History
Mistral AI was founded by three AI researchers who met at École Polytechnique: Arthur Mensch, former researcher at Google DeepMind; Guillaume Lample, and Timothée Lacroix, both previously with Meta AI.[7] Their goal was to create efficient, open-weight AI models to democratize access to AI technology and challenge the dominance of proprietary systems.[8]
In June 2023, Mistral AI raised €105 million from investors, including Lightspeed Venture Partners, Eric Schmidt, and Xavier Niel, valuing the company at €240 million.[9] By December 2023, a second funding round of €385 million, led by Andreessen Horowitz, BNP Paribas, and Salesforce, increased its valuation to €2 billion.[10][11] In June 2024, a €600 million round, led by General Catalyst, raised the valuation to €5.8 billion, making Mistral AI a leading AI company outside the San Francisco Bay Area.[12][13]
On 26 February 2024, Mistral AI partnered with Microsoft to integrate its models into Microsoft Azure, expanding its global reach.[14] By 2025, the company employed 150 people and continued to develop new models and services.[1]
