Market Research, Usability, Innovation Consulting since 1999 – Selected Milestones


Focus in 2015 is clearly on ethnographic research as well as on innovation projects. We have been deeply involved with autonomous driving, human-interface interaction and car-entertainment as well as with smart-home, application scenarios for private multi-media usage (smartphones, tablets, notebooks, PCs, smart-TV, networked audio systems) and networked medical devices (in labs, clinics and at home): a very instructive and inspirational year.


CURTH+ROTH celebrate the 15th anniversary and the most successful financial year since the foundation. Re-location within Hamburg from Altona to lively St.Georg. We deal intensively with re-positioning and branding topics as well as classical market research, e.g. for financial service providers.


Full service market research and brand consultation in 12 industries – core areas are car clinic studies for electric- and hybrid vehicles as well as qualitative projects in the luxury segment, online packaging test, image studies and re-positioning of brands and products. Plus: Insight-community studies.


Our industry knowledge convinces European clients in life science (diabetes management), financial services (credit cards), consumer electronics (printers), IT, logistics and automotive.


Trend: More and more clients do not opt for classical methods like focus groups and in-depth interviews. They rather want a deeper understanding of their customers’ living environment. We interview consumers at their living room table (in-home interviews, ethnographic approach) or in their working environment and we work often with videos taken by participants.

We investigate customer communication in life science (surgery, diabetes, dialysis) consumer electronics, NPOs, and logistics and analyze the user experience of online shops.
