BPA Trend Study (Germany, continuous tracking)
The client requires a consistent, reliable view on public opinion in Germany, with a particular focus on how key policy areas are perceived and how government performance evolves over time.
50,000 interviews in 2024, 30,000 in 2025
Large-scale Entrepreneurship Tracking (Germany)
Understanding entrepreneurial activity in Germany requires continuous, large-scale, and methodologically robust data collection. The client needed reliable data on start-up activity and entrepreneurial dynamics, insights into both actual founders and latent potential entrepreneurs, and a large representative sample to capture a relatively rare population while maintaining statistical reliability and comparability over time. Entrepreneurship research is particularly challenging due to the need to identify and screen rare target groups within the general population.
20,000+ interviews completed every year
Large-scale Media Measurement Study
Bavaria's local radio and TV ecosystem requires reliable, granular data on audience reach, usage behavior, and programme perception to sustain competitiveness in a rapidly changing media landscape. The client needed robust audience measurement for dozens of local broadcasters, reliable reach metrics and qualitative programme evaluation, insights at a high regional granularity (district and broadcasting area level), a methodology capable of delivering consistent, year-on-year comparability, and operational execution at very large scale within a tight fieldwork schedule. Media measurement in this context is particularly demanding, as local broadcasters depend heavily on precise regional insights, and results directly influence advertising markets and strategic programming decisions.
