Mistral AI, the French artificial intelligence company last valued at $13.8 billion, has completed its first acquisition by purchasing Koyeb, a Paris-based startup specializing in AI app deployment infrastructure. The deal marks a significant expansion for the OpenAI competitor as it moves beyond large language model development to become a full-stack AI infrastructure provider.
Founded in 2020 by three former Scaleway employees, Koyeb developed a serverless platform that enables developers to deploy and scale applications without managing underlying infrastructure. The acquisition brings Koyeb’s 13-member team, including co-founders Yann Léger, Edouard Bonlieu, and Bastien Chatelard, into Mistral’s engineering division.
Strategic Move to Strengthen AI Infrastructure
The acquisition directly supports Mistral’s cloud computing ambitions, particularly its Mistral Compute offering announced in June 2025. According to a press release from Mistral, Koyeb’s technology will help the company deploy models on clients’ own hardware, optimize GPU utilization, and scale AI inference capabilities more effectively.
Mistral CTO and co-founder Timothée Lacroix, who will oversee the Koyeb team, stated that the startup’s product and expertise will accelerate development on the compute front and contribute to building a true AI cloud. The Koyeb platform is expected to transition into a core component of Mistral Compute over the coming months.
Building European AI Sovereignty
The acquisition aligns with broader European ambitions for AI infrastructure independence. Just days before announcing the Koyeb deal, Mistral AI revealed a $1.4 billion investment in data centers in Sweden, according to reports, responding to growing demand for alternatives to U.S.-based infrastructure.
Floriane de Maupeou, principal at Serena, the Paris-based VC firm that led Koyeb’s $7 million seed round in 2023, told TechCrunch that the combination will play a key role in building the foundations of sovereign AI infrastructure in Europe. Koyeb had raised $8.6 million in total funding since its inception.
Platform Continuity and Enterprise Focus
According to a blog post from Koyeb, the company’s existing platform will continue operating following the acquisition. However, the focus is shifting toward enterprise clients, with new users no longer able to sign up for the Starter tier.
Additionally, Koyeb’s platform previously enabled users to deploy models from Mistral and other providers. The startup had recently launched Koyeb Sandboxes, which provide isolated environments for deploying AI agents, demonstrating its evolution alongside advancing artificial intelligence infrastructure needs.
Mistral AI Growth Trajectory
The acquisition comes as Mistral AI experiences significant commercial growth. The company recently surpassed $400 million in annual recurring revenue, according to reports, driven partly by geopolitical tailwinds favoring European AI solutions and its focus on helping enterprises extract value from artificial intelligence.
Meanwhile, Mistral CEO Arthur Mensch emphasized the company’s expansion plans during Stockholm’s Techarena conference, stating that Mistral is actively hiring for infrastructure and other roles. He positioned the organization as one headquartered in Europe that conducts frontier research on the continent.
Financial terms of the Koyeb acquisition were not disclosed by Mistral AI, and authorities have not confirmed whether additional acquisitions are planned. The integration timeline and specific deployment of Koyeb’s technology within Mistral Compute remain to be detailed in the coming months as the platform transition progresses.
