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%!
Thomas Beylot
VP Product @Modjo
“Gemeos are the perfect experts to take over your website from A to Z. Beyond being highly skilled, they were proactive and came up with great ideas throughout the project, a real plus! Thanks for this fantastic Openeat website redesign ;)”

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!

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!

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?
Who are Gemeos' founders?
Gemeos was founded in 2021 by Sandro and Sacha Da Silva, twin brothers with complementary profiles. Sandro leads the agency's strategy, growth, and business development. Sacha heads design: branding, art direction, UX/UI. Two minds, one vision: to build digital presences that truly perform.
This foundational complementarity is not a marketing claim: it's the agency's operational model. On every project, the strategic and creative dimensions are conceived together from day one, not assembled as an afterthought.
How was Gemeos created?
Gemeos was born in 2021 from a simple realization: too many digital agencies separate what should be united. Design on one side, SEO on the other, and conversion nowhere to be found. Startups ended up with beautiful websites that didn't convert, or SEO-optimized sites that were visually unremarkable.
Sandro and Sacha founded Gemeos to offer an alternative: an agency that treats design, development, SEO, and conversion as a coherent whole, driven by a single objective — client growth.
In four years, the agency has supported over 250 clients and built a team of 15 specialized employees.
Why the name Gemeos?
Gemeos means "twins" in Portuguese. It's both an obvious choice and an intentional one. Obvious because the agency was founded by two twins. Intentional because the name reflects the duality at the heart of our approach: design and performance, creativity and rigor, aesthetics and conversion.
We could have chosen a generic name or an invented contraction. We preferred something that reflects who we are.
How do you work as a team?
In parallel, not in sequence. At most agencies, design waits for the brief, development waits for design, and SEO comes last to "optimize" what has already been built. At Gemeos, departments work together from the initial scoping phase: Designers integrate SEO constraints into design decisions, and Bryan anticipates the technical implications of creative choices.
Practically, this means fewer back-and-forths, shorter deadlines, and websites where design and performance are not at odds. Project Managers orchestrate the entire process and ensure that each deliverable is completed on time and to the expected quality.
What is Gemeos' vision?
To become the leading digital growth partner for B2B startups and scale-ups in France and the United States. Not just another agency in a saturated market, but a player that combines design, tech, and growth into a coherent and measurable offering.
In the long term, the vision is to build a structure capable of supporting companies from their first website to their exit, with expertise that evolves with their stage of growth. That's why we invest so much in Finance and Fintech verticalization: it's a sector where digital credibility is a direct growth driver, and where few agencies have true industry expertise.
What exactly does "Built to convert. Built to last." mean?
This is our two-part promise. "Built to convert": everything we produce is designed to generate measurable results. A website, a landing page, an SEO article, an artistic direction: each deliverable has a performance objective defined upfront. "Built to last": we don't deliver solutions that become obsolete in 18 months. We build solid foundations, a sustainable architecture, and a coherent brand identity that endures.
Practically, this means we don't take shortcuts. A website delivered quickly but poorly optimized technically will cost you more to fix in 2 years than to do it right from the start.
