The eight-year journey for French startup LightOn since its inception in 2016 has been a roller-coaster ride. Within four years of its foundation, the GenAI specialist pioneered in the field of Large Language Models, or LLM, with cutting-edge models and products.

The company’s foray into the global technological market was led with the ambition to push the boundaries of extreme-scale AI.

By 2022, recognizing the need for a comprehensive ecosystem and tailored tools for effective AI deployment, LightOn introduced Paradigm. This platform facilitates the deployment of generative AI for top-tier companies, addressing their specific requirements.

In October this year, LightOn reported a 15 per cent rise in first-half revenue compared with the same period the previous year.

The French AI company made its stock market debut as Europe's first listed GenAI company on the Euronext Growth exchange in December 2024. It develops large language models, or LLM, for customers with strict security requirements such as Safran and the French Space Command. In its efforts to explore new geographies, LightOn, Edarat Group, and NVIDIA recently collaborated with Orange Business to launch Live Intelligence in the Gulf region.

Strategic Partnership

In July this year, the startup announced a partnership with ArianeGroup's subsidiary Sodern, which develops and produces critical components for the French nuclear deterrent force and intercontinental ballistic missiles.

In enterprise search, LightOn offers sovereign and multimodal document search. The LightOn Enterprise Search is the safest and most performant enterprise search engine on the market, delivering instant access to all your data in your on-premises environment or sovereign cloud.

It allows search across all content, text, images, diagrams, office formats (Word, Excel, PowerPoint, PDF, etc.), with in-house optimized embeddings.

Besides, there is an option of synchronization with the systems SharePoint, ServiceNow, Microsoft Teams, Confluence, and fine-grained access rights management (ACL/IAM).

Alfred Model and Paradigm Platform

The Alfred model and the Paradigm platform provide large corporations, government, and public institutions with tailored, efficient generative AI solutions that can be easily integrated into their infrastructure, ensuring data confidentiality.

With a tagline “Gen AI for Enterprise”, LightOn thrives with a mission to “Deliver Amazing GenAI to Enterprise” and a vision of “Generative AI that fades into the background, empowering seamless usage and unlocking enterprise productivity.”

By 2022, recognizing the need for a comprehensive ecosystem and tailored tools for effective AI deployment, LightOn introduced Paradigm. This platform facilitates the deployment of generative AI for top-tier companies, addressing their specific requirements.

Intuitive User

LightOn is helping businesses with Custom Digital Assistants as Paradigm’s AI agents are tailored assistants designed for every department.

The Private Chat by LightOn is a secure and powerful AI assistant. It enhances daily tasks across all departments.

With agentic and multi-assistant capabilities, users can let the system select the most appropriate specialized assistant or manually choose the one that best fits.

A simple and intuitive user experience is the top priority for LightOn. The private chat is designed for seamless adoption so that everyone in the company hierarchy can use it effortlessly.

As businesses have unique workflows that require tailored automation, private chat allows for API Integration, which can enhance internal tools with generative AI through Paradigm’s comprehensive API.

Similarly, with the database and external tool integration, there is an option to query the company’s data sources directly from the chat.

The custom tools help build deterministic use cases to automate repetitive and complex tasks.

GenAI Enterprise

LightOn has brought innovation in integrating Gen AI with professional services support.

It offers handholding in integrating Gen AI enterprise with the help of its expert team, which is dedicated to ensuring that a business can leverage the full potential of the technology to enhance productivity.

There is an option to create Custom AI with LightOn experts for custom business case development, thematic workshops and expert training, infrastructure management support, and personalized model customization.

Besides striking a balance in its management and board of directors, LightOn has formed committees including audit and risk committee, and nominations and remuneration committee.

One of LightOn's major strengths lies in its diversity. With an international team of 40, the company welcomes talent from more than 10 different nationalities.

Since 2020, LightOn has pioneered in the field of Large Language Models, with cutting-edge models and products.
