Since the inception of the company, the people and their attitudes to the work of GfK have been dominated by three key aspects: responsibility, initiative and a passion for innovation. This applies above all to the founding father of GfK, Professor Wilhelm Vershofen, with whom it all began. In 1934, he formulated the business idea of GfK, which still today represents the quintessential cornerstone on which the success of the company is based and that is: "let the voice of the consumer be heard".
