About Serotonin
Serotonin is a Manchester-based performance marketing agency founded in 2019 by Dom Carter and Clair Heaviside, specializing in paid media management across Google Ads, Meta, TikTok, and Amazon, alongside brand strategy, web design, and eCommerce marketing. The firm emphasizes clarity, commercial focus, and fast execution across the marketing funnel, serving clients across the UK, Europe, and US. With a 5.0 Clutch rating across nine verified reviews, they operate with a very low hourly rate that reflects their early growth-stage positioning.
Who Serotonin Is Best For
Serotonin is a strong fit for eCommerce and consumer brands in beauty, sports, and construction that want a commercially focused paid media team that moves quickly and prioritizes measurable outcomes. Their very accessible pricing makes them particularly attractive for growing brands with limited marketing budgets. Companies looking to test new channels like TikTok Ads alongside established Google and Meta campaigns get good value.

Used these guys for the last 12 months and we have increased our revenue by over 85%, launched Google ads very successfully and improved our ROAS by a great margin. Thanks!
A refreshingly honest and straight-talking agency. Just got off a call with Dom, he was incredibly helpful, friendly, and full of useful advice. Although we’re not in a position to go ahead with the full service right now, Dom still took the time to point me in the right direction and share some genuinely valuable insights. Really appreciated the honesty and support. Thank you Dom!
