French AI company Mistral AI announced its first acquisition today. The company will purchase serverless cloud provider Koyeb, also from France, aiming to enhance its compute infrastructure and support its growing portfolio of AI services.
Mistral AI has entered into a definitive agreement to acquire Koyeb, a Paris-based startup providing high-performance serverless infrastructure. The deal brings together 13 employees, including Koyeb’s three co-founders, who will join Mistral’s engineering team in March 2026.
Mistral is accelerating its infrastructure investments along with the acquisition. The company is targeting 1 billion dollars (and presumably 0.85 times that in euros) in revenue for 2026, which would mean a sharp increase from its current run rate of 400 million dollars.
Serverless infrastructure for AI workloads
Koyeb provides a serverless platform designed to run and scale AI applications without requiring developers to manage the underlying infrastructure. The platform combines serverless efficiency with unified capabilities for running inference, executing AI-generated code securely, and powering AI-native applications such as APIs, MCP servers, and web services.
According to Mistral’s announcement, Koyeb’s product and expertise will support existing environments, including sandboxes and MCP servers. It will also improve Mistral’s ability to deploy models on-premises, optimize GPU usage, and help inference teams scale AI workloads more efficiently.
“Koyeb’s product and expertise will accelerate our development on the Compute front, and contribute to building a true AI Cloud,” said Timothée Lacroix, Mistral AI’s co-founder and CTO.
European AI infrastructure expansion
The acquisition points to vertical integration becoming a key target for Mistral. The company is building its own AI infrastructure, including data centers in Sweden, as it competes with U.S. giants like OpenAI and Anthropic. By owning more of its technology stack, Mistral aims to reduce dependencies on third-party cloud providers. This is similar to what its American rivals are attempting to accomplish, including with OpenAI’s joint Stargate effort with Oracle and SoftBank, a project worth hundreds of billions of dollars.
Yann Leger, Koyeb CEO and co-founder, said: “AI has redefined cloud infrastructure. We started Koyeb to build the best serverless cloud platform to run and scale intensive applications globally. By joining Mistral AI, we plan to double down on that mission with the support and resources of a global AI leader.”
It’s likely the acquisition will merely be the first of many. Mistral’s current status as an AI lab is relatively difficult to expand on organically, especially for short-term infrastructure needs.
