Mistral Raises €3bn Series D at Over €21bn Valuation, Led by Samsung

Founded in 2023 by Arthur Mensch, Guillaume Lample and Timothée Lacroix, Mistral develops open-weight AI models along with the infrastructure and products used to deploy them for businesses and public-sector organisations. The company positions its technology around demand from organisations seeking more control over how AI systems are run, including where data is stored, how models are customised and which infrastructure is used. Its platform is designed to let customers operate AI systems without depending on a single technology provider and to keep sensitive data within their own environments.

Mistral currently operates across 20 countries and says it supports more than 125 enterprise customers, including Airbus, ASML and HSBC, across sectors such as finance, manufacturing, defence and energy.

EU-Startups quoted co-founder and chief executive Arthur Mensch as saying that who controls intelligence, and who can adapt it to their own needs, matters as much as how powerful it is, adding that this is why Mistral was built on open-weight models from the outset and has since expanded into infrastructure, products and deployment.
