About

Arthur Mensch co-founded Mistral AI in May 2023 and built Europe's flagship AI lab, whose September 2025 Series C — €1.7 billion led by ASML — valued it at €11.7 billion (~$13.7B).

He founded Mistral with Guillaume Lample and Timothée Lacroix, both then at Meta AI, and has become Europe's leading voice for open-weight models and AI sovereignty. TIME named him to its 100 innovators list in 2024; France knighted him in 2025.
