Jena: Birthplace of e-commerce and high-tech location with a high quality of life

The Digital Business School headquarters is located in Jena, Thuringia. A majority of professional development events and seminars are held here. That Jena is closely linked to the topics of digitalisation and e-commerce, can be seen from afar: The Jentower is not only the tallest office building of the new Länder, but also the location of the e-commerce solution Intershop - the first e-commerce software worldwide.

The city of about 110,000 inhabitants is also known for the international success stories of Zeiss, SCHOTT, and Jenoptik. Jena is home to international companies as well as numerous small and medium businesses.

Also in terms of culture, sports, and nature Jena has much to offer.

The Digital Business School roof terrace is ideal for enjoying the summer festival "Kulturarena". Digital Business School participants can look forward to visiting the pub mile "Wagnergasse". For the perfect end of the working day, a stroll through the Jena Paradiespark is worthwile, as it lives up to its name with lots of greenery, the Saale, the bar "Strand 22" and volleyball courts.
