Guilhem Bellion is a co-founder of Spendesk. He started the company with Rodolphe Ardant, who became chief executive, and Jordane Giuly, who later left.
Spendesk was incorporated on 1 August 2016 inside eFounders. Between 2018 and 2019 the team grew from 20 to 120 people. By 2020 the product had 40,000 users, although the year brought a net loss of about €18.1 million on revenue of €8.2 million.
General Atlantic led a €100 million round in July 2021, and another €100 million followed in January 2022. That made Spendesk the 26th French unicorn.
In September 2024 the company cut about 150 jobs after heavy losses. In March 2025 it had its first profitable month, and annual recurring revenue reached €52 million in the first quarter.
