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. LightOn went public through an IPO on the Euronext Growth market in Paris in November 2024, raising approximately EUR 12 million for its continued growth. LightOn has positioned itself as an alternative to US-based LLM API providers for European enterprises with strict data residency requirements, offering French-language performance and European regulatory compliance as primary differentiators. The company serves clients in banking, insurance, and public administration sectors where data sovereignty constraints limit the use of US-hosted AI services. LightOn competes in the European enterprise LLM market alongside Mistral AI, Aleph Alpha, and the European offerings of OpenAI, Google, and Microsoft Azure. 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's 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. DeepSeek: DeepSeek is a Chinese foundation model company founded in 2023 that develops large language models and AI systems. DeepSeek is funded by High-Flyer, a Chinese quantitative hedge fund co-founded by Liang Wenfeng, who also serves as DeepSeek's CEO. The company has not disclosed specific external funding amounts.

LightOn got there first, launching in 2016 — that's 7 years of extra runway. DeepSeek didn't arrive until 2023. In AI, that kind of head start means more training data, deeper customer relationships, and a bigger talent moat.

LightOn has about 1-50 employees; DeepSeek has about 150. A bigger team usually means more revenue or heavier VC backing, but in AI, small teams can build at massive scale.

Yes — they're direct rivals. Both LightOn and DeepSeek compete in Foundation Models, targeting many of the same buyers. If you're evaluating one, you should be looking at the other.
