HARNESS: from commercial property to pure possibility

We’re on a mission to turn unstructured data into actionable insight, helping our clients make better decisions and enjoy higher returns.

We started in commercial real estate in 2017, receiving a record amount of funding for a “proptech” company. Now, our advanced data modelling and machine learning capabilities have allowed us to take our learnings into other related sectors.
