Reviewers overwhelmingly had a great experience with this company.

People consistently share that the platform effectively enhances ad performance, resulting in noticeable sales growth and improved efficiency. Consumers appreciate the clear data points and professional guidance provided throughout the entire partnership. However, some people mentioned facing issues with poor communication and a lack of proper responsiveness from their representatives. A few reviewers also felt that the services were rather costly and failed to generate the expected return on their advertising investments.
Auto-generated from all reviews of this business. For reference only.The transition from our old agency to Quartile was seamless. Almost overnight we saw our conversation rate increase and the results so far have been promising. The team is knowledgeable and extremely responsive. I am already working to get other retailers' advertising under them.
The team is proactive, professional, and always focused on finding new opportunities for growth. A special mention to Victor, our account manager, who has been incredibly supportive, responsive, and committed to helping us achieve our goals!
Thank you for sharing your experience, Nuria. It’s wonderful to hear that the partnership is delivering meaningful results while continuing to uncover new opportunities for growth. Victor will be proud to know his support and commitment have made such a positive impact, and we look forward to continuing the journey together.
Seven months with Luiz Monclar at Quartile and our Amazon sales have grown every single month — we've more than 10x-ed our monthly sales since we started. What sets Luiz apart isn't just results, though. He's friendly, dedicated, and incredibly responsive. He answers questions same-day, explains the "why" behind every strategy shift, and genuinely cares about our brands. Working with him feels like having a teammate, not a vendor. Highly recommend.
Thank you for such an incredible review. Seeing your Amazon sales grow more than 10x in just seven months is an amazing milestone, but we're equally proud to hear how much you value the partnership behind those results. Luiz will be thrilled to know that his dedication and commitment to your brands have made such a difference, and we’re excited to keep building on this momentum together.
Quartile has done an excellent job managing Skullcandy’s advertising across multiple countries. Victor Martino, in particular, has been an outstanding partner—efficiently managing regional budgets while consistently meeting our sell-through expectations and ACoS targets. Victor is highly responsive, dependable, and always on top of key priorities. He uses data effectively to identify opportunities, optimize performance, and make informed recommendations. We’re seeing strong growth across all regions and truly value Victor’s expertise, attention to detail, and commitment to our business.
Avi, thank you for the thoughtful review and for trusting Quartile to support Skullcandy across multiple markets. Managing growth, efficiency, and regional priorities at the same time requires a strong partnership, and we’re proud to hear Victor has been delivering on all fronts. We’ll be sure to share your feedback with him and the team.
We've been working with Quartile for several months now and we are very pleased with the results we are seeing in sales. Our Quartile manager Cesar has been excellent in his service and management of our account.
Thank you for sharing your experience. We’re thrilled to hear you’ve been pleased with the sales results so far, and we’ll be sure to pass along your kind words to Cesar. We appreciate your partnership and look forward to continuing to build on this progress together.
Excellent experience from the very beginning. The onboarding process was extremely smooth, organized, and professional. The team took the time to understand our existing Amazon PPC structure and was very considerate about making the transition as seamless as possible, ensuring that nothing we already had running was negatively impacted. Communication was clear throughout the entire process, expectations were well managed, and we always felt supported. Their attention to detail and willingness to adapt to our current setup made the onboarding much easier than expected. Very professional team and a great start to the partnership. Highly recommended!
Thank you for such a thoughtful review. It’s great to hear our team made the onboarding process feel seamless and well supported. We’re grateful for the recommendation and excited about what’s ahead in our partnership.
We've been working with Quartile for several years to manage our Amazon advertising, and the experience has been consistently strong. Our account rep, Victor Martino, has been an outstanding partner. He's highly responsive, brings recommendations that are always backed by data, and takes the time to understand our business rather than just pushing generic optimizations. His strategic guidance helped us grow the account while simultaneously reducing ACOS, which is exactly the kind of efficiency every brand is looking for. If you're evaluating ad management platforms, Quartile's combination of technology and hands-on account support is hard to beat.
Peter, thank you for your continued partnership and for such a thoughtful review. We’re glad to hear Victor’s approach and strategic guidance have helped your business grow. We truly appreciate your trust in Quartile and look forward to continuing to build on that success.
We have spent one quarter with Quartile and had an almost 100% increase over 2025. 96% to be exact. This is crazy growth number. Far exceeded expectations. Leticia Fernandez is an amazing asset and has been wonderful to work with.
Thank you for the great review, Corey. We’re thrilled Quartile has exceeded your expectations so quickly. Leticia will be especially happy to hear your kind words, and we’re excited to see how much more we can accomplish together as the partnership continues.
Quartile enables enterprise-level activation capabilities + strategic support and guidance, for the SMB market. As an emerging CPG brand, our ability to leverage their campaign automation and sophistication has dramatically improved both ad performance and spend efficiency. A no brainer service provider if you're committed to long term optimization.
Thank you for the great review, Kevin. It’s rewarding to know our technology and team have helped bring a more sophisticated approach to your advertising while improving efficiency. We’re proud to support your long-term growth and grateful to be part of the journey.
Gustavo is great, he is helping me scaling my business, consulting so it makes sense for me to join Quartile. Very responsive and friendly. Very excited with the next steps
Paulo, thank you for the kind words. We're glad Gustavo has been a helpful resource as you evaluate the next steps for your business. We’re excited to continue the conversation and see what we can accomplish together.
Guilherme Fumagalli is the man. Changed our account dramatically - worth every penny moving over to Quartile and having them implement their years of experience on our ad account. Couldn't be more grateful. Fantastic reasonable priced partner if you are growing your brand.
Thank you for the fantastic review, Harry! We're thrilled to hear the partnership has made such a meaningful impact on your business. We'll be sure to share your kind words with Guilherme, and we appreciate your trust in Quartile as your growth partner.
Working with Quartile has been an excellent experience. Their team, Rafeala Nunes and Guilherme Fumagalli, has played a key role in helping us grow our Amazon sales through effective, data-driven advertising strategies and ongoing optimization. They are knowledgeable, responsive, and always focused on achieving the best possible results. We have seen significant improvements in our campaign performance and overall sales, and we highly recommend Quartile to any brand looking to scale its Amazon business.
Thank you for your thoughtful review, Ali. We're thrilled to hear that Rafaela, Guilherme, and the team have made such a positive impact on your business. We truly value your partnership and appreciate your trust in Quartile as we continue working together to drive long-term growth on Amazon.
Rafaela has been great to work with, we have had to navigate some changes to our business during this partnership and she has been nothing but supportive. We just had a record month last month on our website and Amazon sales continue to grow. Thank you Rafaela!
Riley, thank you for taking the time to share your experience. Navigating change is never easy, and we're so pleased Rafaela has been a steady partner throughout the process. Congratulations on your record month, and we look forward to helping you build on that momentum in the months ahead.
We’ve been working with Quartile for several years and have been consistently impressed with both their service and results. Our ecommerce business has been operating for more than 25 years, so we’ve worked with many providers over time. Quartile has stood out for their responsiveness, adaptability, and ability to address our unique challenges. Even though team members have changed over the past three years, the quality of service has remained consistently strong. They continue to deliver results within our target range and budget, which has made them a valuable partner for our business. I’ve recommended Quartile to several friends for their own companies and would gladly do so again.
John, thank you for your continued trust and partnership over the years. Knowing that Quartile stands out after 25 years in ecommerce and has remained a reliable partner through team transitions means a great deal to us. We truly appreciate your recommendations and look forward to helping your business continue to grow for years to come.

Thank you, Darlene. We’re glad to hear Bruno made such a positive impact on your experience with Quartile. We’ll be sure to share your feedback with him, and we appreciate your trust in our team.
I have had a fantastic experience with Quartile, more specifically Marina Toro. She was my onboarding specialist who went above and beyond in helping me understand my Quartile portal and all of the ways they are helping us to increase sales while saving valuable ad dollars on Amazon. Before I started working with them, I felt like I was just throwing money into the Amazon abyss. Our sales have grown dramatically while simultaneously reducing our ad spending waste. Now that our account has “stabilized “ I am a little sad that I will not be working with Marina anymore, however I am excited to see how their long term team will continue to help us grow. Thank you Quartile!!!
Tiffiny, thank you for sharing such a thoughtful review. It’s fantastic to hear how much confidence you’ve gained in your Amazon advertising strategy and the impact the partnership has had on your business. Marina will be thrilled to know how much her guidance meant to you, and we’re excited to continue supporting your growth with the broader Quartile team.
No complaints, helped us so so much, great people :)
Thank you, Percy! We’re grateful for your kind words and thrilled to hear that our team has made such a positive impact. We truly appreciate the partnership and look forward to continuing to support your success.
Marina was a pleasure to work with. Knowledgeable and patient. She took the time to understand our business and help guide us through our onboarding process.
Thank you for the review, Andy. A successful onboarding experience starts with understanding a client’s business and goals, and we’re glad Marina was able to make that process smooth and informative. We’ll be sure to share your kind words with her, and we appreciate the opportunity to support your team’s growth.
