Lukas Vermeer

I am an experienced experimentation practitioner. My specialty is designing and building the infrastructure and processes required to start and scale A/B testing to drive business growth. I combine industry experience in online experimentation and data science with an academic background in computing science and machine learning. For eight years, I was responsible for A/B testing at Booking.com, widely acknowledged leader in the field of online experimentation. I grew the Booking.com in-house experimentation team from four to thirty people, and became the first Director of Experimentation in the company. I help companies make A/B testing an integrated part of business processes. I advocate for accessibility of experimentation, helping people from any background (product owners, designers, developers, writers) to make the right decisions. My impact in the field of business experimentation was recognised in the Harvard Business Review story “Building a Culture of Experimentation” (March - April 2020 issue). I have co-authored multiple influential academic papers on the topic of online experimentation. I have presented at numerous conferences, including Growth Marketing Summit, CXL Live, and Google Catalyst Conference, SIGIR and KDD. Currently I am employed as Director of Experimentation at Vistaprint. I am also available as a freelance consultant to help businesses grow their experimentation culture.
