Web agency in Rennes
Telecoms, imaging, cybersecurity and a large student population: the Rennes Atalante technopole shapes a market that prefers proof to slogans. We build sites that show the proof, remotely from La Rochelle.
Where design, engineering and search meet
Years of web experience
In-house web experts
Live websites
Layouts that organise complexity
Readable by an engineer and a buyer
A technical offer needs a page hierarchy that serves two readers at once: the engineer who checks details and the executive who decides. We set up that hierarchy in Figma before any colour is chosen, then add the visual identity on top.
Motion that explains
Steps revealed as visitors scroll
A process, an architecture or a product cycle becomes easier to follow when it appears step by step. We build those sequences with light animation files and scroll interactions, and keep them restrained so readers never wait for an effect to finish.
Clean code, content you control
Built by the people who drew it
Because one team designs and builds, the component library follows the mockup closely. Your marketing people then assemble new sections from it on their own, and there is no maintenance retainer to keep the site up to date.
Technical SEO and AI answers
Precise queries, precise pages
In specialised fields, a few exact searches matter more than a flood of generic ones. We match each of them with one page, check the technical base, add Schema.org markup, and write short factual passages that a ChatGPT answer can lift.
Landing pages for launches and events
Built around a single action
A webinar, a white paper or a trade show needs a page that does one thing. We prepare it with a short form, tagged links and a connection to your CRM, so every sign-up arrives with the campaign that produced it.
Turning expertise into demo requests
Proof beside every call to action
Technical buyers want evidence before they act. We put references, specifications and a clear next step in the same view, then follow the figures after launch and test changes one at a time.
AI Visibility and AEO
Times are changing, and so is your online presence. We optimize your site for AI crawlers.
Increase in platform registrations
Increase in driver's license package sales

Frequently asked questions
Should one agency handle web design and development for a Rennes tech company?
Usually yes, because nothing gets lost in translation between mockup and code. In Rennes, where many technology firms employ their own engineers, the boundary can be settled in the first conversation, for instance with reusable components they extend. Mazette.co designs and develops in-house, so either route stays coordinated.
How can a Rennes technology company get cited in ChatGPT answers?
Assistants build answers from sources they judge reliable, so the aim is for your own pages to be among them. For a company in Rennes selling telecom or security products, clear structure, precise statements about what you do, structured data and a consistent presence across the web all help. Nothing guarantees a citation, which is why we check the answers again after launch.
Does a Rennes company need an agency based in Brittany?
Not for the work itself. Design reviews, content and approvals all happen online, and Mazette.co keeps French hours, so a call fits into the same working day. The agency is in La Rochelle, and the large majority of our projects run remotely, whether the client sits in Brittany or elsewhere.
