What Makes Us Different?

What makes Serotonin different is our ability to combine creative thinking with commercial focus. We’re not just media buyers or content creators—we’re growth partners. Every campaign we run starts with strategy, backed by data, and is built to deliver real business impact.

What sets us apart is pace and clarity. We work fast, think clearly, and cut straight to what’s going to drive revenue. Our clients trust us because we treat their budgets like our own and hold ourselves accountable to the results. No bloated teams, no hiding behind jargon—just smart, senior marketers who get it done.

We’re proud to be based in Manchester, but we operate globally—helping brands grow across the UK, Europe, and the US. Whether you’re scaling an eCommerce brand or launching something new, we bring the thinking, systems and creative needed to make it work.

At Serotonin, we don’t just run ads—we unlock growth.
