Guillaume Aubin co-founded Alven over two decades ago and has remained Managing Partner throughout, giving him unusually long-tenured continuity as both firm builder and active investor at the same platform rather than moving between funds or into operating roles. He has built a reputation as a repeat backer of category-defining French and European consumer internet companies from very early stages, including early investments in success stories such as Qonto and Algolia, positioning him as a long-term champion of French-founded global SaaS and fintech winners.
