CRAP Talks

Welcome To CRAP Talks. London’s biggest Conversion Rate Optimisation, Analytics and Product meetup. No other meetup or conference brings together so many disciplines into one room – and if they do, they don’t do it with the same quality of speakers. Don’t let the CRAP acronym fool you. In reality we don’t just cover CRO, data analysis and product management, we also cover data science, marketing, User Experience (UX) and a whole bunch more, see our videos below for proof.

So what’s our secret? It’s simple really. We grind away to find the needles in the haystacks. The people who are still down in the trenches quietly innovating and doing impressive work. Those are the people we want to hear from. They may not be seasoned speakers, they may never have even spoken in public before, but we don’t care, they are the types of speakers we have speaking at our events and we work damn hard to find them!

  • Part 1: A better way to think about “Minimum Detectable Effect - The Minimum Detectable Effect or MDE has always baffled me, and not because it’s a difficult concept to understand but rather because most people working in the field of experimentation have been using it counter-intuitively for so long. For the record, I don’t think any of what I’m about to write is groundbreaking, but having […]

  • Choosing your battles at work - It’s nice when everyone is in agreement about something. It’s even nicer when that agreement is around your way of thinking. But let’s face it, if everyone agreed with each other all the time, the world would be a pretty boring place. Our uniqueness, whilst making us special, can often lead to conflict at work […]
