Precise insights through experienced interviewers and innovative technologies

Each year, we conduct more than 200,000 telephone interviews in all national languages. Our experienced interviewers enable representative surveys and targeted audience studies with the highest quality standards. From extensive multi-year studies for the Federal Statistical Office to topic-specific ad hoc studies and hotline services, we offer a wide range of telephone-based solutions.

With our modern telephony software, your questions are asked not only through outbound calls (we call respondents), but also via inbound calls (respondents call us, e.g., callbacks after missed calls or via phone numbers provided in letters and emails). This positions you as a credible and highly accessible research partner in Switzerland.

With locations in Adligenswil and Fribourg, we maintain a large, multilingual pool of experienced telephone interviewers. Study-specific training, professional supervision, and detailed monitoring ensure the highest quality standards. The selection of addresses and phone numbers from sample registers or professional address brokers enables highly targeted surveys. Our dual-frame approach combines landline and mobile phone numbers to ensure robust samples and high-quality representative surveys.

Telephone interviews can also be easily combined with other survey methods (e.g., online surveys or paper questionnaires).
