Why We Built Webyn
Vincent Oliveira spent four years running growth at a Paris-based e-commerce company with 800,000 monthly visitors. The team had a respectable A/B testing program: 3–5 tests per month, a dedicated analyst, and a standard testing tool that everyone in the industry used.
The problem was the wait. Each test needed 3–4 weeks to reach statistical significance. By the time a winner was declared, the original hypothesis was often stale — the product had changed, the campaign had ended, or the engineering team had moved on. The team was running 40 tests per year instead of 200.
Vincent left in 2022 to build what he described as "a testing platform that doesn't make you wait for the numbers to cooperate." He recruited two former colleagues with backgrounds in Bayesian statistics and frontend infrastructure, and Webyn shipped its first customer deployment in early 2023.
Today Webyn processes experiments for growth teams across Europe. Sharpstone Capital led the €2.5M Seed Round in 2024 to accelerate product development and expand the team.
