Hi! I'm Radosław Mentel.

About me

For over 17 years I've been helping brands grow in the digital world. I'm a certified Google Analytics and Google Ads expert, and an official Google Partner.

My expertise isn't just business practice - it's also teaching. For over 7 years I've shared my experience as a lecturer at the Warsaw School of Economics (SGH), and as a judge of the prestigious semKRK Awards I evaluate the best campaigns on the Polish market.

Looking for support with analytics, want to tighten your sales funnels, or scale your business with precise online advertising?

Get in touch - let's talk about your goals.
