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, integrated creative 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.

LGBT Switchboard

"It was a very positive experience to work with S3. They were creative, responsive and very professional. They quickly understood our sector and the brief for our campaign. They were very creative and dynamic with their input. I would recommend them highly."
