Florent DarraultCMO @Cureety 
“We worked with Gemeos in the summer of 2024 to redesign Modjo’s marketing site and better reflect the brand’s new positioning. The collaboration was incredibly efficient, the agency was highly responsive and adapted to every unexpected challenge. With limited resources on our side, right in the middle of summer, we launched the new site in just six weeks. Site visit engagement increased by 58%!”
Thomas BeylotVP Product @Modjo 
“Gemeos delivered a showcase site that met all our requirements while working to quite tight deadlines. Their methodology was efficient, and they remained available, attentive, and highly responsive throughout the project. They are a complementary and very skilled duo. Kudos to them!”
Thibaud BertrandHead of Marketing @Side 
"Most agencies make a great first impression and sell you the dream in those early conversations, but that illusion fades fast once the contract is signed. With Gemeos, it’s different. Gemeos are professional and genuinely committed to doing things right and fast. I really recommend them. And this is the first time I’ve ever recommended an agency.
Quentin MayetVP Marketing @Paradox 
We entrusted Gemeos with a full website redesign and migration, and everything went incredibly smoothly. What stood out most to us was the quality of the art direction: a truly premium, cohesive visual direction, with a clear visual identity and highly polished choices throughout, typography, colors, iconography, pacing, hierarchy, and more. You can tell they have great taste, and above all, a real eye for detail on every screen. On top of that, the team is incredibly responsive and very experienced: they know both design and the technical side inside out. I’d recommend them without hesitation.
David BERNARDCEO & Founder @AssessFirst 
"We worked with Gemeos for several months on the redesign of our site and the launch of our new Taalent.ai offering in the U.S. market. The team was able to combine strategic vision, high-quality execution, and great responsiveness throughout the project. An effective collaboration that I’d recommend without hesitation."
Alexandre DuffautCEO @Noota 
"The Gemeos team perfectly understood our challenges and supported us well beyond a simple site redesign. The result is modern, clear, and above all much more aligned with our positioning. A responsive, involved team that comes up with great ideas. I recommend them without hesitation."
Céline CheminalMarketing @Presti

Efficiency, structure, and performance. Gemeos managed to translate Avnear’s identity into a website that exceeded our expectations. Client feedback has been unanimous. The team showed remarkable agility in adapting to our requests and our high standards. A trusted partner we’d recommend without hesitation. Our site is a masterclass in building trust.
Charley ArodFounding Partner. Asset & Risk Management @Avnear 
"I'll be honest: we had nothing. A website thrown together in 2023, no identity, zero visibility on Google. We were selling wealth structuring with a website that proved the exact opposite. Today, it's coherent. It took time, but it's coherent."

Gemeos supported us through the redesign and migration of our site with a sharp understanding of our growth challenges. The result is a site that is much more aligned with our image, while giving us real autonomy on the marketing side. An expert, responsive team that is a pleasure to work with on this kind of project.
Gatien de BéjarryCMO @Homunity 
"Our positioning is a nightmare to explain. We're neither a broker, nor a comparison site, nor an insurer. It took me five minutes to explain it in meetings. They turned it into one sentence and one diagram. Since then, I use it verbally too."
Tristan DE LA MARTINIEREFounder @Giva 
Very happy with the work! The brief was well structured, the art direction quickly captured our identity, and the Webflow site is a real success. A professional, responsive team that takes the time to talk things through!

Idir AIT SI AMERCEO @TracktorWhat the FAQ?
UX design and UI design: what's the difference?
UX design (User Experience) handles the navigation logic: user journeys, information architecture, wireframes, and the hierarchy of actions. UI design (User Interface) handles the visual layer: colors, typography, components, micro-interactions. One without the other produces either a beautiful but unusable interface, or a functional but unappealing one.
At Gemeos, both are handled in parallel from the design phase onward. We don't deliver wireframes and then layer a design on top afterward: both dimensions are thought through together, which avoids inconsistencies between functional logic and visual execution.
| UX Design | UI Design | |
|---|---|---|
| Goal | Make the journey logical and smooth | Make the interface beautiful and consistent |
| Deliverables | Wireframes, user flows, sitemaps | High-fidelity mockups, design system |
| Typical tools | Figma, Miro, FigJam | Figma, design tokens |
| Core question | Does the user find what they're looking for? | Does the interface make people want to act? |
When should you redo your web design?
Four concrete signs indicate that a web design overhaul is needed: your conversion rate is stagnating despite decent traffic, your site no longer reflects your current positioning, it isn't optimized for mobile, or your competitors have a clearly stronger digital presence than yours.
What shouldn't be confused: redoing the design because you're tired of it, and redoing it because it's holding back growth. The second justifies the investment. The first, rarely.
| Signal | Is a redesign justified? |
|---|---|
| Low conversion rate despite good traffic | Yes, high priority |
| Site not optimized for mobile | Yes, direct SEO and UX impact |
| Company positioning has evolved | Yes, the site should reflect the current brand |
| Load times too slow | Yes, depending on the scale of the problem |
| Founder is visually tired of it | No, not a sufficient reason |
We redesigned Tracktor's site starting from a conversion analysis: the result was a +19% increase in conversion rate without raising the acquisition budget. The full analysis is available here.
How do you choose a web design agency?
The number one criterion is the ability to connect design with performance. A web design agency that only talks about aesthetics without mentioning conversion rates, visual hierarchy, or technical SEO won't help you grow. It will just make you a nice-looking site.
Also check: does it deliver editable source files? Does it have references in your industry or on projects of a comparable size?
| Criterion | What to check | Warning sign |
|---|---|---|
| Portfolio | Measurable results, not just visuals | No case studies with real numbers |
| Technical stack | Maintainable CMS, web performance | Delivered as non-editable static HTML |
| Conversion-focused approach | Asks about your business goals | Only talks about aesthetics |
| Client autonomy | Training, documentation, CMS access | You depend on them for every change |
How much does a web design project cost?
The price depends on the scope: number of pages, level of customization, integrations, animations. For a well-designed startup showcase site, expect between €5,000 and €20,000. For a more complex site with a CMS, simulators, or API integrations, the range climbs to between €15,000 and €50,000.
| Project type | Indicative range | What's included |
|---|---|---|
| Startup showcase site | €5,000 to €15,000 | Design + Webflow integration, 5 to 10 pages |
| Scale-up site with a CMS | €12,000 to €30,000 | Design system, blog, dynamic pages |
| Complex site with integrations | €25,000 to €60,000 | Simulators, APIs, multilingual, advanced animations |
These ranges apply to a specialized agency with a genuine conversion-focused design approach. For a complete view of budgets, our guide to the price of a showcase site on Webflow breaks down the cost items.
How long does a web design project take?
A standard web design project (a 5-to-10-page showcase site) takes between 4 and 8 weeks from the brief to launch. More complex projects with a CMS, advanced animations, or API integrations can take up to 12 to 16 weeks.
| Phase | Indicative duration | What happens |
|---|---|---|
| Brief and scoping | 1 week | Goals, sitemap, references, constraints |
| UX and wireframes | 1 to 2 weeks | Page structure, user journeys |
| UI design | 2 to 4 weeks | High-fidelity mockups, design system |
| Integration and development | 2 to 4 weeks | Webflow integration, animations, CMS |
| Testing and launch | 1 week | QA, responsive, performance, technical SEO |
The factor that extends timelines the most: back-and-forth on the design when positioning decisions haven't been made upfront. The clearer the brief at the start, the faster the project.
Does a web design agency also handle development?
It depends on the agency. Some only do design and outsource development, others cover both. The difference matters: when design and development sit within the same team, iterations are faster, technical constraints are factored in from the design phase, and the final quality is more consistent.
At Gemeos, design and Webflow development are both handled in-house by the same team.
| Setup | Advantages | Drawbacks |
|---|---|---|
| Design-only agency | Deep design expertise | Dependence on an external developer, complex coordination |
| Dev-only agency | Technical expertise | Design is often generic or outsourced |
| Integrated design + dev agency | Consistency, speed, a single point of contact | Less ultra-specialized expertise in each area |
What deliverables does a web design agency provide?
The deliverables of a complete web design project cover three levels: the design files, the live site, and documentation so you can maintain the site independently.
| Deliverable | Format | Purpose |
|---|---|---|
| Design files | Figma with design system | Source of truth, future updates |
| Live site | Webflow published on your domain | Live, optimized, responsive site |
| Configured CMS | Webflow Collections | Independent content management |
| Documentation | Notion or PDF | Usage guide for the CMS and components |
| Technical SEO report | PDF or dashboard | Status of tags, performance, redirects |
At Gemeos, we systematically train client teams to manage their Webflow site after delivery. The goal: for you to be independent on routine updates without depending on us for every change.
