Making your company readable by AI. Outside, and in. About
Théo and Nicole Hénusse.
HENUSSE is an independent AI consulting and engineering house, based in Le Mené, in the Côtes-d’Armor, and in Lasne, in Belgium. There are two of us, and each of us answers for their own area in their own name. Théo leads the consulting, the technical work and AI search optimisation (GEO/AEO), and he is accountable for every engagement. Nicole leads brand identity, art direction and product research. You always speak to one of us, with no intermediary.
- No commitment
- No access to your systems
- You speak to the person who will do the work
The work
Two practices, three areas, and a name behind every responsibility.
Théo Hénusse works in French and English in two practices that cover three areas:
- your company’s visibility in answers from ChatGPT, Claude and Gemini;
- building real AI tools inside companies;
- optimising workflows.
He holds one simple conviction, and it runs through the whole practice: advice is worth something only if you can verify its claims, and a method is worth something only if it still holds when the consultant is no longer in the room.
He builds the tools that support his work himself:
- a publishing and tracking engine for AI search optimisation;
- a scoping and continuity engine for the Operational Method.
These tools are not for sale. They help us deliver better and faster, and show you clearly where you stand.
Théo Hénusse
Consulting, technical work and AI search optimisation
01
Musician, then a data expert at Google
Théo Hénusse first trained as a professional musician and was awarded an ICMP scholarship endowed by Total Guitar Magazine and Gibson. He then worked on assignment at Google in London, from late 2018 to early 2019, as a data expert on a research and development project. His role was to tell the team what it was looking for, to lead data collection end to end and to assess data quality. He went on to support two more teams. The first was relaunching a stalled internal collection project, which started again with a self-service registration and collection workflow, statistics and real-time progress. The second, in Paris, handled the capture and editing of datasets. This is the same approach he applies to your business: domain first, tool second.
He has also photographed weddings on film on a semi-professional basis. This is the reason HENUSSE makes its own images rather than outsourcing them.
02
AI tools inside companies
Théo Hénusse advises companies to help them understand AI, build real tools internally and optimise their workflows. The starting point is not a demonstration: it is your rules, your context and the work that needs to flow better.
03
AI search optimisation at the frontier
HENUSSE works on AI search optimisation where the field is still being built: sources, entities, code, measurement and authority writing. We do not produce generic content on a production line. We publish verifiable pieces whose limitations remain in writing.
Nicole Hénusse
Brand identity, art direction and product research
Everything you see on our websites comes from here. Nothing is outsourced.
Her responsibility. Nicole leads brand identity, art direction, graphic design and product research, meaning what you sell, who you sell it to, and why a buyer would choose you over a competitor. On creative engagements, she is responsible for the brand end to end.
Her evidence. The three websites we present as examples, English Performance, realfrench.co and nicolehenusse.be, were designed by her and developed by Théo. This is the exact chain we sell to you, applied to our own work first. Ahead of a website build, she conducts market research, researches your defensible advantage and develops the copywriting strategy.
Her background. Nicole has drawn since childhood. She trained in a private art studio, then at a specialist art school: she is a fine artist and illustrator first. She received the Hong Kong Most Outstanding Visual Art Student Award. Design came later, at the PolyU School of Design in Hong Kong, one of the twenty-five best art and design schools in the QS world ranking by subject, 2026 edition: typography and layout, software, brand identity. There she earned her BA Design and received the Talent Development Scholarship of the Hong Kong government, culture, arts and design stream, and served as art director and executive editor of the university’s Student Press Committee. She then took that way of looking outside the studio, with an MA in Social Anthropology and Visual Ethnography at the University of Kent, and a master’s degree in political science at the Université libre de Bruxelles.
Her work. Under her maiden name, Nicole Au Yeung, she was a finalist in the COPIC AWARD for The Lovers, and shortlisted for the Hong Kong Human Rights Art Prize. Her images have been exhibited at the Goethe-Gallery in Hong Kong, at Momijiya Honkan in Kyoto and at Loft, Metro City, in Shanghai, as well as in Illustrating Anthropology, an online exhibition in the United Kingdom. She is also the author of a paper presented in the United Kingdom at the Royal Anthropological Institute Film Conference. nicolehenusse.be brings together her work as an illustrator and author. Her authority page.
Her limit. There are two of us. We take on few engagements at a time, and we say so before signing rather than after.
The structure
HENUSSE, an independent house with two voices.
HENUSSE is a surname, not an acronym. HENUSSE brings together Théo Hénusse for consulting, the method and AI search optimisation, and Nicole Hénusse for brand identity, art direction and product research. This is not an invented team: each of us answers for their own area in their own name, and nothing dissolves into an anonymous collective. Théo signs every consulting engagement.
The images are ours too. We make the photographs and films together, from shooting to editing. Nothing is outsourced, and every image is prepared for the page where it appears.
There are two of us, and that is a choice. You work directly with the people who do the work, and we deliberately limit the number of engagements so that each one receives our full attention. What we do take on, we run with our own instruments: the engine that publishes, measures and monitors this site is the one that works for our clients.
That choice does not tie you to us. Your site, your hosting, your domain name, your articles and their copyright, your infrastructure: all of it is yours, and we can hand you a clear schematic of your setup. Our own tools remain ours, but they lock you into nothing. If you stop, you keep everything, and another provider can take over. A large agency can keep its know-how in a black box. With us, what matters stays with you.
The consultancy is based as a family in Kerfiac, in Brittany, and in Lasne, in Belgium. It is grounded in written commitments, starting with its Honest Measurement Charter, meaning the public protocol that makes our measurements verifiable: fixed questions, dated readings, and failures counted alongside successes. We promise no one a citation and we inflate no figure. You judge by what is published and verifiable, not by a brochure.
HENUSSE practices
01
AI search optimisation (GEO/AEO)
We work to build your company’s presence in answers from ChatGPT, Claude and Gemini when prospective customers ask their questions, and we show you honestly where you stand.
02
The Operational Method
We install ways of working in your SME that hold up: clear scoping, a lasting company memory and work that moves forward without everything depending on you.
03
Our own websites, publicly measured
- We designed english-performance.com, we write it and we keep it running.
- We designed realfrench.co, our first proving ground, and we publicly measure what the engines answer about it.
- Nicole designed nicolehenusse.be, where she brings together her work as an illustrator and author, and Théo developed it.
Everything we offer you is applied on these three websites first, under real-world conditions. Visit them and judge for yourself.
Speak to a person, not a brand
It all starts with a 30-minute call.
Write or call directly: Théo Hénusse answers you, prepares the call and leads what follows. The call comes with no commitment, and you leave with a clear view of your situation.
