    City

    We’ve got a cool new office in a cool new location. The Alster lake in Hamburg, northern Germany, is one of the city’s incontestable highlights. Right outside the main city center, it’s a key hub for all the city action – and the year-round picturesque photos. Needless to say, that’s why we wanted our office to look out onto these iconic Hamburg scenes.

Our colleagues always tell us how good they feel when they can see their hard work and ideas directly impacting our daily business, and we wouldn’t have it any other way. And because we know how hard our team works, regular team events are an absolute must for us. We’re strong believers in flat hierarchies, flexible working, and achieving that all-important work–life balance.
