Who says small can’t do what big can?
Buck up your ideas, mun!

This is where the little bite big.

What makes us different? We exist to help the unlikely and underestimated in their pursuit to become the overachievers they damn right deserve to be.

An independent, creative advertising agency based in the heart of Cardiff, we produce consumer-facing campaigns for those who aren’t (yet) market leaders.

This agency doesn’t ego pander and it certainly doesn’t think small, everything we do rewards ambition using S|3: strengths, skills and success.






We were an early bird to Tok Tok ads - here's what we learnt and how it performed

Us at S3 advertising agency pride ourselves on being one of the first to try, understand and learn from new things in the industry. It’s part of our DNA; from being the first to re-imagine Cardiff’s Alliance Ring as a one-of-a-kind billboard, to the Team S3 monthly ritual of trying new skills, together, during our monthly personal development afternoon. So, when TikTok began to take off in 2019, S3’s digital advertising team were hot on the case investigating how we could innovate.
