Working with Stella at Quartile has been such a great experience! From our very first conversation, she took the time to really listen and understand Beia, our goals on Amazon, and where we wanted to grow. She guided us through every step with so much clarity and care, and we always felt like we had a true partner in our corner. The whole experience was a lot more hands-on and high-touch than we anticipated and we are SO excited to enter a long-term partnership with Quartile!

Juliano and Nicholas were great!

The transition from our old agency to Quartile was seamless. Almost overnight we saw our conversation rate increase and the results so far have been promising. The team is knowledgeable and extremely responsive. I am already working to get other retailers' advertising under them.

The team is proactive, professional, and always focused on finding new opportunities for growth. A special mention to Victor, our account manager, who has been incredibly supportive, responsive, and committed to helping us achieve our goals!

Quartile has done an excellent job managing Skullcandy’s advertising across multiple countries. Victor Martino, in particular, has been an outstanding partner—efficiently managing regional budgets while consistently meeting our sell-through expectations and ACoS targets. Victor is highly responsive, dependable, and always on top of key priorities. He uses data effectively to identify opportunities, optimize performance, and make informed recommendations. We’re seeing strong growth across all regions and truly value Victor’s expertise, attention to detail, and commitment to our business.
