Company overview
We care about the city we live in. At Theoremus we have a common vision that we want to share, and to live in cleaner and better cities. We know that to achieve this, we need to combine skills and passion in a new way.

Additional information:
Mobility and waste management are the two largest areas in a city, taking up the largest percentage of the budget. We learned a lot about these areas and understood how technology can be implemented in their management.
At Theoremus, we use various methods from the fields of machine learning, geospatial analytics, and optimization techniques. We have built state-of-the-art data-driven systems that build over time through data science techniques.
