Who We Are
TBS is built by people who have spent their careers at the intersection of science, strategy, and creative. Not theorists. People who have worked on real brands, real problems, and real decisions.
Understanding how people decide – before they decide.
We use neuroscience and behavioural science to help brands predict, shape, and strengthen consumer decision-making.
The problem we are built to solve.
Brands have more data than ever. Conversion rates, heatmaps, A/B results, attribution models. And yet most cannot answer one question with confidence — why did my shopper hesitate?
That gap is where revenue is lost. It is also where TBS operates.
We combine cognitive science, real shopper observation, and digital measurement to give brands a precise, evidence-based answer to that question — and exactly what to do about it.

The foundation of our actions
