I’ve had the pleasure of working with Friedolin for the past year and he has consistently impressed me with his analytical and data-driven approach to CRO. Friedolin did in-depth research, identified the right opportunities, and turned them into experiments that delivered strong results and meaningful conversion uplifts.

I worked with Friedolin for the best part of six years at CareerFoundry. When I joined, he was the only marketer in the building. By the time we were done, the company had grown from just over €1 million in revenue to somewhere around €25 million, and he was a big part of why.

Friedolin is extremely structured and always backs his thinking with data. His research, hypotheses and experiment plans were clear and easy to follow. He improved the performance of our hero Google Ads landing page for Online Tutoring across 7 languages. This drove a double-digit reduction in CAC further down the funnel.
