Lionel Roux

CEO at Wimi

An entrepreneur committed to European digital sovereignty, Lionel Roux has led Wimi since its creation with a clear vision: to offer companies an effective French alternative to American collaboration giants.

An engineer by training with 20 years of experience in business software, Lionel built Wimi on a strong conviction: European companies should not have to choose between performance and sovereignty. Under his leadership, Wimi is in the process of qualifying SecNumCloud by Q1 2026.

An active defender of the trusted cloud, he regularly intervenes on digital sovereignty issues with French and European institutions. Its mission: to demonstrate that an independent European tech can compete with GAFAM while guaranteeing total legal protection of data.

Lionel leads a team of 20 passionate experts who share his vision of a strong and independent European digital economy. Under his leadership, Wimi has successfully completed more than 300 migrations from American solutions, allowing its customers to save an average of 40% on their costs while regaining control of their data.
