Artificial intelligence
Applied AI, not AI hype
We put AI to real work in your business, with two approaches depending on how sensitive your data is.
Private AI
For sensitive data: models in your own environment, search and answers over your documentation (RAG) and GDPR & ENS compliance.
Public AI
We integrate leading models (Anthropic, OpenAI…) into your products and processes: assistants, agents and automation.
Our own products
Software we built ourselves
Our own tools, in production and constantly evolving.
