We offer the world’s best research-on-demand. Normally, research takes tons of time or money. We changed that: Simply choose your desired dataset, checkout and start enjoying our top-notch work. No hidden subscription model with additional cost, no stress, no worries!

We use state-of-the-art research tools, we aggregate relevant press data and annual reports and summarize all the data in clear Excel tables. Customer satisfaction is our main goal.

We are Jan-Erik Flentje and Leo Semmelmann from Germany. We met each other while working for a venture capital fund – and we decided to start¬†(the German “big brother” of Researchgermany). Before starting Listenchampion, we were (amongst others) working for the leading, worldwide automotive supplier or one of Germany’s largest banks.
