Klaus Kluth founded B&K together with Peter Bierwirth in 1998. After a successful decade in the field of turnaround management in the hotel business with a portfolio of up to 20 hotels, the duo and the team shifted the business model to the classic development and operation of hotels during the late 2000s. This primarily as operators of international franchise hotels as well as non-branded serviced apartments. By the year 2022, the portfolio had grown to twelve hotels in Germany and Austria with a total of more than 3,000 rooms, as well as the Science Congress Center in Munich-Garching. Since September 2022, the company is part of the Borealis Hotel Group based in Amsterdam.
