KATE’s Story

KATE Innovations was founded in 2016 by Rutger Janssen, Erik Schlooz and Roderik Gerritsma out of frustration caused by the inefficient appraisal process of commercial real estate. When it comes to adapting to today's digital world, the commercial real estate sector is lagging behind. The disruption of this sector calls for innovative changes. That's why KATE has developed software that organises the entire valuation process from A to Z. This allows real estate companies 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 between consultants, banks and property owners within the real estate industry ecosystem.
