TLDR: The three co-founders of French generative AI startup Mistral AI – Arthur Mensch, Timothee Lacroix, and Guillaume Lample – have become France’s first AI billionaires. This milestone follows a recent funding round that valued the company at an impressive €11.7 billion ($13.7 billion), solidifying its position as a major player in the global artificial intelligence landscape.
Paris, France – September 13, 2025 – In a significant development for the European technology sector, the three visionary co-founders of Mistral AI, a leading generative artificial intelligence firm, have officially achieved billionaire status. Arthur Mensch (33), Timothee Lacroix (34), and Guillaume Lample (34) are now recognized as France’s inaugural AI billionaires, a testament to the rapid growth and immense potential of their company.
This remarkable financial milestone comes on the heels of a substantial funding round that propelled Mistral AI’s valuation to an estimated €11.7 billion ($13.7 billion). According to the Bloomberg Billionaires Index, each founder now commands a net worth of approximately $1.1 billion. Their wealth is primarily derived from each holding at least an 8% stake in the Paris-based company, which they established in 2023.
Mistral AI is currently finalizing a Series C funding round aimed at raising €1.7 billion. This round has attracted significant new investment, notably from ASML Holding, the Dutch manufacturer of advanced chip-making equipment. Existing investors, including DST Global, Andreessen Horowitz, and French public sector investor Bpifrance, continue to support the company. CEO Arthur Mensch recently stated that the three co-founders and employees collectively retain majority shareholder control.
The company, founded in April 2023, has quickly emerged as a formidable European challenger to Silicon Valley AI giants like OpenAI and Google. Its mission, as articulated by its founders, is to democratize artificial intelligence through open-source, efficient, and innovative AI models and solutions. Mistral AI’s valuation now places it among the top-tier AI startups globally, alongside US counterparts such as Anysphere, Coreweave, and Perplexity.
The founders bring a wealth of experience from leading tech firms. Arthur Mensch, the CEO, previously spent nearly three years at Google’s AI laboratory, DeepMind. Guillaume Lample, Mistral’s scientific director, was instrumental in creating Meta’s LLaMA language model. Timothée Lacroix, the technical director, also served as a researcher at Meta. Their collective expertise and shared academic roots at École Polytechnique have been pivotal to Mistral AI’s rapid ascent.
