission- and business-critical applications, and the “Projects” business unit, which is responsible for on-time and on-budget project execution.

The projects include the planning and integration of complex IT and communication systems, the implementation of technology studies and ICT consulting. Our advice is independent of the manufacturer, always tailored to the needs and requirements of our customers. With these two divisions, we can offer our customers an all-around full-service package.

The establishment of a large international partner and customer network and the realization of various IT projects at the highest level for companies as well as public authorities are a special feature of the success of our business concept. This is confirmed by the considerable growth and continuous development that the employees and the products have experienced since the foundation of the company.
