Stuart Clare is the senior manager of digital trading, optimization, and personalization at the AA — one of the UK's most iconic brands. he's spent four years building an experimentation program from scratch, across five different product journeys, with a team of four.

calm under pressure, process-obsessed, and still checking dashboards first thing every morning, just like he did when he was A/B testing email subject lines.


it's about:

→ how to build an experimentation program from nothing — and get leadership to fund it

→ the loss prevention argument that makes any business case impossible to ignore

→ why a 25% win rate is healthy (and why chasing a higher one is actually dangerous)

→ app testing: why it's a completely different beast and what nobody tells you about it

→ the 1 thing that has stayed consistent across every company, every product, every journey
