Supercharge your
marketing effectiveness
Thanks to Cronbach, we understand better why people become enthusiastic about car sharing and how we can specifically increase relevance - throughout Europe.
With the knowledge of what drives non-buyers to buy, we can develop measures that also convince those who don't know today that they will love our products tomorrow!
Cronbach generates real data-based insights that were previously unavailable to me in my work.
DATA + PSYCHOLOGY:
YOUR MARKETING POWERHOUSE
A unique approach to understanding target groups that combines scientific validation with practical feasibility.
This enables us to act more differentiated, focused, and above all, effectively in a very dynamic environment.
We’ve seen significant uplifts already in the first campaign. Not only click rates, but all sales figures in our own shop were convincing.

Our Founders
OBSESSED WITH CONSUMER PSYCHOLOGY
Joost is an expert in consumer psychology. During his time at the Hamburg agency Jung von Matt, he laid the foundations for our understanding of psychology in marketing in order to increase the efficiency of communication. On top of that Joost was also Dean of Business Psychology at the Fresenius University of Applied Sciences in Hamburg for 13 years. In 2024 Joost decided to focus entirely on Cronbach and its spin-off True Relevance.
