UserBoost 
Article
UserBoost was founded to bring clarity to how people make decisions and help brands connect with them at the moments that matter most.
In 2009, Adrian Grindley set out to build a digital agency with a creative heart.
By 2018, we were deep into optimisation — running our first A/B tests. Looking back, they weren’t perfect. The data was thin, the confidence shaky, and we made plenty of early mistakes. But it sparked an obsession.
Over the next several years, we ran thousands of experiments, learning what works — and more importantly, what doesn’t, especially for companies where decisions are complex.
By 2025, that experience led to a clear shift. We rebranded to UserBoost — a CRO agency focused on understanding how people make decisions, and helping brands guide them with clarity and confidence.
