BusinessEnterprise in Germany - Berlin IncThe capital reasserts itself as a business hubConventional wisdom has it that the capital of Europe’s most powerful economy is poor, bolshie, chronically indebted and utterly reliant on subsidies from richer states.The debacle of the construction of the Berlin-Brandenburg airport, completed in 2020 nine years late and more than 4bn euro($4.7bn) over budget, confirmed every prejudice about the city.A political storm is brewing over property firms and rents.Reputations are hard to shed. But Berlin’s business circles are trying.During the tenure of Klaus Wowereit, mayor from 2001 to 2014, no firm in the DAX, the index of Germany’s bluest chips, called Berlin its home.After the DAX’s expansion on September 20th from 30 to 40 companies, five have headquarters in the city.Zalando (an online fashion retailer) and HelloFresh (a pedlar of meal kits) joined three other Berliners, Deutsche Wohnen (one of the beleaguered real-estate firms), Siemens Energy (a spin-off from the engineering giant) and Delivery Hero (a food-delivery darling), themselves recent additions.
