We are a tech company in the real estate domain, offering information on quality, risk and value for every building.


GeoPhy is a real estate data & analytics company that works with a combination of public and proprietary datasets to define quality, value and risk for every building. We are building out a global asset level database that currently covers over 100 million buildings in 50 countries. We offer our data service to investors, lenders and governments, allowing them to better assess risks and opportunities.

In a world demanding ever-greater transparency, real estate remains incredibly opaque. GeoPhy was founded to change just that. On a daily basis, investors, banks, pension funds, consultants, governments and regulatory bodies make real estate decisions based on partial and inconsistent information. Right across the industry the lack of consistent and reliable data has undermined, devalued and destabilised short, medium and long term investment returns.

Empowering our clients

We apply cutting-edge technology to an ever-growing amount of data from a wide variety of sources. Our semantic model for the real estate domain enables advanced analysis and research, combined with machine learning for predictions and forecasts.

Our Team

Adriaan Hoogduijn

Head of Kaunas Office
Q: What do you do at GeoPhy? Tell us more about your role. A: My main role is to oversee our data collection process, ensuring data quality whilst handling huge quantities of data as efficiently as possible. This process focuses on our Delft and Kaunas offices. Q: Why GeoPhy? What attracted you to the company? A: Back when the company was still called Office Rank, I was surprised to find that this was a start-up company involved in something I would have thought would have been around for years. A great idea combined with a sense of adventure to match made me very enthusiastic to play my modest part in helping to build up this company. Q: What is the most important lesson you’ve learned at GeoPhy? A: The question is never IF something can be done, but HOW it can be done. Q: If you could define GeoPhy in one word, what would it be? A: Freedom of thought (3 words actually). Q: What do you do enjoying in your free time? A: Mountain biking, gaming and driving my car across Europe.
