Our mission is to make the housing market transparent so that supply and demand will be better matched in the future. By making trends and developments in the rental market visible, we help real estate professionals to make important choices. This limits investment risks as much as possible.

Data sources 

and many more... 

Realstats originated from a collaboration between Clappform and Pararius.

Clappform is a data analytics platform for the real estate industry. This flexible cloud-based platform makes it possible to create valuable insights based on both structured and unstructured data, thereby integrating advanced data analytics within companies. By using knowledge and expertise from different sectors, Clappform helps to integrate and develop AI solutions for making business processes smarter.

Pararius has been matching the housing market’s supply and demand since 2006. It is the largest property portal in the Netherlands with more than 2.5 million visitors per month. All professional real estate stakeholders such as estate agents, project developers and housing associations can advertise properties for sale and rental properties on Pararius. This means the listings on the portal stay up-to-date, fair, complete and without any extra costs, totally accessible for home seekers. As a result, more than 70,000 people find new homes annually on Pararius!
