Mistral AI acquires French code reliability startup SkipLabs

Mistral AI confirmed on November 5 that it bought SkipLabs, a Paris and London company founded in 2022 by Julien Verlaguet, a former Meta engineer who worked on the Hack language. Terms were not disclosed. Six SkipLabs engineers and scientists will join a new internal group called Language, which sits under Guillaume Lample, Mistral's chief scientist and co-founder. The group will build tools that help coding models write more reliable code and that feed into training and evaluation.

The purchase is Mistral's fifth acquisition of 2026, after Koyeb, Emmi AI, Pimento and New Material. Those deals move the company beyond model releases into cloud infrastructure, industrial simulation, advertising tools and code verification. Coding assistants from OpenAI and Anthropic set the competitive bar for this kind of product.

For founders, the signal is that model labs now buy narrow developer tooling to improve their own models, not only to ship new products. A team with verification or code-reliability expertise can attract a strategic buyer when its work plugs into a lab's training loop.
