Mistral AI is a Paris-based AI company founded in 2023 by former DeepMind and Meta researchers. In under three years, they’ve reached a $6 billion valuation, hit 1 million Le Chat downloads in two weeks, and built models that compete with GPT-5 and Claude at a fraction of the cost.
They’re the only major AI lab based in Europe, which matters for GDPR compliance and data sovereignty.
