Definition is the UK’s leading brand alignment consultancy

We’re born out of specialist agencies that have come together as one. Together, we’ll define what you stand for, and bring that to life in everything you say and do.

Which is easy to say, but really tricky to do. So we’ll do it together with you. And get results that actually make a difference you can measure.

We’re not jacks-of-all-trades. We’ve built our business from teams of real experts. They work together so everything you do is coherent, consistent and compelling.

That’s why the FT has named us as a Leading Management Consultant four years in a row.
