Mistral AI
The Paris model lab founded in April 2023 by three French researchers from Google DeepMind and Meta, which made its name by releasing small, efficient open-weight models under the permissive Apache 2.0 licence (Mistral 7B, September 2023; Mixtral, December 2023) and then built a business selling commercial models, an assistant (Le Chat), on-premises deployments and, from 2025, its own compute to European companies and governments that want an alternative to American and Chinese AI. It is Europe's best-funded independent lab: €1.7bn at €11.7bn led by ASML (September 2025) and €3bn at more than €21bn led by Samsung (September 2026) (companies). Revenue is small next to the US frontier labs: a run-rate above $400m in February 2026, with a target above $1bn by the end of 2026 (company claims, reported). Its controversies are about what "open" and "sovereign" mean: its turn to closed flagship models in 2024, its lobbying on the EU AI Act, and a small Microsoft investment that critics saw as a contradiction.
