Siewert & Kau Computertechnik GmbH is a founder-managed company. Since beginning operations in 1994, it has been managed by Björn Siewert, Holger Kau and Oliver Kau. The company's strategic orientation and the conception for the development of new business areas and for the introduction of more high-performance system structures is in their hands.

Within this process, the founders are not just managing directors – they are still involved in the operative daily business and place great importance on personal customer contact. In this way, they guarantee that the company remains aware of the requirements and problems of the customers and suppliers. Like all employees, they can also be reached every day and work in the team for the success of the company, in line with the motto of Siewert & Kau: "With our name and in our name, we are there for you."
