Thank you, Gregg! We’re thrilled to hear about the lift in sales and the reduction in ad costs—that’s exactly the balance we strive for. We appreciate the trust and are glad the experience has been easy and positive so far.
We started working with Quartile during a very demanding phase of our business, across multiple Amazon marketplaces and with complex product categories. From the beginning, the experience has been professional, structured, and transparent. What really stood out for us was the way Quartile approached strategy and execution — not just “running ads,” but understanding the business context, inventory realities, and long-term growth goals. Communication has been clear, data-driven, and pragmatic, which is something we value highly. We appreciate partners who think beyond short-term wins and focus on building something sustainable, and this mindset was evident throughout the collaboration. A special thank you to Luiz Italiano, who did an outstanding job during onboarding and the transition phase. His level of commitment, calm leadership, and ability to translate strategy into concrete actions made a real difference. He was proactive, responsive, and consistently professional, even under pressure. Overall, Quartile feels like a partner rather than a service provider. If you are serious about scaling on Amazon and want a team that combines discipline with strategic thinking, they are definitely worth speaking to.

Pedro was an absolute pleasure to work with. He took his time to understand our company goals and executed everything wonderfully. He was quick to respond to emails and always on top of timely calls about our current account progress. Quartile as a whole has been a wonderful addition to our company! The quick and easy setup and launch were a huge plus.

Thank you, Mike! We’re thrilled to hear the results have exceeded expectations and that Amazon sales have improved. We appreciate the kind words and look forward to continuing the momentum together.
Quartile is up front and clear about what they are doing for us. They do not try to get you to spend as much as possible on advertising, which some companies could try to do. We have used Quartile for only one month and we are seeing good results. Definitely recommend.
