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.
