New websites and rebuilds, from first idea to launch. Fast, accessible and made to last.
What we actually do
From first sketch to launch, and long after: your project stays in the same hands.
Creation
Built around your business, not a template. Modern design, fast on every screen, with today's web technologies under the bonnet.
Hosting & Maintenance
Cybersecurity is becoming a strategic issue, and no website is invulnerable. Our answer is simple: keep everything up to date. Software, SSL certificates, security patches and backups are followed over time, to reduce the risks without claiming to eliminate them.
SEO
Being visible on Google isn't magic. It's technique, well-structured content, and patience. We'll guide you through it.
Training
Understand the web, run your own website, gain independence. Our training starts from your level and leaves you with methods that last.
Audit
A full check-up of your website: performance, accessibility, security, SEO. You see exactly what can be improved.
Automation & AI
Repetitive tasks are made for machines. We interface the tools on the market, from Microsoft Office to AutoCAD, and put AI where it is genuinely useful: processing your documents, summarising information, modelling your data.
→ Get in touch: we will explain the challenges of tomorrow’s worldWhat is retrofit?
Your website is 5, 10 or 15 years old. It still runs, but it's slow, awkward on mobile and hard to update. Your content hasn't aged: it's the engine that needs replacing.
Retrofit is exactly that: we keep what has value — your text, your images (okay, the photos probably need to be retaken at a higher resolution), your identity — and we rebuild everything else with today's technologies.
No need to start from scratch. No need to rethink everything. We take what you have and make it modern, fast, and accessible.
No website? No worries, we'll handle it.
No idea? We'll handle that too.
No photos? We'll handle that too.
No brand guidelines? Don't panic...

Frequently asked questions
What we're asked most often before getting started.
What does a website "retrofit" mean?
A retrofit means taking your existing website — your texts, your identity, the content that has real value — and rebuilding the entire technical side with today's technologies. You keep what works, and we modernise the rest: speed, mobile display, accessibility and search engine ranking.
How long does it take to modernise or build a website?
It depends on the size of the site and the amount of content. A showcase website is usually delivered within two to four weeks. A retrofit can be faster, since the content already exists. We give you a precise timeline right from the initial analysis.
I have no website, no photos and no brand guidelines — is that a problem?
Not at all. We take care of everything: design, photos, visual identity, copywriting. You don't need to come with a complete brief — a conversation about your business is enough to get started.
Will my website be visible on Google?
All our websites are built with careful SEO from the very start: clean structure, speed, well-organised content and appropriate markup. Visibility then builds up over time, and we support you in growing it sustainably.
Do you also handle hosting and maintenance?
Yes. We offer reliable hosting with an SSL certificate and backups, along with ongoing maintenance: updates, fixes and improvements. You have nothing to manage technically — we take care of everything.
Do you only work in Alsace?
We are based in the Thur Valley and work remotely with clients everywhere — in French, English and German.
