About Us
The team that defies the ordinary.
We exist to defy the ordinary order that settles for selling campaigns and sending reports. We build a real partnership that treats your brand's growth as our own success and accounts for every penny.
Short answer: Who is Rebel Co. Group? Rebel Co. Group is a digital marketing agency in Turkey, founded 7 years ago and working from Istanbul for local and international clients. It follows a partner model instead of selling campaigns: if your brand is not growing, the agency has failed. Today it stands alongside 300+ brands across 15 industries, and everything built for you, including your site, ad accounts and data, stays in your hands.
Our Story
It started with a rebellion.
Our founder Sefa Aydın has been in this business for 12 years. In his early years in the industry he kept seeing the same picture: a campaign is sold, a report is sent, everyone moves on to the next month. Whether the brand actually grew or not is never on anyone's agenda.
Rebel Co. Group was founded 7 years ago precisely as a reaction to this order. Instead of a service list, we put a single question on the table: is your brand stronger this month than last month? To guarantee the answer is yes, we moved beyond the campaign-selling model and built the partner model. We make your goal our own goal, and if the numbers are not growing, we are the first to feel uneasy.
Today, with a remote team made up of a core management group and a network of experts, we stand alongside 300+ brands across 15 industries, working from Istanbul as a digital marketing agency in Turkey for local and international clients alike. Our scale has grown, the stubbornness we had on day one has stayed the same.
Most agencies sell services. We build result partnerships.
Our Values
Three promises that make us who we are
The promises we make to ourselves before we ever put them in a contract. On every project, for every brand, without exception.
Result Partnership
If our client is not growing, it means we have failed. We look at your revenue, not at flashy presentations: your goal is our goal, and we carry the responsibility for the outcome together.
Ownership
Everything we build belongs to you: your site, your ad accounts, your data, your content. Freedom, not dependency. Even if our paths part tomorrow, all of it stays in your hands.
Speed and Accessibility
Reachable around the clock, instant responses. Your question does not wait for office hours, and we do not keep you waiting either. You talk to a single point of contact and get your answer the same day.
Founder
Sefa Aydın
Founder, CEOI have been working to grow brands for 12 years. The picture I saw in the agency world was always the same: bright presentations, weak results. I founded Rebel Co. Group to object to this order.
Today, with our team, we look at every project with a single question: is this turning into sales? If it is not, we stop, think, and rebuild. Growing your brand is not a project for us, it is a partnership.
Alongside the agency, I teach companies and their teams to use AI on their real work: corporate AI training and one on one AI consulting on my personal site sefaaydin.com.
