About Us

Zoomer Analytics is an independent IT consulting company based in Zürich, Switzerland. It has been founded out of the frustration of how most traditional firms misuse software like Excel and MATLAB® to build complex analytical tools. We believe you should rather spend your money on the creation of applications that solve actual business problems than on license costs and other inefficiencies typically caused by these tools.

Thanks to our agile team with zero overhead, we are able to deliver solutions from prototypes to productive systems in less time and for a fraction of the costs when compared to more traditional approaches often seen in the world of corporate IT. Our core competence is the implementation of applications for quantitative finance based on the Python programming language.
