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!
So far it has been a pleasure working with Quartile.Helpful, informative.
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!
Great team!! Shoutout to Pedro for being on top of our set up and onboarding
Quartile has been a game changer for our ad efficiency on Walmart and Amazon. We are the most efficient we have ever been. Our reps, Bruno and Anna, are AMAZING. We have had a lot of changes to our ad strategy and they act quickly and effectively to get them done. They have made my life so much easier when it comes to ads, so I would definitely recommended Quartile for your ad needs.
Amazing experience with the Quartile team so far. Pedro has been professional and timely on all focus points of our business.
Luiz has been very easy to work with during the onboarding process. He is quick to respond, takes feedback, and gives detailed recommendations clearly. Our account is currently up 12% YOY (YTD) and we look forward to seeing how this continues to improve in the coming months.
It’s been great working with Eric.
Amazing to work with!
Responsive, informative and approachable. We have been using Quartile for around 10 months and as a small business we have seen growth in different areas across our Amazon platform and with Google Ads, our sessions are always backed with data, analysis, there are a host of tools that are available on the platform. Pricing is transparent and we got some great intro deals and offers which helped us to trial them for the first few months, I also appreciated their onboarding process which was reassuring and informative. Our account manager is informed, connected and we have regular meetings which give us great guidelines and suggestions on branding awareness, growth strategy and anything else on our mind. We have enjoyed working with them and accessing their knowledge and resource in guiding our advertising strategies and continue to work with them as they help us reach our target audiences.
After completing the onboarding, I'm very satisfied with Quartile thus far, and looking forward for a long term relationship with them. They are quick, communicative, and to the point. They understand the urgency of the client and are ready to execute.
These guys are masters at their craft, Fabio has been great with communication and most of my advertising metrics have gone up since working with them

He keeps a close eye on performance and regularly suggests improvements. We are happy with the results!Communication is always clear and quick, and overall the support has been very solid.
Gustavo was fantastic, very proactive and wanted to learn my business to ensure that the set up maximized the utility. Very happy!
I'd like to acknowledge Quartile and very specifically, Alexandre, who has helped navigate and stabilize our AMZ marketing efforts with PPC and DSP the past year.
Exceed my expectations for our Amazon account. More than doubled our average sales using the same ad spend as our previous advert management firm.
I've been working with Quartile for years. They make running our Amazon Ads simple and easy. Alexandre listens to our needs, makes suggestions, and works with me to crush our goals. Our Amazon ads are the most optimized they have ever been.
We’ve had a great experience working with Quartile for our Amazon advertising! The results truly speak for themselves.
