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). A product of the French elite-math pipeline (Polytechnique, Télécom Paris, the MVA master at ENS Paris-Saclay, a Paris-Saclay PhD in machine learning for brain imaging), he was a research scientist at DeepMind in Paris, where he co-led the Chinchilla paper that reset the field's scaling laws and contributed to Flamingo. 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.
