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.

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.

We have recently launched our Brand on Amazon US Marketplace. Quartile Team Members Pedro and Gabriel gave a good initial start for our brand. Looking forward for greater collaboration in coming days

Quartile has been an absolute game changer for us at Spread The Love. Since partnering with them, our sales are up and our ACOS is down significantly — the kind of results we’ve been striving for but couldn’t quite hit on our own. A huge part of this success comes down to our Technical Account Manager, Fabio Brauner. Fabio has been outstanding — proactive, detail-oriented, and always willing to dig into the numbers with us. His expertise and responsiveness make us feel like we have a true partner invested in our growth, not just another vendor. Quartile’s platform combined with Fabio’s support has taken our Amazon advertising performance to the next level. We highly recommend Quartile to any brand looking to scale smarter and achieve measurable results.

From start to finish, the communication and guidance were absolutely flawless. Marina and Alexander made the entire process feel smooth, transparent, and comfortable. They walked me through every stage with patience and clarity, always making sure I felt confident about the next steps. Not only are they super professional, but they also bring a personal touch that’s rare in this kind of business. You can tell they genuinely care about their clients' success, and that makes all the difference. I’m really happy with my experience and highly recommend working with Quartile, especially if you value great support and results. Muchas gracias Marina and Alexander!
