WHO WE ARE Since 2015, theTribe has supported SMEs, mid-sized companies, associations and public-sector organizations in creating, redesigning and evolving their strategic digital tools through web, mobile and AI development. Based in Nantes and Paris, our team of more than 60 senior experts covers the entire product development lifecycle: scoping, design, development, deployment, redesign, taking over existing projects and maintenance. Since our beginnings, hundreds of clients have placed their trust in us, including Accor, Veolia, Inserm, HomeExchange, Gens de Confiance, Eskimoz... OUR VISION At theTribe, technology is useless if it does not address a genuine business or user need. Our approach is built around three pillars: 1/ Understand before building Every project starts with a scoping phase that clarifies your business and operational challenges. This ensures that we build the right tool, not just a tool that works. 2/ Technology serving the business Technology for technology’s sake does not interest us. What we enjoy is finding the solution that fits your needs and delivers the best results with the best ROI. 3/ Make AI an accelerator, never an autopilot AI now runs through every aspect of our method: faster scoping, higher-quality code and accelerated prototyping. But the product decisions that matter remain in the hands of our teams and are never delegated to a model.No workLocated in Nantes, FranceFrom €3,000Worked in Industrial Goods & Services (+8)Speaks French, English51-200 membersWizz You

RecommendedTop awardedWizz You , a web agency in Toulouse. We support companies all over France. You are comparing several agencies, so let's get straight to the point. With us, you have a single point of contact from the beginning to the end of the project. No need to repeat the same information to three different people. You always know who to contact and where your project stands. We mainly work with SMEs, retailers, and entrepreneurs who are looking for simple answers, met deadlines, and long-term support. What we do Showcase websites, e-commerce stores, custom platforms, iOS and Android mobile applications, natural referencing, Google Ads campaigns, conversion-oriented design, and solutions based on artificial intelligence when it brings real value. Our way of working It all starts with a conversation. We take the time to understand your business, your objectives, and your constraints before proposing a solution. Then, we provide a detailed quote, with a clear budget, defined deadlines, and no hidden costs. Why our clients stay Because we don't try to sell unnecessary services. Because we remain available after launch. And because we sometimes say that an idea is not the right solution when we think we can save you time or money. Based in Toulouse, we work with companies throughout France. The first discussion is free and without obligation. At worst, you leave with some useful advice.
