Estuaire AI Practice

Estuaire AI Practice is a six-person consultancy in Nantes that focuses on the early, inexpensive part of AI Act preparation: working out which of a company's systems are in scope, how they should be classified, and what evidence is missing before anyone commits to a full compliance programme. Its readiness assessments are designed to fit under a small budget and take two to three weeks, delivered over video calls and shared documents. Roughly half of the firm's clients build clinical decision support or patient-facing software, where the AI Act obligations sit on top of medical device regulation, and the team is used to mapping the two against each other. The rest are general software companies that want a second opinion before signing up a larger firm. Estuaire also runs bias audits of scoring and triage models using the client's own test data, reporting against the NIST AI RMF measure function and the AI Act's data governance article. The founders write up findings in plain French or English and avoid producing documents the client will never read. There is no office; all staff work remotely from western France. The firm does not draft legal opinions, does not implement management systems, and is not a notified body.
