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.
