Building an A/B Testing Culture

The challenge

Etos had limited in-house AB testing experience before our partnership began. Their approach to experimentation was minimal, which slowed digital optimization and hindered continuous growth. Without structured testing processes, they weren't systematically learning from user behavior or making data-driven improvements to their health and beauty webshop.

The solution

For more than seven years, we became their trusted experiment-led growth partner, designing, building, and launching more than 600 AB tests together. This deep collaboration unlocked ongoing digital improvements, higher conversion rates every year, and embedded a data-driven culture across their teams. Our hands-on CRO expertise transformed Etos' approach to digital optimization, making AB testing part of their DNA.

THE IMPACT WE MADE

Our partnership empowered Etos to consistently turn insights into action, driving measurable uplifts in conversion rates and digital performance year over year. Today, A/B testing is at the core of Etos' online strategy, enabling smarter decisions with proven business impact.
