In March 2024, horizoom was successfully certified as an access panel service provider under ISO 20252:2019—the international standard for market, opinion, and social research. The standard and the conformity mark serve as a key benchmark for horizoom across all departments and processes, while also providing customers with a relevant—and objective—signal of quality and trust.
Now, in April 2026, it was time for the periodic surveillance audit to maintain the certification. Auditor Holger Mühlbauer visited us at our new office at Zoologischer Garten and, using a comprehensive questionnaire, transparent system demos, and project walkthroughs, reviewed the organizational structure, employee selection procedures, training and development plans, data management and documentation systems, the diligence and traceability of recruitment, fieldwork and sampling, data security and privacy, quality management, compliance with professional ethics and the GDPR, and much more.
After a good 2.5 hours, the task was complete and a mandatory social media photo was taken. Afterward, we were able to enjoy a sundowner on the rooftop terrace with a magnificent view over Berlin and exchange views on current developments in market and opinion research. We look forward to seeing you again by 2028 at the latest!
