Enterprise AI search platform that makes company knowledge agent-readable
LightOn is a Paris AI company founded in 2016 that builds an enterprise AI search platform: it turns an organisation's document estate into a governed, machine-readable source of truth and powers use cases such as search, comparison, extraction, monitoring, and scoring on top of it. It trains its own open-weight models for document understanding and retrieval and describes itself as Europe's first listed generative AI company (Euronext Growth Paris: ALTAI). In September 2026 it renewed bond financing of up to EUR 4M with existing partners, extending its cash runway to September 2027.
