LightOn: LightOn develops large language model APIs and enterprise AI products for European organisations, building foundation model capabilities with a focus on European data sovereignty, multilingual performance, and on-premises deployment options that address GDPR compliance requirements for French and European corporate clients. The Paris company offers the Alfred enterprise AI assistant and LLM API infrastructure designed for deployment within private European cloud environments.\n\nThe company raised approximately $60 million including a Series B round from investors including BpiFrance and other European technology investors.

The European sovereign AI market has attracted growing policy attention and funding as the EU AI Act and data localisation regulations create demand for AI infrastructure that can operate entirely within European jurisdiction. LightOn early focus on optical computing for AI workloads has evolved into a software-first model API and enterprise application strategy, reflecting the commercial viability challenges of novel hardware approaches to AI computation.
