Gustavo from the launch team has been incredibly knowledgeable and helpful. In short order he's been able to get our account humming and our ACOS under control.

Quartile was a great choice for our company when it came time to switch things up. We have seen a difference in our profit margins since working with Quartile. Our account manager takes all information about our business into consideration when creating campaigns and guiding us to success. She listens to what has been successful strategies in the past and what did not work for us. She constantly gives feedback on where we can improve. Our business is better situated to be successful with the help of Quartile.

Oskar T.
Fabio was fabulously effective in driving up sales. Thank you Fabio for the 40% growth year over year. I had gone with other Major "machine learning" and "AI" ad platforms (not mentioning names but first letter of that firm starts with "T") that where triple the cost but did not get the results you got in 30 days. Thanks to the unassuming professional sales team, especially Livia and William for never giving up on contacting me. To the top sales manager that makes sure your CRM is working. You would not have gotten me on board without a working CRM. Thank you to the ownership of Quartile, you run a real good company, and I am grateful for the immediate progress. Thanks to your team effort we will double our sales within 6 months. To the entrepreneurs out there, please know that 95% of all ad agencies are run by moneygrubbing and shameless guys, they have minimum training, no systems and will spend your money aggressively or miss opportunities. Go with Quartile for your own good if you want to drive sales on Amazon.
Response from QuartileAug 18, 2025
Thank you so much, Oskar. We're thrilled to hear about the year-over-year growth you've experienced and that Fabio has had such a strong impact. We also appreciate your recognition of our sales team — Livia, William, and the CRM and onboarding teams work very hard to ensure we connect with the right customers and follow through with real value. It’s incredibly meaningful to hear that Quartile outperformed other, more expensive platforms and that the teamwork and strategy behind the platform are delivering real, measurable results. We’re grateful for your trust and partnership, and we’re committed to helping you reach your goals in the coming months.
