A team of founders
No juniors learning on your budget. The people who design your strategy are the same ones who execute it — three founders, three areas of expertise, one direction.
Optimized to be cited in
What follows is written and checked by people.
Diagnosis, content, technical work, reporting: the same small team follows every step, from the first audit to the monthly report. No anonymous subcontracting, no unreviewed generated content.



LUWIZ was born from a conviction shared by three founders: SEO and AI visibility are the same problem seen from two angles. Rather than assembling a team of interchangeable profiles, we brought together three complementary areas of expertise — GEO strategy, technical SEO and content — all pulling in the same direction.
Why a team of founders changes everything
In many agencies, the people who sell you the strategy aren't the ones who execute it. The salesperson promises, the junior delivers, and quality dilutes somewhere in between. At LUWIZ, it's the opposite: the people who design your visibility are the ones with their hands in the code, the content and the reports.
This continuity isn't a comfort detail. It's what lets us keep our promise of one foundation for two surfaces: when strategy, technical work and content are carried by the same people, nothing is lost between the promise and the execution.
The founders
Cyril Quesnel — Co-founder · GEO & AI Strategy
An expert in organic search and optimization for generative AIs (GEO). He drives visibility strategy for SaaS and B2B clients across Google and AI engines — ChatGPT, Perplexity, Gemini. He's the one who set the agency's founding conviction: SEO and GEO don't split apart, because it's the same problem seen from two angles.
Julien Couderc — Co-founder · Technical SEO
The guardian of the technical foundation: a fast, clean and perfectly marked-up site is what lets engines — classic and generative alike — understand and cite your content. He puts technical work in service of substance, where many treat it as an end in itself.
Marine Ethève — Co-founder · Content SEO/GEO
In charge of content that gets cited — by Google as much as by the AIs. She writes for humans first, and the machines follow: useful, clear and structured content is what turns a page into a reference source. She's the one who makes sure every text serves both surfaces.
The technical side, certified
Julien Couderc, a partner at the agency, holds 32 AI certifications and badges — Google, OpenAI and Anthropic — on top of his ongoing training through IA Pro Academy, which he founded. Proof we don't buy in the technical side from outside: we own it, module by module.

Three areas of expertise, one foundation
The complementarity isn't a slogan: it's the very architecture of the LUWIZ Method. GEO strategy sets the direction, technical SEO builds the base engines can read, and content produces the material Google ranks and the AIs cite. None of these building blocks works on its own.
It's this interplay that explains why we refuse to sell SEO and GEO as two services: with us, they're carried by the same team, in the same move. Splitting the two would mean splitting three people working on the same problem.
"I founded this agency because SEO and AI visibility are the same problem seen from two angles. Most agencies treat them separately. We don't split what's connected."
