About Us


As independent consultants we are objective, realistic scientists who are passionate about what we do.

We take time to understand your strategic goals and priorities and develop a research plan with you.

We believe a sound evidence base and integrity are crucial to building credible brands and services that work.

We offer realistic solutions based on real world evidence, not what we think you want to hear, and we challenge conventional wisdom when required

We keep you regularly informed of the progress of projects and timelines and we discuss possible adaptations to objectives and timelines as soon as we are aware that they are needed 

We do not:

Cherry pick evidence

Trawl data or manipulate data 

Produce lengthy reports with no substance or actionable recommendations
