LightOn is an AI company founded in Paris in 2016

We build the technology that lets large organisations put their own knowledge to work, safely and at the scale of the whole company. Three convictions guide us.

  • Your knowledge is yours
  • AI value comes from your data.
  • You decide who sees what.

Leading European AI

We started training AI models in Paris in 2016, years before generative AI made headlines. Where most AI companies assemble a product on top of someone else's model, we built the foundations ourselves, and we still do. That is why we became Europe's first listed generative AI company, why we are selected for European AI programmes, and why banks, industrial groups and public institutions run their data on our platform.

Europe doesn't need more companies reselling AI. It needs companies that build it. That is the role we chose ten years ago, and the one we intend to keep.
  • Founded 2016

The people leading LightOn

2026 opened a new chapter. LightOn is now led by a team that pairs ten years of AI research with decades of experience building and scaling enterprise software.

Our job is simple: turn what we know how to build into results our customers can measure.
