About Xavier

20 years of career with a dual role as entrepreneur & tech. A successful exit for OfficeRiders and many companies supported at key moments in their development.

Today, I deploy and manage complex agentic AI systems, integrating cognitive memories and multi-agent orchestration to create autonomous infrastructures for business strategy, while ensuring profitable and controlled scaling.

My methodology relies on managing three types of critical knowledge:
  • Strategic Knowledge (The Human Brain): I integrate your vision, brand tone, and business objectives as the system's "Constitution." The AI acts under your guidance, respecting your company's DNA.
  • Cold Knowledge (The Technical Library): I deploy "Scout" agents dedicated to continuous monitoring and analysis (competitors, documentation, platforms, etc.). Your knowledge base updates itself, without human intervention.
  • Hot Knowledge (Contextual Memory): Thanks to cognitive memory systems, my agents learn from every interaction. They memorize customer preferences and field feedback in real-time for surgical precision with each iteration.
All of this is built on a robust and sovereign infrastructure (open source) that optimizes token usage by intelligently enriching the context.

I guarantee maximum accuracy without overconsuming your resources, by choosing the right model for the right cost for each task.

I intervene in short, intensive formats to move from diagnosis to operational infrastructure. An optional quarterly audit then ensures usage monitoring, challenges inference costs, and evolves your system's memory.
