As you will probably not need us to tell you, times are changing today even faster than they used to. Markets change virtually over night, and what was important yesterday is tomorrow only fit for the dustbin. Some people find this irritating. We, on the other hand, enjoy it. Because being constantly on the move is fun, and new challenges mean that life never gets boring. We take pleasure in finding economic solutions and creating innovations that are not just new, but above all intelligent and useful. To achieve results like that, we sometimes tread on our customers' toes, but we always listen carefully when they talk about their problems and wishes. And we draw on the competence, experience and feel for the market that we have acquired in more than 160 years.

That sums up most of our philosophy. But just one more thing. Not all people who call themselves service providers know what service really is. We do, and we prove it every day. And we are rather proud that we have so far been highly successful in doing so. When you look for STRENGER, it means you are looking forward. You will always find us where nobody is yet quite at home. Leading in new directions.
