Property technology (or Proptech) is one of the fastest-growing industries because, for a long time, this area was highly regulated and slow to change. In recent years, the world has seen extremely fast growth in companies for a few reasons, one of which is the urge to automate business processes and limit in-person interactions due to the Coronavirus pandemic.

Due to the intensive growth and application of the latest technologies, such as data engineering, ML/AI, and augmented reality, Proptech is the domain to be. Startups in this niche have vast investments and resources necessary to bring any creative initiatives to life.

This is also true for the client’s company. Their plan is to conquer the world of property investment and maximize profits through price forecasting, in-depth analysis of historical data and trends, and a system of smart recommendations to improve facilities and increase ROI.
