We build and invest in real estate technology.

Real estate is a $200 trillion global asset class. It's also one of the last remaining service industries yet to be truly reshaped by technology. And it’s our view that the creation of end-to-end experiences is the next frontier.

The future of real estate is connected.

Over the past two decades, innovation across the real estate space has found itself hamstrung by growing levels of product fragmentation and complexity. This has meant that an era marked by bold promises of digital transformation is yet to deliver on its true potential.

It is our view that meaningful digital innovation in real estate is not only a question about what one can build - but more about how one can bring products, technologies and people together with coherence, simplicity and purpose.

That's why we created Castle One.

It’s about creating integrated experiences – where everybody wins.

Consumer journeys in the real estate space are shaped by a number of role-players, suppliers, disciplines and regulatory frameworks. The result is that truly customer-centric product innovation is difficult and many essential ingredients to meaningful change remain beyond the reach of innovators.

Add to this the economics and risks involved in doing something new – and you have an industry with a sincere desire to move forward, but limited vehicles to get there.

Castle One was created to overcome these challenges.

It is our conviction that frictionless, end-to-end experiences are only possible when you bring enough like-minded people, products and companies under one roof.
