Frequent questions
Do you only work in the Nantes region?+
No — most engagements are remote or on-site occasionally. Nantes is the HQ; the whole of France (and French-speaking markets) is the field.
Are your rates negotiable?+
Yes, based on volume and scope. Published grids are indicative. AI onboarding tiers are designed to be deductible from the next phase if you continue.
What's the difference with a large IT firm?+
Capped portfolio, senior execution without resale, single point of contact. No opaque day-rate billing: scope and deliverables are locked upfront.
Do you sign an NDA?+
Always — either yours, or MAG&Cie's standard NDA. Multi-party NDAs supported for due diligence.
