AI is not a tool.
It’s your new operating system.

Diametral is a French consulting firm specializing in AI transformation for large enterprises. Founded in 2018 as LittleBigCode and rebranded in 2026, the firm has delivered more than 312 AI projects in production for more than 150 clients (Airbus, Carrefour, AXA, Sanofi, L'Oréal, SNCF). Its positioning rests on a simple principle: AI is not a tool you plug in, it is an operating system that redesigns critical processes.

An AI-native system is a business process entirely redesigned around artificial intelligence, not an AI tool added to an existing workflow. In practice, Diametral redesigns critical processes (supply chain, customer relations, R&D) so that AI becomes their operational engine, with continuous learning loops, built-in governance and end-to-end traceability.

Diametral delivers AI systems running in production, not PowerPoint decks or abandoned POCs. Where a traditional firm stops at recommendations, Diametral covers all four phases — Design, Build, Scale and Run — with cross-functional squads (Data Scientists, Architects, Product Managers) and commits to systematic skills transfer to in-house teams.

An AI project with Diametral takes between 4 and 12 weeks for the Design or Build phase, then extends over several months for Scale and Run. Each engagement starts with tight scoping of objectives, KPIs and budget, with a detailed proposal within 48 hours and regular demos.

Diametral works in Pharma, Defense, Insurance, Finance, Retail and Luxury. The firm draws on 8 years of operational experience in these verticals, with references such as Sanofi (drug R&D), AXA (fraud detection), L'Oréal (beauty computer vision) and Carrefour (supply chain).

A project starts with a 30-minute conversation with a Diametral expert to assess your Data maturity and scope the first use cases. Following this conversation, the firm proposes an in-depth assessment or a Design sprint, with a costed roadmap delivered within two to four weeks.
