QuartileReviews of quartile.com

Working with Augusto from Quartile has been a great experience. He is extremely organized, has a strong understanding of our business and products, and consistently delivers comprehensive reporting that gives us clear visibility into our advertising performance on Amazon and other retail channels. We’ve been very happy with the work Quartile has done for us over the past few years.

Weekly updates from Stella is really great. She managed to achieve an exceptional job and our expectations. I really appreciate her giving her insights but also giving us an avenue to also raise our concerns and insights.

Guilherme is a great consultant and stays on top of my ad spends, budgets, and goals each week. The weekly Teams meetings are invaluable to make ad adjustments as needed.

Quartile's onboarding process has been seamless. Gustavo and his team have explained in great detail how the ads are performing and advised on what can improve sales going forward. My sales have increased in a short amount of time, and I am looking forward to a long relationship with Quartile.

Diego, our rep, is very helpful and always looks into things for our account. We've reached the ROAS we initially hoped to and are working towards increasing the budget while maintaining that

Working with Quartile has already proven to be a turning point for our Amazon strategy. Even though we're still at the early stages of our partnership, we’re already seeing solid improvements across all key performance indicators, including ROAS, ACOS, and TACOS. If the current momentum continues, we’re confident that we’ll reach (or even exceed) our growth goals for the year ahead of schedule. A special thanks to Marina Sacramento, our dedicated account manager, whose expertise, strategic mindset, and hands-on support have been instrumental in driving these early results. Her proactive communication and deep understanding of the Amazon ecosystem truly set her apart. Quartile brings a unique mix of data-driven intelligence, personalized attention, and a collaborative approach, making them a highly valuable partner for any brand looking to scale effectively and sustainably.

If it weren't for Augusto we wouldn't be with Quartile! Over 3 years of Amazing Service. Thank you!

Their prompt communication and clear commitment to quality make them a strong choice for anyone considering their services.
