Our brand wanted to move beyond our existing ad strategy and shift into true growth mode—and Lucas made that vision a reality from day one. He quickly bought into the growth mindset and built a thoughtful, targeted plan to get us there.
Since then, we’ve seen consistent, measurable progress across our account. What stands out most is Lucas’s leadership and partnership—he’s proactive, engaged, and genuinely invested in our success.
I really appreciate the attention, strategy, and results he’s delivered. He’s been a strong partner every step of the way.

Thank you, Donn! We are so glad Fabio was able to make things clearer and help you get comfortable with the platform. We appreciate you working with us.
I can highly recommend Quartile's service for Amazon Sponsored Ads and PPC. The set up process was very professional and extremely well managed by Juliano and Nick at Quartile, where our previous ads set up was transitioned smoothly into the Quartile system. Excellent service - both on the software side in its ability to manage the ads, budgets and performance targets, as well as the agency management side which has been very helpful, highly knowledgeable, friendly and communicative. Very highly recommended for Amazon PPC.

Poor performance. Poor Communication.
First they restarted producing Google ads without changing anything. They just put their name in the campaign name. This caused ads to stop producing until they could relearn.
Then they farmed it out to some guys in another country who rarely communicated, ignoring emails.
They didn't understand my business or target market, didn't make any changes to ads or optimize. Then they said that because we had ads already running this was just some sort of review state setup to just monitor ongoing ads.
When I complained about the ad rep not responding or optimizing they told me he has a masters degree. I have no idea what that has to do with not actually managing the account.
Then I asked for my money back and they refused.
Also the rep changed the setting in a campaign to add $ to the revenue when a new customer came from an ad and then claimed we were getting a high ROI when we were not. I brought up these reporting discrepancies with them many times. The person they had me dealing with was in brazil by the way. Emails went unanswered.
They had the opportunity to refund me but never did.

We’re sorry to see this review and would like to provide some important context, as we do not believe it reflects what occurred during our partnership.
This partnership ended in September 2024, so the timing of a review nearly two years later is unexpected and surprising. During that time, you were supported by both an Account Manager and a Strategist, and we maintained consistent communication while working to align on a strategy. Unfortunately, we were never able to reach that alignment, and while that is not the outcome we aim for, not every partnership is the right fit.
To clarify, we did not restart campaigns in a way that would disrupt performance without discussion, nor did we make unauthorized changes to tracking. Access to the account was removed prior to the end of the engagement, which limited our ability to review performance together and address concerns using the data.
We also want to be very clear that every person you worked with was a full-time Quartile employee. We do not “farm out” work, and we stand firmly behind our team. They are dedicated professionals who deserve to be treated with respect, and we will not support assertions that suggest otherwise.
We understand the experience did not meet your expectations, but we do not agree with the characterization presented and stand by the integrity of our team and the work delivered. We do also question the motivation behind leaving this review nearly two years after our services concluded.
Quartile has exceeded our expectations even when managing a 7 figure monthly ad spend budget.

Thank you, Dillon. We really appreciate the trust, especially at that level of spend, and we’re glad to hear we’ve been able to exceed expectations. Looking forward to continuing to support your growth at scale.

I want to take a moment to share my genuine appreciation for the incredible work Fabio have consistently delivered. From the very beginning, they have demonstrated not only professionalism, but also a deep understanding of what it means to truly support and guide clients through every step of the process.
What stands out most is his attention to detail and their ability to listen. He don’t just hear concerns—he actively engage, ask thoughtful questions, and provide solutions that feel tailored rather than generic. That level of care makes a huge difference and creates a sense of trust that’s hard to find.
Throughout my experience, he have been responsive, patient, and proactive. Even in situations that could have been stressful or complicated, they remained calm and solution-oriented, ensuring everything moved forward smoothly. his communication is clear, timely, and always respectful, which made the entire experience feel seamless.
Beyond his technical skills and knowledge, it’s their dedication and genuine commitment that truly set them apart. It’s clear he take pride in his work and value the relationships they build with clients.
Overall, I couldn’t be more satisfied. Working with his team has been a positive and rewarding experience, and I would confidently recommend them to anyone looking for reliable, knowledgeable,
