What our customers say

Sandro & Sacha forment le duo d'experts parfait pour reprendre votre site internet de A à Z. Au delà d'être compétents, ils ont su être force de proposition tout au long du projet, un vrai + ! Merci pour cette superbe refonte du site Openeat ;)

Martin Catineau
Head of Marketing @Openeat

Super collaboration avec Gemeos qui a réalisé un redesign de notre site Fabriquons.fr. Échanges très faciles. Sacha est à l'écoute, réactif et force de proposition. Le résultat est très pro. Je recommande l'agence pour vos refontes ou création de sites Webflow.

François Galy
CEO @Fabriquons.fr

Sacha and Sandro delivered a showcase site that met our requirements while respecting fairly short deadlines. The methodology was effective and they were available, attentive and very responsive throughout the mission. They are a complementary and very competent duo. Congratulations to them!

Thibaud Bertrand
Head of Marketing @Side

“Gemeos and in particular Sandro are working on Webflow integration as part of the redesign of our website. The main purpose of this change: to give back control of the creation of landing pages to the Growth team, to facilitate integration by setting up a logic of components based on our design system, and finally, to work on webperf and SEO issues. I strongly recommend Sandro in particular for his availability, his responsiveness, his pedagogy and finally his understanding of our business challenges.”

SEO Manager @Finary

“We worked together on multiple projects: website, ads, UX/UI, print and even illustration, I have always been 100% satisfied with Gemeos. In addition to their high quality know-how, they are rigorous, punctual and pleasant. It is a pleasure working with you!”

Benjamin LATTRON
Head of Marketing @Hesus

“A big thank you to Sacha and Sandro for their branding intervention and Creation of a site. The result is of excellent quality and they have redoubled their creativity.”

CEO @Lane Digital Consulting

“Sacha & Sandro worked on the redesign and migration of our site with the following objectives: to have a unique and differentiating visual identity, to clarify the message and the value proposition, to streamline the customer journey and ultimately to generate more business opportunities. Very happy with the result and the numbers speak for themselves. Sacha & Sandro are competent, involved, conscientious, passionate and go the extra mile. I highly recommend them!”

CEO @Tracktor SAS

“Top team, exceptional quality of work, we recommend not 100% but 1000%, thanks to Sandro and Sacha for creating our website and for their support and follow-up on referencing topics. In short, they are the ones you should use for any digital project.”

CEO @Les Parisien Trainers

“We sincerely thank Sandro and Sacha for the creation of our website. In addition to being professional, attentive and competent, they fully understood our needs from the first discovery of our project. Their passion for this profession is unquestionable. I definitely recommend it for anyone who wants to have an attractive and professional website.”

Manager @Ad Rents Motors

Any questions?

Who are the developers?

You might be surprised to hear this, but Gemeos is actually a 2-person agency. This means you'll be working directly with co-founders Sandro and Sacha.

We made this choice to ensure impeccable quality of service and to be as close as possible to our customers.

What's different from a traditional development agency?

Using no-code tools allows us to iterate quickly, so your product can evolve in an agile and cost-effective way.

Is there anything I could change?

Of course, we build sites with component logic, so you can modify and/or create new pages on your own, and we include training videos for all our projects, to make sure you're comfortable with the Webflow interface once we've delivered your project.

How do you work?

Lorsque nous commençons un nouveau projet, nous créons une page Notion et donnons accès à nos clients. Ils y retrouvent toutes les informations nécessaire au bon déroulement (étapier de suivi, coordonnées pour nous contacter, lien google meet, lien vers les différents outils avec les mdp associés, lien Figma, devis, factures, etc). Ce fonctionnement permet de centraliser toutes les informations et les documents pour vous donner un maximum de visibilité et ainsi vous faire gagner du temps.
