KATE’s Story

KATE Innovations was established in 2016 by Rutger Janssen, Erik Schlooz and Roderik Gerritsma out of frustration with the inefficient valuation process of commercial real estate. When it comes to adapting to the digital world of today, the commercial real estate sector is lagging behind. The disruption of this sector calls for innovative changes. The answer to the problem is KATE Innovations. KATE develops software that organises the whole valuation process from A to Z. In this way, real estate companies are able to structure their data, optimise their workflow and develop new and future-proof business models. In addition, KATE offers IT solutions that enhance the collaboration of advisors, banks, and property owners within the eco-system of the real estate sector.
