Great team to work with. Very responsive. Eric is very attentive to our account and helped our sales grow after he takes over our account.
Thank you Eric !

We have been using Quartile for over a year and a half now, and we have absolutely no complaints. Their team is well equipped to handle any idea we have. Carolina and Adrienne specifically have helped us build amazing Google Ads campaigns that continue to perform very well with fantastic ROAS. Our regular check-ins help us stay on track of our performance and allow us to pivot if needed. Everything is very transparent as we can look into the results ourselves.

Eric was great on-boarding our account and getting us headed in the right direction. I look forward to the next step of the process and seeing how much further we can grow.

Our results have been fantastic in just a few short weeks, all thanks to Eric. The platform is robust and offers a wealth of features. We're excited to see the long-term potential.

Great communication from the onboarding team. Very responsive, hands-on attention, and open to custom requests.

Quartile’s automation has streamlined our bid management and keyword harvesting. Since onboarding, we’ve seen consistent improvements in ROAS, ACOS, and overall campaign efficiency, and we’re already on track to reach our sales goals. Our CSMs are friendly, responsive, and highly professional—they keep us informed with detailed weekly updates.

Two Quartile ad experts took my account and surprisingly and so quickly transformed it into a winning marking strategy.

These guys are great, Luiz and Gabriel have been a huge help and have been walking me through every step of the process. Sales are increasing and my bosses are thrilled! Quartile is definitely one of the best investments we've made this year!

Good onboarding and first few weeks with the Quaritle team. Good service, communication and results! Gustavo and Gabriel have been great, and our Amazon ROAS & sales are much improved.

I rarely leave 1 star reviews, but this one truly deserves it.

I stayed for the trial period paying around £500 a month, they were spam calling me for months prior to joining - I should've seen that as a red flag.

My account manager was completely clueless about my products & failed to target the right audiences, therefore tanked my ads and wasted a lot of money in the process.

Once I mentioned canceling to my account manager, he completely stopped replying to my emails & failed to show up to our meeting, which is the second time.

I'm still waiting for them to cancel my subscription & refund me.

I had a better experience with Xmars (now Xnurta) and will probably go back to them.

We've appreciated the support and insights provided by the Quartile team. Mariana, in particular, has been an outstanding point of contact — she's responsive, knowledgeable, and genuinely invested in our success. The platform’s automation has helped streamline our Amazon PPC efforts, and the regular check-ins keep us aligned. We’d love to see even more proactive insights based on performance trends and clearer attribution of how specific optimizations impact our results. Overall, it’s been a strong partnership, and we’re excited to keep building on it.

This company's professionalism and teamwork are outstanding. If I could describe my experience with them in one word, it would be success.

Great tech, good people, seamless onboarding experience 👌🏼

The team at Quartile has been very pleasant to work with. The knowledge and understanding with the ability to budget accordingly have contributed to the trust we place in their ability to perform. I look forward to continuing our growth trajectory as a true team effort.

We hired them to manage our Amazon Seller Central account. They are pleasant to work with and care about their clients' performance.

We've been very happy working with Quartile. Gabriel and Gustavo have been incredibly helpful and responsive, consistently providing valuable insights and support. Since partnering with them, we've seen steady growth in our sales, and we're excited to keep building on this momentum. Looking forward to even better results ahead!

Excellent Service (Gustavo) and Consistent Results
We've had a great experience working with Quartile. Their team provides outstanding service, and we’ve seen clear, consistent results month after month. They’re responsive, knowledgeable, and truly committed to helping us grow. Highly recommended!

They were very responsive and able to adjust our strategies on the fly. Very helpful and knowledgeable

I would say I'm fairly satisfied with the software. though it has some technical discrepancies, It's very transparent and has tools that really help in some high level decision processes. Though currently an inevitable work in progress, considering our working relationship, the data derived from the software and some improvements that will be and have been made over time, I would recommend this software and company.

I have been using Quartile's Amazon PPC service for 14 months. When I started with them, my ACoS was over 30%, killing my margin. It took a few months to dial in the keywords and bidding, but eventually my rep was able to bring my ACoS down to under 20%. I have stayed on as a customer because I feel they are continuing to bring value to my company.

I started with one representative, and he stuck with me for over a year before being promoted, now I have a new rep. It's worth noting that employees stick around at Quartile. That speaks to how they treat their employees, in my opinion. I have used other PPC services before that had me meeting a new rep every few months.
