About

Gros Gradient is a micro-agency specialised in Artificial Intelligence, Data Science and Software Engineering, based in France.

The two founders design, architect and implement each project directly, with no subcontracting.

Joël : Data scientist, trained in applied mathematics and specialised in backend development and database architecture. He worked at Safran, one of the world leaders in aerospace propulsion. He contributed to the development of an AI technology that is now patented. He then joined the headquarters of AP-HP, the leading university hospital centre in Europe. There he automated data flows and the daily generation of dashboards, notably for post-Covid hospital capacity monitoring and coordination during the 2024 Olympics. This experience enables him to design reliable systems for handling sensitive data, warehousing information and producing analyses or visualisations that business teams can use.

Ninoh : Engineer in Natural Language Processing and AI. He designs, trains, hosts and deploys open-source French-language models as well as the tools that use them. His expertise also covers infrastructure and cloud. He has developed and deployed NLP models for professional platforms, from data preparation to production integration. He contributed to idealCO by integrating language processing micro-services. He also worked on cedille.ai, the largest open-source French-language model in 2022. This expertise enables him to design LLM-based systems that are truly usable: intelligent search in your documents, internal assistants and text analysis tools deployed locally or on sovereign infrastructures in the European Union.

Together, Joël and Ninoh came 2nd in an international NLP challenge organised by Orange Silicon Valley in 2023. This challenge led to the publication of a research paper. Since then, they have joined forces to offer personalised services to companies.

Who we work with

We work with SMEs, associations and companies that do not have a dedicated technical department, as well as with larger structures that need targeted support.

Typical projects:

• semantic search engines and internal AI assistants (NLP, RAG, LLM);
• monitoring, data pipelines, automated report production, visualisations (dashboards);
• websites and applications, from simple showcases to custom internal tools.

Some of these projects are visible in our interactive 3D portfolio.
