About S3 Advertising

A proud, Welsh agency with a bold, worldwide vision: welcome to S3, The Drum Network’s Advertising Agency of the Year 2016.

Our mission? To disrupt your potential audience and get them to pay attention to you. How do we do this? Between us we have over 300 years’ industry experience, and when combined with unrivalled audience insight platforms and a large dash of personality, talent and flair, we get you results.

Our motto – People First – is the driving force behind everything we do as an agency. We are people’s people, which is why we’ll always choose face-to-face meetings with our clients over impersonal email conversations. Something that helps explain why we’ve been voted #1 for Client Satisfaction at The Drum Digital Census – three years in a row.

With our Cardiff office – The Lion’s Den – voted the UK’s second coolest, we now have our sights firmly set on London, a new office in the heart of the city demonstrating our intent to continue to stand up to the industry’s heavyweights.

But we’ll never let our own achievements get in the way of our commitment to put the needs, satisfaction and ROI of our clients before everything else. It’s why some of the industry’s most exciting brands are choosing to work with us and why, after getting to know us, you’ll want to do the same.
