A software development company in Geneva

At the origin of the creation of the software development company SZ Informatique SA lies a simple observation: users want their IT systems to meet their needs… Yet, in practice, companies often feel like they have to “adapt to their computers”!

It was therefore only natural that SZ Informatique specialized in creating custom solutions.

The software development company has been operating in French-speaking Switzerland since 2000 under the leadership of Stephan Zwettler, formerly an independent IT consultant. Our team, organized as an engineering office, offers comprehensive solutions.

Passionate and innovative, we rarely do the same thing twice. Our vision focuses on new and innovative solutions, which is why we take existing solutions that already meet part of your needs into account and enhance them with our expertise.

Over the years, we have established long-term collaborations with major companies in the region, both public and private. In doing so, we maintain, develop, and renew applications used by hundreds of people.

We analyze your entire current IT system, assessing how well it aligns with your needs and expectations, and translate this into concrete applications and tools to implement.

Off-the-shelf commercial products, often requiring costly setup, are no longer sufficient to meet the growing demand for efficient IT solutions.

True, tailored, effective, and advantageous advice can be provided by SZ Informatique and its team of qualified professionals, trained in cutting-edge technologies and working closely with their clients.

Because we are committed to providing the best experience for our clients, each project is managed by a single primary contact—someone who knows you and your project—throughout the entire lifecycle of the installation.

How to create your custom software with us?

It all begins with a need
You have the ambition to stand out and/or optimize your activity, which is why you have chosen to call on a custom software development company. You have an idea and you present us with more or less detailed expectations. What you are looking for is a partner, an external supplier with whom you can collaborate to bring your project to life.
Things are becoming clearer
Your project may not yet be well defined, you have many questions, to which we will be able to provide answers, allowing you to imagine your custom solution. We discuss together to establish an analysis document that will meet the specifications submitted in order to model from A to Z all the solutions you need in detail.
From need to solution
Once the project has been defined and signed, our team moves into the development phase where we regularly deliver our work to you so that you can carry out your first tests. This allows us to refine gradually based on your feedback. We move forward together by iterating between our development work, your tests and our adaptations, in accordance with the AGILE method.
Your teams at the heart of the project
In all our projects, we include a team of beta testers among your employees, the end users for whom the solution is designed. Because your satisfaction is our priority, we train your teams in the use of your new software to ensure optimal integration.
