About Us
Our roots took hold in Switzerland in 1943 and have become firmly embedded as a result of our prestige as a professional and qualified market research institute with a wide range of research services and an unbeatable cost-performance ratio.

In the face of ever-accelerating changes – on the market, in society and technology - we wield the best conceptional and methodical weapons, and strive on the achievement of our carefully-planned goals.
