Almia is the proprietary generative artificial intelligence platform developed in-house by AG2R LA MONDIALE, a major joint and mutual insurance group in France (15 million policyholders, 500,000 client companies). Launched among about a hundred "Champions IA" in April 2024, then opened to all employees in January 2025, the platform reached a remarkable adoption rate by the end of 2025: 7,000 users out of 8,300 employees, with roughly 1,300 AI assistants created by the users themselves.

The platform is built around four complementary pillars. Almia Bot offers a secure chatbot that lets users query several LLMs via RAG, with an internal marketplace of assistants rated by users. Almia Apps industrializes the best-performing assistants into dedicated business applications (analysis of customer verbatims, marketing campaign generation, document processing). Almia Dev exposes generative AI APIs for developers and actuaries. More recently, Almia Agents deploys business AI agents integrated into the value chain.

The infrastructure runs on S3NS, a Thales-Google Cloud joint venture hosted in France, qualified SecNumCloud 3.2 by ANSSI in December 2025. Data protection relies on vectorization: internal documents are broken down into unusable vectors before being sent to the LLMs, with the original texts remaining stored locally. The approach is multi-LLM and agnostic, allowing the best model to be chosen for each use case.

The deployment strategy relies on a network of Champions IA drawn from the business units, each training their colleagues. Three mandatory training sessions (AI literacy, security, ethics) are required to access the platform. This peer-based approach, supported by the WEnvision consulting firm, enabled rapid and controlled adoption.

A formalized AI governance body brings together the AI director, the DPO, the CISO, and CSR compliance to review all AI experiments and ensure compliance with the European AI Act. The principle is clear: AI assists employees without ever replacing human expertise.

Almia is part of a six-year, €629 million IT transformation program. The project earned Pascal Martinez, IT and Digital director, the title of IT Strategist 2025. With the arrival of new CEO Fabrice Heyries at the end of 2025 and his "Esprit de conquête" (spirit of conquest) strategy, AI is now a strategic lever for differentiation for the group.
