A word from our partners
We teamed up with Flat Circle with a goal of tripling our Meta spend. As a consumer subscription product, this is not an easy task. We managed to achieve our goals and maintain ROAS within a few months. Rok and the team became an integral part of our work flow and a trusted partner
Flat Circle helped us get scale back in markets where we were stuck. Solid team. Real results.
High analytical skills and long-time experience in the media buying world make cooperation seamless. The Flat Circle team efficiently manages every dollar spent and tries to provide clients with a bigger picture and understanding of the advertising industry to realize the true impact of performance marketing on a scale.
Flat Circle helped us turn our Meta scaling and creative testing strategy from a bottleneck into a strength. Our testing is more systematic, our spend is more efficient, and we no longer lose momentum during seasonal transitions. That last one alone has made a big difference for us.
Rok and his team have been amazing to work with. They stay ahead of the curve on advertising platform changes, and make suggestions based on what they see in our industry. Communication and results have been stellar.
Partnering with FlatCircle was a great step in our expansion into Europe. Their team has a deep understanding of the intricacies of European media buying and a sharp focus on smart, effective spending. They were responsive, adaptable, and committed to delivering results.
We Think Like Owners.
Not Agencies.
Most agencies optimize for spend. We optimize for profit.
We embed into your business, learn your margins, and build systems that compound over time. Our clients stay with us because we treat their budget like our own - challenging what's not working, doubling down on what is, and always keeping long-term growth over short-term wins.
