How do you turn complex water data into something that can be shared, understood and used across organisations?

The Aquafin project

I think the most important lesson I’ve learned is to give things away, to trust people with big responsibilities.

Gert De Tant, CEO

Don’t try to prevent failure.
Design for recovery.

Data Engineer Hannes explores what happens when things go wrong in a live system

.NET is part of Sirus’ DNA.

The .NET Team

With M365, the focus isn’t just on deep technical development. It’s about thinking on a higher level, which brings its own set of challenges.

Meet the M365 Team

We leave the campground cleaner than we’ve found it.

The Sirus DNA

I feel like I can grow at my own pace here at Sirus. I get the time to learn without being rushed and I love that.

Valentin Ponthieu, Full-Stack Developer

At Sirus, we aim to use data to drive improvement, give citizens more insight, and bring transparency back to the forefront.

Meet the Data Team

Smart Company Project: Aquafin

Sirus and Wortell assist the City of Lokeren with expertise in molding this project into a workable packagare. The resources, man power, and money we are investing now will later be doubled and thickly regained.

Smart City Project: Lokeren

Thanks to the collaboration with a team of experts we were able to build not only a brand new IoT platform, but a truly interoperable platform that is actively used to share data between VMM and it’s partners.

Smart Company Project: VMM

Another aspect we really liked about this collaboration with Sirus was the involvement of the developers. They were clearly thinking along to understand our business and wanted to help in creating the optimal solution adapted to our needs.

Smart Company Project: Constructiv

Cities are facing a lot of challenges, but I think the biggest challenge of them all is how to gain correct data. That is exactly why we are using the Smart City Data Platform, to combine all of our data from different sensors on one platform.

Smart City Project: Brugge – Leuven – Roeselare
