Vincent Oliveira
CEO & Co-Founder
Previously VP Growth at Birchbox France, where he scaled the A/B testing program from 8 to 200 experiments per year. Built the first version of Webyn's bandit allocation engine in a weekend to solve a specific traffic problem — and realized it worked well enough to become a product.
Sophie Marchand
CTO & Co-Founder
Former senior engineer at Criteo, where she worked on real-time bidding infrastructure processing 40 billion daily events. At Webyn, she designed the edge delivery architecture and the Bayesian inference pipeline that gives growth teams same-day test conclusions at high traffic volumes.
Adrien Fontaine
Head of Data Science
PhD in Applied Statistics from ENSAE Paris, with a thesis on sequential decision-making under uncertainty. Before Webyn, Adrien led the experimentation science team at Deezer, building the causal inference framework used across product and content decisions. He owns Webyn's Thompson Sampling implementation and the hypothesis ranking model.
