Tailor made service to your needs, very responsive team and bi-monthly zoom updates. It takes a little time to get running but seems to reach goals within a reasonable timeframe.

Thank you, Shawn. We appreciate the feedback and are glad the team’s responsiveness and collaborative approach have stood out. Building momentum can take time, so it’s great to hear the partnership is moving in the right direction.

If you are looking for a team that actually listens to your vision and delivers explosive results, look no further than Quartile. I’ve only been with them for a few months, and my company, B&KM Farms, is already doing almost 3X the volume we did last year. The growth is just insane. It all started with Juliano Oestreich, my onboarding specialist. He was absolutely amazing and made the transition seamless. He really took the time to understand what I needed, showing the kind of flexibility you just don’t find with other agencies. Now, I have a "long-term team" that I truly consider part of the B&KM family: Leonardo Azevedo: He is remarkably good at his job, but more than that, he’s just so personable and friendly. It makes the work day so much better when you’re working with people who genuinely care. Ligia Nemeth: A total go-getter and the best cheerleader you could ask for. Her energy is exactly what a growing business needs. Adrienne Labes: A true professional through and through. She is so kind and keeps everything running at the highest level. They are so communicative and knowledgeable, but most importantly—they actually deliver. If you want to see the proof, look up B&KM Farms on Amazon or our website bandkmfarms.com. The results speak for themselves. I can only imagine what we’re going to accomplish by the end of the year with this crew in my corner. Thank you, Quartile, for taking my vision and running with it!

Kiersten, this was incredibly meaningful for our team to read. The growth B&KM Farms has seen in such a short period is exciting, but what stands out most is hearing that you feel genuinely supported by the people behind the work. Juliano, Leonardo, Ligia, and Adrienne each bring something special to the partnership, and we’ll make sure they see your comments. Thank you for trusting us with your vision and we’re excited for what’s still ahead.

Our Technical Account Manager, Eric, did a great job throughout the whole introductory period in assisting with our advertising account. We saw strong results through his changes and implementations on Amazon - with focus on growth on year-over-year sales. We feel that Eric put us on the right path to continue growing over the next few months. Eric was communicative in meetings, answered all questions, and helped paint a clear picture on the changes to the account.
Response from QuartileMay 27, 2026
Thank you for the kind words, Ryan. We’re glad Eric was able to provide clarity and strong support throughout the onboarding process while helping set the foundation for continued growth. We appreciate your feedback and look forward to building on the momentum ahead.

While the reps and support were great, the overall performance of the account never really improved. Our spend increased significantly while we barely grew. Initially, we thought that it would take some time for the AI to learn our brand and find trends but after over a year, we still saw minimal improvement and canceled our contract.
Response from QuartileMay 20, 2026
Thank you for the feedback, Tony. While we’re disappointed we weren’t able to deliver the level of growth you were hoping for, we do appreciate the acknowledgment of our team and support. We remain confident in the strength of our platform and strategy that has made us the No. 1 ranked retail media advertising platform, but we also recognize that results can vary based on brand, category, and market conditions. We value the time we worked together and wish you continued success moving forward.

Lucas Palma has been a strong partner to work with. He manages our account based on our preferences and input. He keeps us informed as things change, and consistently brings thoughtful recommendations focused on long‑term growth. Lucas provides clear, well‑structured action plans and is very disciplined about tracking performance and identifying where adjustments can improve results. His approach has been both strategic and practical, which we value.
Response from QuartileMay 20, 2026
Thank you for the kind words, Jason. It’s great to hear the partnership with Lucas has felt collaborative and aligned with your goals. We appreciate your trust and are glad his thoughtful, steady approach continues to bring value to your business.
