Quartile Reviews & Product Details

Working with Quartile has been a major turning point for our Amazon business. In the last 12 months, their platform and team have helped us significantly grow our sales and secure a spot in the Top 10 within our category.

Before joining Quartile, we relied mostly on auto campaigns and had worked with another agency with only moderate results. Quartile brought structure, strategy, and automation to our advertising. Their always-on AI continuously refines our campaigns, leading to stronger performance and lower ACoS over time. Just as important, we appreciate their focus on TACoS—this gives us a clearer picture of how advertising is supporting overall business growth, not just ad metrics in isolation.

Our onboarding process was smooth and well-supported by Marcela, and we’ve since built a great working relationship with our account manager, Andrea. Both have been proactive, responsive, and deeply knowledgeable, which has made a real difference in how confident we feel about our Amazon strategy.

Quartile has become more than just a vendor—they’re a trusted partner. We’re very satisfied with the results and look forward to building on this momentum together. Review collected by and hosted on G2.com.

If we had to point out a downside, it would be the slight learning curve during onboarding and the natural uncertainty around getting matched with the right account manager. But once that relationship was established, it made a big difference and resolved those concerns. Review collected by and hosted on G2.com.

They really provide personalized support, are very attentive to our needs, and respond quickly. Our requests are always respected, and we can clearly see improvements and adjustments reflected in the campaigns in a short time. Review collected by and hosted on G2.com.

It could benefit from more detailed dashboards, especially for performance analysis per ASIN, and the ability to compare results against the same period last year would be very valuable. Review collected by and hosted on G2.com.

Quartile has been a game-changer for us. We've been working with them for 3 years, and their impact on our growth, both on Amazon and Instacart, has been huge. Under Rogerio Bonfim’s leadership, things just keep getting better. The CSM team—Rodrigo, Leonardo, Guilherme, Alberto, Ana, Pedro, Raphael, Luis, and Taroel—are absolute rockstars. They don’t just manage the account; they truly care about making it better every single day.

What really stands out is how easy Quartile is to use. The setup was smooth, and even for people who aren’t super technical, the platform just makes sense. We got everything connected with Amazon and Instacart quickly, and almost right away, we started seeing improvements in our ad performance.

Every week, we check in on our campaigns, and with Quartile’s automation, a lot of the heavy lifting is taken care of. It saves us so much time while still giving us full control over our strategy. Plus, it connects with everything we need—Amazon Ads, DSP, Instacart—so we can take a data-driven approach across all platforms.

But the best part? The people. The Quartile team is next level. They’re not just support—they feel like part of our team. They understand our brand, the challenges we face, and they’re always ready to adjust strategies to keep us ahead. From analyzing trends to fine-tuning bids, they help us make sure we’re not just keeping up with the competition but actually leading the way.

We've been seeing double-digit growth for the past three years, and there's no doubt Quartile has played a huge role in that. They don’t just focus on running ads—they help align everything with our bigger business goals. The transparency, the collaboration, the insights—they all make a real difference.

I fully trust that with Quartile, we’ll keep growing. They’re not just a platform; they’re partners in our success. Review collected by and hosted on G2.com.

One thing that I dislike is that the portal could be a little more clean and straight forward for what you are doing. There are not many downsides to using quartile. You gain time back and can gain knowledge from their team. Review collected by and hosted on G2.com.

all good Review collected by and hosted on G2.com.

The team is highly responsive and worked with us thoroughly to get results on a new product with a new account in our market space. They were very easy to use, implement, integrate, and our frequent meetings allow us to work together well. They lowered our ACOS from 300% to 40% in the matter of 4 weeks - we couldn't have gotten here without them and thank you to Gustavo and Gabriel in the launch/customer support team for all their help!

I have no negative comments about Quartile as they have been amazing to work with. Review collected by and hosted on G2.com.

Quartile has been a fantastic partner since 2021, managing various Amazon accounts and services like PPC and DSP for us. Their understanding of the Amazon platform is exceptional – they truly know their stuff. Review collected by and hosted on G2.com.

While the Quartile platform itself is strong, our experience over the past four years has clearly demonstrated that the quality of the account management team is the ultimate differentiator in performance. We've worked with some excellent account managers who have driven significant results, while others have been less effective. Moving forward, we'd greatly value more in-depth strategic discussions rather than solely relying on status meetings. We are experiencing this more collaborative approach now, and we hope it continues. Review collected by and hosted on G2.com.

Commitment of the representative to solve the problems and make sure to get the best results. The onboarding was easy and the initial stage provided a good insights to the business. The software is easy to use and clear. Review collected by and hosted on G2.com.

Not all the representative all good. We had bad experience with one but when we complained they took immediate actions to rectify it. The next representative is brilliant. Something to consider as a improvement opportunity is the knowledge of the representatives about the platform processes and key date when to do promotions. Review collected by and hosted on G2.com.
