Founded: April 2023
Headquarters: Paris, France
Founders: Arthur Mensch, Guillaume Lample, Timothee Lacroix
Pushes against: US closed-model labs and Chinese open-weights labs; positions as a non-US, non-Chinese alternative.
Now: Raised EUR 3B at EUR 21B+ on 2026-09-08, led by Samsung; July 2026 Microsoft compute deal reported. Frontier-gap catch-up model family due to open to partners in early access in July (CEO, reported).
