The method behind the madness

Methodologies used for this project

A/B Testing

"Build, Measure, Learn" for continuous optimisation

By creating a backlog of hypotheses, we've set ourselves into a continuous cycle of A/B testing that drives growth and innovation. Each hypothesis is backed by research or behavioral economics, and then prioritised for testing.
