(0 review)Web, Mobile, Desktop & TV applications that meet your ambitions
Our mission, in short. We are not an agency that delivers code and disappears. We build products and install the methods so that you can build others without us. Engineering, industrialization, skills transfer. All powered by a mutualized R&D where every project benefits from the work done for all others. We build. A new product, a platform, a business component. Regardless of scale. You need it to hold up from day one without burning your budget on foundations. Our technical base absorbs the common infrastructure (auth, CI/CD, monitoring) so that every euro invested serves your business value, not plumbing. What we put in place today is designed for what you will launch in 12 months. We modernize. Legacy slows you down. Every new feature takes three times too long, nobody dares to touch the historical code. We audit, prioritize, migrate in blocks without stopping production. No 18-month big bang. Deliverables visible every two weeks, and an IT system that becomes a lever again instead of a burden. We structure. You know how to produce, but not yet at scale. Conventions vary from one developer to another, deployments are manual, quality depends on who coded. We intervene on your methods as much as on your code: maturity audit, implementation of standards, pipeline automation, team training. The goal: that your production capacity survives our departure. Robust and scalable hybrid React & Next.js / React Native architectures that evolve with your business. Real agility and cutting-edge technical support, from product vision to go-live.Looking for work in NextJS DevelopmentLocated in Suresnes, FranceFrom €3,000 for NextJS DevelopmentWorked in Telecommunications (+3)Speaks English, French1-10 membersZento

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.Looking for work in NextJS DevelopmentLocated in Nantes, FranceFrom €3,000 for NextJS DevelopmentWorked in Industrial Goods & Services (+8)Speaks French, English51-200 membersHeko Lab
5(1 review)The tech and product partner to design your web, mobile, and business applications
Most tech projects don't die from a bad idea. They die from poor execution. Unavailable freelancers, agencies deploying juniors, no-code that crashes under load. The market won't wait. We design, develop, and maintain your web, mobile, or business application with the rigor of an in-house team, the flexibility of a freelancer, and none of the recruitment delays. A hands-on CTO involved in every project, from architecture to product strategy. No intermediate layer between decision and execution. 100% senior, 0% turnover in 5 years. A stable, seasoned, self-managed team. Code review, automated testing, CI/CD: quality is systematic, not optional. Operational in 24h, MVP delivered in 2 to 6 weeks. You see the product advance sprint after sprint. You adjust the course continuously. A business, product, and domain vision. We challenge your functional choices, think about the user experience, and design the interfaces. Not just developers: a product perspective at every stage. AI integrated where it shines. Conversational agents, AI workflows, RAG, LLMs—we design end-to-end AI systems or integrate AI into an existing product, with rigorous control over costs and results. A prepared handover. When you are ready to internalize, we help you recruit and organize the handover. Our goal: to make you autonomous, not dependent.
