Optimerch GmbH

In a market full of bad actors, we found Rüstem—a “calm representative”—who starts thinking exactly where others have long since checked out. I feel really supported by the team, and my suggestions and ideas are professionally refined and put to use to drive more success and help us get better noticed. We’ve been working with Optimerch on our Google campaigns for three years now, and for additional markets and concepts, I’d always trustfully reach out to Rüstem. As a contrast to all the other writers, I’m intentionally leaving it at 4 stars. Keep up the great work.

Thank you so much for your help—very professional handling! A strong partner even today. Thomas von Othmerding

We’ve always been happy with our collaboration with Optimerch GmbH. Even after our consulting requests dropped significantly due to weakening demand in the market, we continued to receive professional support. In particular, after a critical hacker attack, the team stepped in quickly. Despite the late hour, they even reached out outside business hours so the issue could be addressed right away. We also appreciated that communication was transparent when a consultant was on vacation and who would handle the coverage. That way, whenever we got in touch, it always felt like we had a reliable, personal point of contact. Overall, we consistently got the impression that they work with the customer in mind and take our concerns seriously. Thank you for your support and for the reliable service. Quality and performance deserve recognition! Thumbs up for the company!

Extensive expertise, especially in SEO/SEA. Nico has given us great advice; we feel we’re in good hands and have been working together for 1.5 years now. Best regards to the Optimerch team
