Quadrangle is an award-winning consulting business based in London.

We help some of the world’s leading brands use customer knowledge and insight to improve customer – and, thereby, commercial – performance.

This draws on our unique experience across 30 years in brand marketing, strategy consulting, customer insight and data analytics.

That experience is synthesised in our approach, which we call Customer know-how.

Our approach

Customer know-how is based on a simple, brutal thought.

That if you want to improve performance, you first need to know what creates (and destroys) it in customer terms.

Then, you need to focus on this to the exclusion of all else.

That’s where the know-how is.
