What DeDeNet stands for today …

With over 20 years of experience, 35 employees and their corresponding expertise, DeDeNet GmbH is today an established digitalisation partner for medium-sized businesses in the industrial, retail and services sector. Whether at the company’s location in Ettlingen or in Northeim: DeDeNet customers and their business requirements are always at the focus of all activities – from submission of an offer and project planning to project implementation and after sales support.

An integral element of a partnership on an equal footing is an individual requirements analysis in order to create a sustainable and successful IT solution that helps avoid unnecessary costs and reduce the upkeep of resources required for sales, service and logistics.
DeDeNet’s high standards of service are not just reflected in solution development –
all its employees have their roots in the service domain, which explains their fair and collaborative approach both internally and externally and the very high level of customer and employee satisfaction. DeDeNet’s philosophy is therefore characterised internally and externally by community and mutual trust, as well as commitment and competence of each individual employee.

Moreover, as an SME, DeDeNet is able to respond very flexibly to customers’ wishes. Flat hierarchies in the owner-managed company play a key role not just in the commitment and competence of all employees but also in the fast implementation of customer requests and, consequently, in the rapid development of new capabilities – for a shared growth among partners.



How it all began...

From the first website to a mobile IT solution for optimising business processes – from the outset, the history of DeDeNet GmbH has been shaped by innovation through digitalisation. When the company was founded in 1996 as DeDeNet Internet- und Multimedia-Entwicklungen GmbH, Gernot Dähne and Lutz Döring tuned into the spirit of the time:
As managing director of Ettlingen-based Dähne Verlag, business management graduate Gernot Dähne recognised the necessity for companies to offer their goods and services on the Internet to ensure a technologically and commercially viable future. With his partner Lutz Döring from Echte in Lower Saxony, who had already very successfully programmed and marketed his own inventory management software, the solid foundations for establishing the web agency were laid. After only three years, the number of the employees at the company, which specialises in programming web design in HTML, Java and Flash as well as e-commerce and content management systems for small and medium-sized businesses, had grown from four to ten – and over 100 business customers were being supported all over Germany.
