Founded

Mistral AI is a French artificial intelligence company founded in Paris in 2023 by Arthur Mensch, Guillaume Lample and Timothee Lacroix, three researchers who previously worked at Google DeepMind and Meta. It trains and sells large language models, releasing some model weights openly under permissive licences and others as commercial models available through its own API and through cloud marketplaces. Its products include the Le Chat assistant, coding and document processing models, and a deployment offer aimed at enterprises and governments that want models run on their own infrastructure inside Europe. In September 2025 the company raised 1.7 billion euros in a Series C round at a post money valuation of 11.7 billion euros.

Mistral AI files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Mistral AI: Mistral AI raises 1.7B euros to accelerate technological progress with AI, Orrick: Orrick Advises Mistral AI in its 1.7B euro Series C Funding Round and TechCrunch: What is Mistral AI, everything to know about the OpenAI competitor. The ownership figures below come from the holders' filings instead, and are sourced row by row.

The disclosed stakes

One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.

Where each figure comes from

A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

What this page is not

It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Mistral AI where a holder stated one, and are missing where no holder did.
