My updated experience with Quartile: After onboarding, my partner Gustavo managed spending and Amazon ranking very well, and I was satisfied. Later, I was switched to another “expert in helping clients maximize success,” but unfortunately, my best-selling product ranking dropped drastically. Previously, the product ranked consistently between #5–15 in its category, but it fell to #56. Although some action was taken after I raised concerns, sales volume came at the cost of profitability, and once returns were factored in, I ended up with a loss — something that has never happened in my 6 years of experience. Now, I am struggling to get back to the sales level I had before joining Quartile. Do I recommend it? If your product has ~100% profit margin — yes. If your margins are tight and require close attention to ad spend — in my opinion, this is not the right solution.

Thank you for your honest and thoughtful feedback! It’s completely understandable to feel some initial nerves with changes to ad spend as our system learns, but we’re glad to hear things quickly stabilized and began delivering the consistent results you were hoping for. We appreciate your trust in the process and are excited to keep building on this momentum!

We have been with Quartile for about 3 months and so far they have met their promised KPIs and goals. I liked working with Gustavo and Gabriel from Quartile as they were on top of things and very responsive. I hope that this momentum will continue as we move forward.
