About Werner & Mertz
Werner & Mertz is a German YouTube channel run by the Mainz company behind the Frosch cleaning brand. It publishes long-form interviews and panel talks on climate, the circular economy and resilience, most notably the Die Zuversichtlichen series, along with short product demo videos. Uploads come about ten times a year.
The audience appears to be mostly German-speaking viewers over 35 who follow sustainability topics. These figures are estimates based on the channel's content and metadata, not platform analytics. Viewer counts are modest except for a few campaign videos that reached several hundred thousand views.
Brands focused on eco-friendly household products or recycling campaigns can use the channel for high-trust messaging. At a rate of $20 to $35 per 1,000 median views, the typical CPM is well above the $10 CPM common for paid ads, so the channel suits targeted rather than mass reach.
