Working with the entire Quartile team has been great! Cris has weekly and bi-weekly check-ins with us to ensure that our ads are running they way we want them to run.

Our company started working with Quartile in March 2024, optimistic that their services would help drive growth for our Amazon product sales. We had bi-weekly check-ins with an account manager, expecting results. Unfortunately, our experience with Quartile fell far short of expectations. Throughout 2024, our Amazon product sales stayed completely flat month-to-month. Compared to 2023, there was literally zero improvement in revenue. Despite the ongoing stagnation, Quartile did not offer any actionable strategies or meaningful insights to move the needle. After months of lackluster results and no return on our investment, we decided to cancel our service. Here’s where things got even worse: We canceled a full week before the start of the next billing cycle, assuming this would end our partnership cleanly. Instead, Quartile informed us of their 30-day notice requirement hidden in the fine print of their contract. This policy meant we were charged for an additional month of service—despite the fact that no services were rendered, nor were they needed. Quartile refused to negotiate or make exceptions, citing "policy" as the reason. This rigid and customer-unfriendly approach adds insult to injury for a service that failed to deliver results in the first place. To anyone considering Quartile: * Be prepared to comb through their fine print, as their policies will penalize you even if their services don’t work as promised. * Don’t expect flexibility or fairness if you decide to cancel. * In our experience, you could end up paying for absolutely nothing. I wouldn’t recommend Quartile to anyone serious about improving their business. Proceed with caution, and make sure you understand what you’re signing up for because they certainly won’t prioritize your success—or satisfaction.

Quartile is a fantastic advertising agency. Their system is amazing at running analysis and using AI to create the best performing PPC campaigns for Amazon and Google, etc. Our company speaks with their team on a weekly basis as they manage the day-to-day for our advertising campaigns. Their team is very friendly and helpful. Highly recommend them to any eCommerce seller looking for an amazing advertising agency who really knows what they're doing!

Great team and results. We've been working together for 2+ years and I can trust them as a member of my company's team.

We have worked with Quartile for about 2 years and they have been essential to our growth and development. Their management of our Amazon ad spend has been technically flawless and their customer service and professionalism has enabled us to make the right strategic decisions to execute our transformation and growth plan. We highly recommend Quartile to other businesses, large and small!

Quatile managed my AMAZON (US) account starting from 20 November 2024 for approximately 7 weeks. During this time, there was a single sale amounting to less than $100, while the advertising expenses exceeded $1000 along with additional monthly charges. Unfortunately, the outcome resulted in a financial deficit of over $2200 in under 2 months. Quatile claims to utilize its proprietary AI technology, although there are uncertainties regarding the effectiveness of this AI system. I will not recommend this company. I would also like to highlight that communication with Lucas has been extremely poor. When I raised the issue of no sale, he wanted to schedule a weekly meeting instead of by-weekly but never eventuated and no response to my emails whatsoever. Therefore I am Not a very happy customer.

Quartile has been managing our Amazon PPC and DSP campaigns for a year. The results have been consistently positive, including increased sales and improved ROI. Throughout this process, Quartile has been providing timely, relevant and impactful feedback & direction in a proactive manner. Both Tiago and Adely have been a pleasure to work with. They exceeded our expectations, delivering significant value and driving continued growth for our Amazon business.

My personal observation on where Quartile stands out is their approach to technology—knowing when to follow obvious paid media trends and when to take a more contrarian approach to solve adtech and ad ops challenges differently from other companies. They've got a strong vision for what their technology platform will do, and I think that stands in contrast with other companies that take a "grouping of point solutions" approach. Besides that, as a team managing a fairly sizable catalog, we’ve found Quartile to be a great match for how we like to run our ad ops.
