Quadrangle Research Group

We are a customer consultancy.
We help brands understand, and play into what matters to customers.

Quadrangle is an award-winning customer consultancy based in London. We help ambitious brands improve customer and commercial performance. Our role is to ensure brand decision-making, delivery and measures are driven by a deep, honest understanding of what matters to customers.

We start from the view that customers create the value in brands; and that digital has further heightened the importance of this truth.

The work we do draws on Quadrangle's unique, 30-year experience across research and insight, brand marketing, analytics and strategy. It is underpinned by the attitude at the very heart of our business: Entrepreneurial imagination.

Our work centres around creating that understanding for brands, in ways that enable decision makers to:

1. Identify and prioritise what makes the difference for their customers. For this, we draw on all five sources of insight (i.e. asking, listening, collecting, observing and connecting), infilling any gaps with new insight that we create ourselves.

2. Ensure brand strategy, delivery and measures are fully aligned with what matters to customers. We do this for the brand as a whole, or in a specific area, such as Customer Experience. Here, knowing that what gets measured gets managed, we have a particular focus on customer metrics, feedback systems, and tracking programmes.
