Because at the end of the day, your success is what drives us.
We know how to take care of your advertising and revenue through all time periods.
If you just started/restarted your brand we will help you with the strategy, creatives, media buying and building retention with Emails.
As you can see on the right, one of our clients did a rebranding and started working with us on January 1st. We started slow-paced, now scaling every day, based on the performance number we are seeing.

>Important is that you follow your commercial plan and have strategic tactics all over the year so you have stable performance and account. This is the base when the sale/promotion periods come that your audience is already familiar with your brand and are grabbing the best deal you are offering.

Creative tests and Account Optimizations through the year will prepare your brand to be able to pick the BFCM demand with already best performing creatives and media buying structure to not miss the hype.

Talented Team
Our team is structured in an agile way so we can adapt and adjust to your business needs fast and efficiently. Our goal is to help you launch, scale and build retention for your business.

Vice President of Growth
@Bird Buddy
I have a very high bar for what I consider to be a true performance marketer, and Flat Circle checks all of the boxes. Their team acts as a trusted advisor and trendspotter for all of their clients. Their level of communication is top-notch and so is their ability to identify bottlenecks and spot opportunities in marketing. They combine excellent pattern recognition, creativity, and science to deliver amazing results.

Eric Carlson
Co-Founder
@Sweat Pants Agency
FlatCircle passion for media ad buying and helping businesses reach their goals is exceptional. Keen eyes for details, trends, tech, and seasonality make their work as professional as possible. Only a person who truly cares about exceptional performance, will check ads several times a day for dozens of clients, and act proactively - the team at Flat Circle does that. Also, whenever you need practical advice, they will share a handful of good & bad practices with you anytime.

@Databox
As a creative strategist, I work with a lot of high-level media buyers. And I can say that the Flat Circle team is one of the best I’ve worked with. Media buying is harder post iOS updates in 2021 and you need to know what you are doing. The way they adopted the new world in the digital space is incredible. The combination of communication, efficiency, and pattern recognition is at the top level and I would highly recommend it.
Anže Markovič

Rok and his Flat Cricle team have been amazing to work with. They analysed our account in-depth and provided us with strategies for improving results and increasing revenue. 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.

Having worked with the team at Flat Circle for a number of months, the overriding impression I get is that everyone on their team truly cares about the results generated. If things aren't where they need to be, they'll do everything in their power to make sure they will be going forward!
