Making your company readable by AI. Outside, and in. Côtes-d’Armor · AI search and operational AI
AI search consulting in Saint-Brieuc, Lamballe and the Côtes-d’Armor: the firm lives here
HENUSSE is based in Le Mené, in the heart of the Côtes-d’Armor. Saint-Brieuc is about 45 minutes away by road, Lamballe about 30 minutes, Loudéac about 25 minutes, Dinan about an hour. The whole department fits inside the 100-kilometre radius included in our published prices. Here, we do not travel to you: we live here.
AI search, plainly said
AI search optimisation, which the industry calls GEO or AEO, means making a company citable by ChatGPT, Claude and Gemini when your future customers ask them questions, then honestly measuring what those engines answer, zeros included. We never promise a citation: our measurement charter explains how we count, at known dates, and our correlation study shows that our instrument measures what a real user sees.
Our second practice is operational AI: putting AI to work inside your business processes, the quote, the follow-up, the site report, the line-of-business software your teams already use. The integration is documented, reversible and installed in your environment, so you do not depend on us.
Why this page exists
Search and AI consultancies are almost all in Rennes, Nantes or Brest. The Côtes-d’Armor is served from afar, through Saint-Brieuc agency pages written by companies with no office and nobody there. We refuse that game in both directions: we do not pretend to be in Rennes, and we will not let it be said that nobody practises this trade from inside the department. A company in Saint-Brieuc, Lamballe, Dinan or Loudéac can be served by a firm that lives here, at the same published prices as everyone else.
How an engagement works
AI search work starts with a written Diagnostic at €1,500 excl. VAT, which you keep even if the decision is not to continue. A monthly programme can then start at €1,500 excl. VAT. For an AI integration, scoping costs €3,000 excl. VAT and an engagement starts at €12,000 excl. VAT. An on-site day costs €1,400 excl. VAT, and in the Côtes-d’Armor travel is included everywhere: the whole department is inside our radius. We work with your teams and everything is written down.
What we can show, and what we do not have yet
We are a small firm, and our most fully documented client is a company from this department: realfrench.co, the French immersion school in Saint-Gouéno, in Le Mené itself. The school belongs to the Henusse family and HENUSSE serves it; we say so, so you can judge the evidence knowing the connection. Its full diagnostic is published: reading taken from 7 to 8 August 2026, 270 engine answers read one by one, zeros included. We have no other Côtes-d’Armor reference yet and we will not invent one.

Questions we hear across the department
How much does AI search consulting with HENUSSE cost?
Everything is published in our price list, the same price for everyone, travel included. The AI Citation Diagnostic costs €1,500 excl. VAT and is deducted from the engagement that follows it within twelve months. Monthly programmes: Socle at €1,500, Autorité at €3,500, Souveraineté at €10,000 excl. VAT per month. AEO set-up alone starts at €5,000 excl. VAT.
Do I have to commit for twelve months?
Yes, for the Socle and Autorité programmes: AI citation is built over time and measured in quarterly readings, and three months do not give an honest measurement. The counterpart is written in our terms: if two successive quarterly readings show no progress after full deployment, you can leave early.
How much does integrating AI into a business cost?
Scoping costs €3,000 excl. VAT. An integration engagement starts at €12,000 excl. VAT: that is the price of one line-of-business workflow installed end to end in your environment, documented and reversible, not a subscription to a tool. Support starts at €400 excl. VAT per month and an on-site day costs €1,400 excl. VAT.
Do you cover Saint-Brieuc, Lamballe, Dinan, Guingamp?
Yes, everywhere in the Côtes-d’Armor, travel included: the whole department is inside the 100-kilometre radius around Le Mené. Remotely, we serve all of France; the readings, the client portal and the deliverables are identical. For Rennes and the Ille-et-Vilaine: our Rennes page.
