Enterprise generative AI platform with grounded retrieval, document parsing, structured extraction, and deployment from EU cloud to fully on-premise.

French enterprise AI platform, publicly listed in Paris, with sovereign EU deployment.

LightOn is a French enterprise AI platform and Europe's first publicly listed pure-play generative AI company, trading on Euronext Growth Paris since November 2024. Where consumer chatbots stop, LightOn starts: grounded retrieval with citations, document parsing that turns scans and handwriting into structured Markdown, and schema-based extraction, all built for regulated organizations.

Deployment flexibility is the differentiator: run it as SaaS on EU sovereign hosting, in a dedicated cloud, inside your VPC, or fully on-premise where no token ever leaves your infrastructure. Enterprise controls include SSO, RBAC, SCIM provisioning, workspace ACLs for agents, and audit logs, with SecNumCloud compliance available for the most sensitive French deployments.

Key features:

  • Grounded retrieval with citations, combining dense and sparse search
  • Document parsing for scans, tables, handwriting, and complex layouts
  • Structured extraction driven by JSON schemas with async webhooks
  • Deployment anywhere from EU SaaS to air-gapped on-premise
  • Enterprise security with SSO, RBAC, SCIM, and audit logs
  • Free starter tier with pure usage-based pricing, no commitment
  • GDPR, SOC 2, and AI Act-ready posture stated across the platform

LightOn SA is headquartered in Paris, France, founded in 2016, and serves Safran, Région Île-de-France, and the French tax authority among others, with partnerships including Orange Business and HPE.

Ideal for European enterprises and public bodies that want ChatGPT-class capability on infrastructure their regulators will accept.
