Zen systems
Custom Application Development
We assemble a team of 2 to 10 specialists tailored to each project based on your requirements. We also choose the right technologies accordingly. We have experience developing for established companies, startups, and critical infrastructure.

Every business is unique, and standard software solutions often do not meet specific requirements. Custom software applications allow you to precisely manage processes, improve efficiency, and offer better services to your customers. Whether you need a complex web system for various sales, analysis, and creation, an internal management tool, a mobile app for customers, or a website, our custom solutions will give you a competitive edge.

Our developers have extensive experience in creating applications for various industries and company sizes. We adhere to the highest quality standards to ensure that your application is not only functional but also secure and user-friendly. We use the latest technologies and development methodologies. We can quickly respond to your needs and adapt to the changes that your business requires. We are flexible and tailor our services to your specific needs and budget.

Before deployment, we conduct extensive testing to ensure that your applications function flawlessly in all scenarios. We ensure a smooth transition and integration of the new application into your operations with minimal disruption, and in addition to development, we can also take care of IT networks, data backups, and security. We provide regular updates and enhancements so that you can take advantage of the latest features and ensure the long-term relevance of your software.

Luucy and the architects
We are honored to have been part of the development of the Swiss platform Luucy from the beginning. This web application serves to display and build interactive spatial zoning plans and real estate development projects. Luucy offers an expanding collection of information from global and Swiss information sources—3D models of current buildings and forests, terrain, a wide variety of maps, and visualized data about specific features of given territories. Leveraging more than a hundred features, users can view plans for construction changes, compare options, model new structures, combine different ideas, and evaluate these designs within economic, landscape, legal, and quality-of-life contexts—such as through shadow visualization and various camera views.
Bageterie and New Technologies
Zen Systems develops applications for companies within the Crocodille group: Bageterie Boulevard and Pizza360. For both fast-food chains, we have developed a mobile app, a web e-shop, a KDS (kitchen display system), and a CDS (customer display system). Our solutions integrate with parts managed by Bageterie Boulevard itself as well as with solutions from other suppliers. We provide long-term support to Bageterie Boulevard and Pizza360 in technological solutions—not only through software development but also through consulting on IT network setup and DevOps.
