What we offer

Our support

Positioning analysis

A preliminary step before any design or redesign: we audit your competitive landscape and your positioning on search engines, so we start from a clear baseline.

Websites and platforms

Showcase, corporate, editorial, e-commerce, web applications. Performance and conversion by default.

Performance audit

A complete diagnosis of loading speed and browsing fluidity, with a quantified, prioritized optimization plan measured in real-world conditions.

Funnel redesign

Redesign of the conversion journey, from form to payment, validated through comparative testing with your visitors.

Compliance

Legal and GDPR compliance: legal notices, cookie management and protection of your visitors’ personal data.

Technical modernization

Moving an aging website to an architecture that is faster, safer and easier to evolve.

Design system

A consistent, documented, reusable component library, ready for your teams and your future developments.

SEO, GEO and content

Google rankings, visibility in answer engines and editorial strategy, built on content structured to be properly understood.

Our commitments

A VIP service

Everything belongs to you.

The code, the content, the data: you walk away with a website that is yours, hosted in France, with no monthly license fees and no vendor lock-in. If one day you want to switch providers, you can.

Your teams stay autonomous.

We deliver a clear publishing tool and train your teams. Editing a text, adding a page, publishing a news item: all of it gets done without calling us back.

A solid foundation built to last.

We build on recent technologies where security and performance are there from the start. In concrete terms, a website that stays fast and reliable even as you enrich it over the years.

Branding

Branding, design system, brand voice

A strong digital brand is more than a logo. It is a coherent system, from positioning to motion, documented to last and to be upheld by your teams. We work in five phases and, at the end, deliver a digital, interactive brand guide that is easy to consult and to keep alive.

01
Brand strategy

A short, dense phase: positioning, values, expressive territory, audiences. The foundation that guides every creative choice.

02
Visual system

Logo, palette, typography, iconography, composition and imagery principles. A coherent, adaptable and durable identity.

03
Design system

A coherent, documented component library that establishes a common language between your creative and technical teams.

04
Brand voice

An editorial guide: tone, vocabulary, registers, examples and counter-examples. A recognizable voice across every channel.

05
Motion brand

Animation and transition principles that bring the identity to life. Motion as a natural extension of the visual system.

Frequently asked questions

What types of websites do you build?+
Showcase sites, corporate sites, editorial platforms, e-commerce, member areas, donation areas, business web applications. Always bespoke, designed for performance and conversion, never built from a rebranded generic theme.
Are SEO and GEO built in from the design stage?+
Yes, from the first mockup. Google rankings addressed through both content and structure, and GEO so you get cited by answer engines such as ChatGPT, Claude, Perplexity or Gemini. Visibility is not an audit added after the fact, it is a requirement built in from day one of the project.
Do you also handle print, photography and video?+
Yes. Complete visual identity (logos, brand guidelines, web and print variations), design system, motion design, video shoots and professional photo shoots. A multidisciplinary team under one roof, with no need to coordinate five different vendors.
WordPress or modern technology: how do you choose?+
It depends on your publishing pace, the autonomy you want for your teams and your performance requirements. WordPress remains relevant for intensive publishing by a non-technical team. For websites where speed, security and business features matter, we recommend the highest-performing web technologies on the market. We decide based on your actual context, without bias.
How is GEO performance measured?+
With dedicated analysis tools that query answer engines on 30 to 50 strategic questions in your sector. We track the citation rate, the accuracy of the information returned and the share of voice against competitors. A typical goal is to earn 1 to 3 citations per 100 sector questions.
What hosting do you recommend?+
Sovereign French or European hosts: Scaleway, OVHcloud, Infomaniak, Hetzner. On eco-design, Scaleway DC5 reports around 0.3 g of CO2 per request. Backups, security and updates are included. You remain the owner of your code and your data.
How long does a redesign take?+
Plan on 12 to 20 weeks in general, from the scoping audit to launch, depending on the functional scope, the volume of content to migrate and the level of customization of your component library. We work through milestones validated with you, with no opaque tunnel.
Who owns the website and its content?+
You do, entirely. The website, the content and the brand source files are handed over to you. Everything remains reversible: no artificial dependency on our firm, you can take back control or change providers whenever you wish.
What ROI can you expect from a redesign?+
A high-performance, eco-designed redesign cuts bandwidth by 60 to 80% and improves conversion rates by 15 to 40%, while strengthening search rankings. We also know how to work in phases for tighter budgets.
