We began our partnership with Quartile with a specific plan based on our previous experience managing tens of thousands of dollars in Amazon ads. Despite our history, Fabio listened to our goals and proposed a different approach based on his expertise. Within a very short period, we saw significant results. Fabio helped us understand that while our original strategy was valid, it was being implemented too early in the process. We chose Quartile for their specialized knowledge, and that is exactly what Fabio delivered.

We’ve had a fantastic experience working with Quartile so far. The onboarding process was smooth, organized, and incredibly helpful, all thanks to Fabio. He was knowledgeable, responsive, and went above and beyond to make sure everything was set up properly and that we understood the strategy behind the platform. Since getting started, we’ve already seen great progress in our Amazon account performance, which has been really exciting for our team. It’s clear that Quartile knows how to optimize and scale campaigns effectively. We’re looking forward to continuing to grow our Amazon presence with Quartile and building on the momentum we’ve already started. Highly recommend their team and platform!

Amazing! Fabio really listened to our business needs and delivered incredible results. Within the first month, he increased our ROAS by more than 5 points without increasing our ad budget. Also suggested logistic improvements to support the total sales. Highly recommend working with him!

We’ve been working with Quartile for a while now, and it’s been a really positive experience. Since Laura started managing our Amazon ads, we’ve seen a big improvement in performance. In just a few months, our sales doubled. We really appreciate the effort and support from both her and the Quartile team. Thank you!
