Our experience with Quartile has been excellent. We have seen a clear positive impact on our account, and the level of support has been outstanding. Since Bruno Albuquerque took over as our Ads Account Manager, the growth has been even more noticeable. He is extremely committed, attentive, and proactive, and it is clear that he genuinely cares about our results. Working with him has been a great experience, and we truly value his partnership.

Our experience onboarding with Quartile has been outstanding from start to finish. Pedro and the team made the entire process incredibly smooth, organized, and easy to understand, even when navigating the more complex aspects of retail media optimization. Communication was clear, timely, and always helpful, and we felt fully supported every step of the way. What really stood out was their level of professionalism combined with a genuine willingness to go above and beyond to ensure everything was set up for success. It’s clear they care not just about performance, but about building strong client relationships. We’re very excited to continue working together and would highly recommend Quartile to anyone looking to elevate their advertising strategy.

Thank you for the great feedback, David. We’re glad to hear the transition was smooth and that we’ve delivered on expectations. We appreciate your trust.
I worked closely with Marina from the Launch Team, and she has been great throughout the process. She did an excellent job explaining the platform, walking me through Quartile’s reports, and making sure I understood how everything works.She has always been very helpful and supportive. In terms of performance, we’ve seen improvements across key metrics with Quartile AI, including cost efficiency, sales, ROAS, and ad spend. Over the past two months, our KPIs have improved, and it’s clear that Quartile has had a positive impact. It has definitely met my expectations, and I can't wait to see the growth that we'll continue to have with Quartile.
