    LLM & AI agents in Marseille

    French Tech Aix-Marseille is gaining momentum. Local tech teams are adopting Claude API for business use cases (legal-tech, medtech, logistics) and facing the same architecture challenges everywhere: how to structure a reliable multi-agent pipeline, how to avoid the exploding bill, how to go from prototype to production.

    What we bring

    Orchestrator / sub-agent architecture
    Loops: loop-until-dry, loop-until-budget
    Agent harness: structured output + retry + abort
    Pipeline vs barrier — parallel orchestration
    Cost optimization: caching, model routing, batching
    GPT → Claude migration, existing architecture refactor
    See all patterns in detail

    Do you work in the PACA region?

    Yes, we travel to Marseille, Aix-en-Provence and throughout the PACA region. Remote sessions also work very well for code review and architecture workshops.

    Do you have experience in our sector?

    We've worked on LLM projects in legal, health, logistics and retail. Orchestration patterns are the same — domain knowledge is what you bring.
