Lukas Vermeer

Lukas Vermeer is a specialist in online experimentation based in Delft, the Netherlands. He was responsible for A/B testing at Booking.com for eight years, growing the experimentation team from four to thirty people and becoming the company’s first Director of Experimentation. He co-wrote the paper Democratizing Online Controlled Experiments at Booking.com and has published open-source tools and simulations that explain the statistics behind A/B testing. He has since worked in product at Vista.

His talk here, given at Mind the Product Engage in Hamburg in 2018, covers the culture of experimentation at Booking.com: central tooling, hypotheses and testing the riskiest assumptions first.
