Troy L.
Our brand wanted to move beyond our existing ad strategy and shift into true growth mode—and Lucas made that vision a reality from day one. He quickly bought into the growth mindset and built a thoughtful, targeted plan to get us there. Since then, we’ve seen consistent, measurable progress across our account. What stands out most is Lucas’s leadership and partnership—he’s proactive, engaged, and genuinely invested in our success. I really appreciate the attention, strategy, and results he’s delivered. He’s been a strong partner every step of the way.

I can highly recommend Quartile's service for Amazon Sponsored Ads and PPC. The set up process was very professional and extremely well managed by Juliano and Nick at Quartile, where our previous ads set up was transitioned smoothly into the Quartile system. Excellent service - both on the software side in its ability to manage the ads, budgets and performance targets, as well as the agency management side which has been very helpful, highly knowledgeable, friendly and communicative. Very highly recommended for Amazon PPC.
