Summary
👤
Senior🎓
Top SchoolCharles Ruelle is a seasoned technology and product leader with 18 years of experience building digital platforms, leading innovation programs and founding mission-driven startups. As Founder & CEO of Sezame he is democratizing home ownership in France through lease-to-own solutions and tailored customer journeys, drawing on prior leadership of global innovation at Euler Hermes and large-scale social media operations at Havas. He combines public-sector tech experience—having launched France’s data.gouv.fr as Etalab’s first CTO—with entrepreneurial exits in consumer platforms and ecological search, showing fluency across government, corporate and startup ecosystems. Charles is also an active investor with stakes in multiple European startups, bringing operator experience to board-level decisions. His profile blends product-led growth, platform and API strategy, and lean innovation methods—skills he has repeatedly used to scale teams and launches across markets. Less obvious: he pairs this strategic breadth with hands-on technical roots (CTO roles and R&D experience), enabling him to move quickly from concept to deployed services.
