The human understanding agency.

Welcome to Walnut, an UNLIMITED agency.

We are more than a research agency. We are Walnut: The human understanding agency.

We help brands connect with people, by understanding people. We believe that interpreting human behaviour is as much an art as it is a science. Walnut uses market research techniques to understand what we think, how we feel and, most importantly, why.

Blending neuroscience, behavioural science and data science, we uncover the truth behind human decision making and shape the strategies that drive long term behavioural change.

We are proudly part of UNLIMITED, a fully integrated agency group with Human Understanding at the heart. Our expertise and research toolkits form a key part of the UNLIMITED Human Understanding Lab, bringing together the power of human understanding with the comms, marketing and digital transformation experts across UNLIMITED.

How we deliver human understanding.

Combining a range of research skills blended with science and behavioural heuristics, we can truly understand people, their actions and their attitudes. We deliver human understanding that allows brands to shift behaviour, launch winning products and campaigns, communicate effectively and engage with people. When a brand truly understands their audience, their customers are more likely to engage and recommend.

Our Walnut team are insight experts, specialising in:

What do we do
Brand and Comms

As humans, we lack accurate insight into our own thought processes, biases and decisions – that’s why we view understanding brands and communications as not just an art, but also a science. Beyond the capabilities of standardised testing methods, neuroscience techniques tap into a deeper level that people can’t articulate.


Innovating is crucial to the success of anything new. Walnut tests everything from products and packages to websites and branding claims; applying sensory science and behavioural economics wherever possible to provide actionable insight before, during and after a product launch.

Customer Experience

Use insight to uncover the full, extended customer journey. In the many touchpoints your audience can engage with, how is your brand performing in a competitive context? Do you know how your product or service is truly being used by people? We help brands consider every step of the customer journey experience and use human understanding to challenge existing views.
