Cyllene, a French provider of sovereign hosting and managed services, announced the signing of a strategic partnership with LightOn in a release dated Sep 16, 2025. The AMF, the French markets regulator, lists the release under LightOn as inside information. The release described the alliance as meant to give mid-sized companies, large enterprises and public institutions secure, sovereign and ethical access to cutting-edge AI technologies.1^,2^,3^,4

The release said Cyllene's clients could use LightOn's generative AI directly in their sovereign environment, through a platform called IA OnDemand, and that the solution was entirely hosted in France. The release's list of features includes working with documents that mix text, images, tables and charts through retrieval-augmented generation (RAG, a technique in which a model looks up relevant documents before it answers), and a security design with access management, single sign-on and detailed auditing.5^,6^,7^,8

Olivier Morel, Cyllene's director of alliances and strategic partnerships, said the partnership gave Cyllene the chance to deliver sovereign and secure AI to French enterprises. Igor Carron, LightOn's co-founder and chief executive, said it went far beyond a commercial agreement and formed the foundation of a long-term relationship built on security, sovereignty and digital excellence.9^,10^,11^,12

The release said LightOn was founded in 2016 in Paris and that its Paradigm platform lets organizations deploy AI at scale while keeping their data confidential. Of Cyllene, the release said it had more than 400 employees across 12 agencies in France and supported over 1,500 public and private clients.13^,14
