Research projects have a tendency to become over-engineered, huge, expensive and in flexible mega projects that take forever to complete. We want to change that and uncover relevant insights, with the right target fast. Roughly right is better than precisely wrong.

No endless discussion, long lead times, huge projects. We like to get started, iterate and learn.

Behavioural Science x Lean Start-up

Imagine Behavioural Science (study of understanding human behaviour) and Lean Start-up methodology (validating ideas fast) had a baby. That’s us.


We love diving into the context of different countries. Have loads of experience working across borders and a global partner network.

Positive impact

We focus on positive impact projects only. The bright minds of this world should focus on solving world's biggest problems over maximizing shareholder value.
