Where it all started. The managing director and owner Kay Gerlach founded the company TSI in the tranquil Zeven in Lower Saxony. The company headquarter was built especially for TSI – modern & futuristic. In this location, the employees take care of back-office activities, logistics, purchasing and other supporting services.

In 2012, the Berlin office was opened – the TSI Innovation Center. In the second office, product development, sales & marketing, as well as the activities around the management of the main activity fields are located.

In the beating heart of the old quarter in Aarhus lies the cozy office of TSI-Nordic, the Scandinavian division of TSI. The office in Aarhus has its focus on business from the Danish/German border and up, providing support and distribution as well as doing sales and product development.
