(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

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.
