Sébastien Beyet worked as a senior strategy consultant at Ares & Company. In 2016 he co-founded Agicap in Lyon with Clément Mauguet and Lucas Bertola, to give small companies a live view of their cash instead of an out-of-date spreadsheet.
In 2019 Agicap raised €2.4 million from BlackFin Capital and Kima Ventures. In 2020 Partech invested €15 million, and the company opened in Germany, Spain, Italy and the Netherlands.
In 2021 Greenoaks Capital invested about €82 million, or $100 million. In 2022 Agicap grew 100%, planned to hire 600 people and joined the French Tech 120, a place it kept in 2023.
In November 2024 it raised a Series C of about €45 million with AXA Venture Partners and Accel among the investors, to move into mid-sized companies across Europe.
