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.

VP Marketing @Paradox
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%!

Jules Ratier
CEO @Koncile
Gemeos delivered a showcase website that met our standards, while still working within a pretty tight timeline. Their process was efficient, and they were available, attentive, and very responsive throughout the project. They’re a highly complementary and very capable duo. Highly recommend!
Thibaud Bertrand
Head of Marketing @Side
“Great Webflow agency. Available, attentive, and responsive. We brought them in to redesign our Nuant.com website, providing the Figma mockups. We’re very happy with the result, and their Webflow expertise is a real asset.”
Leo Carli
Product Marketing Manager @Nuant
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 Duffaut
CEO @Noota
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 Arod
Founding Partner. Asset & Risk Management @Avnear
Gemeos worked on the Webflow integration as part of our website redesign, with the goal of giving our Growth team back control over landing page creation and improving web performance and SEO. I highly recommend Sandro for his availability, responsiveness, teaching approach, and, above all, his understanding of our business needs.
Florian Corteel
SEO Manager @Finary
Thanks to the whole team, always going the extra mile to push the boundaries!
Florent Darrault
CMO @Cureety
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 BERNARD
CEO & Founder @AssessFirst
Sacha & Sandro worked on the redesign and migration of our website with a few clear goals: create a unique, differentiated visual identity, clarify our message and value proposition, smooth out the customer journey, and ultimately generate more business opportunities. We’re very happy with the result, and the numbers speak for themselves. Sacha & Sandro are skilled, committed, conscientious, passionate, and they see things through to the end. I highly recommend them!

WhattheFAQ?
What is Gemeos?
Gemeos means "twins" in Portuguese. Founded in 2021 by Sandro and Sacha, twin brothers with complementary skills: strategy and growth on one side, design on the other.
Gemeos is a Design & Tech agency, specializing in Webflow website creation, SEO, conversion optimization, and growth strategy for ambitious companies.
The team now has 15 people covering the full stack: design, development, SEO, copywriting, and project management. One point of contact, all skills in-house.
How is Gemeos different from other digital agencies?
Most agencies do either design, SEO, or dev. Gemeos covers all three in-house, with a performance mindset at every stage. We don’t just ship a site and disappear — we measure what converts, test, and iterate.
What types of companies do you work with?
We primarily work with B2B startups and scale-ups in growth mode, across France and the US. Our clients have typically moved past the MVP stage and want to level up their digital presence to accelerate acquisition.
We’ve worked with companies like Tracktor, Homunity, AssessFirst, Modjo, and Finary. If you’re a startup or scale-up with digital growth challenges, we’ve likely tackled a case similar to yours.
What services does Gemeos offer?
Gemeos covers the full digital growth stack: from website creation and conversion optimization to SEO, branding, and custom-built tools.
Do you offer standalone projects or only ongoing engagements?
Both. We work on one-shot projects (site creation, redesign, SEO audit, landing page) as well as monthly retainers for clients who want a long-term growth partner.
Most of our clients start with a one-shot project and move to a retainer once the foundations are in place. That’s the model that consistently produces the best long-term results.
Do you work with clients outside France?
Yes. Gemeos is based in Dubai and works with clients in France, the US, and across Europe. Our setup is 100% remote — all projects are managed via Slack and Figma with no loss of quality or responsiveness.
We work in French for French-speaking clients, and in English for US and international projects. Several of our deliverables are produced bilingually in French and English.
What budget should I plan for working with Gemeos?
Our projects start from €2,000 for a focused engagement (landing page, audit, art direction). A full website project typically ranges from €8,000 to €30,000 depending on scope. Monthly retainers start at €1,500/month.
These are indicative ranges. The fastest way to get an accurate estimate for your project: book a 30-minute discovery call with us.
You can also visit our Plans page to learn more.
How does a project with Gemeos work?
Every Gemeos project follows the same five-step process, from discovery to go-live.
A project lead coordinates every step and makes sure milestones are met on both sides. You get a dedicated client space with real-time progress updates and a Slack thread for day-to-day communication.
How long until I see results?
It depends on the service. A delivered website has an immediate impact on credibility and direct conversions. SEO takes 3 to 6 months for measurable results. CRO and A/B testing produce insights within 4 to 8 weeks of the first tests going live.
What guarantees do you offer on results?
We don’t promise #1 on Google in 30 days and we don’t guarantee a specific conversion rate upfront. That would be misleading.
What we do guarantee: a rigorous method, goals defined together from the start, transparent reporting on what’s working and what isn’t, and the ability to course-correct fast.
Do you have references in my industry?
We’ve worked across a wide range of sectors: B2B SaaS, Finance and Fintech, Real estate, HR and recruitment, Industry, and professional services. Finance and Fintech represent a growing share of our work, with clients like Homunity and Finary.
If you want to know whether we have specific references in your industry, the easiest thing to do is mention it during a discovery call or browse our Case Studies page.
We’ll show you the projects most relevant to your context.
