About Us

Who We Are

We specialise in ad-hoc market research and are an established partner of over 100 national and international brands.

Opinion stands for passionate market researchers with expertise, experience and enthusiasm. With around 30 permanent employees, we are small enough to be flexible and large enough to realise every project smoothly. We have many years of experience in coordinating and managing international studies: over 60% of the studies conducted by OPINION are international.
