About
Guilhem Bellion is the engineer of the trio that built Spendesk into the first profitable spend management platform in Europe. He co-founded it in Paris in 2016 with Rodolphe Ardant and Jordane Giuly inside the eFounders startup studio, where he was already a software engineer, and built the product that now carries more than 200,000 business users and handled some €20 billion of company spend in 2024. Spendesk became a French unicorn in January 2022 when Tiger Global led a $114 million Series C extension at a $1.14 billion valuation, and it broke even in the first quarter of 2025 — a milestone almost no European fintech of its generation has reached. He has stayed with the company through every stage of that climb.
