Our Story

We Discovered The Problem

Despite being one of America’s largest industries, individuals that work on any asset outside the single family home have been deprived of insights and opportunities due to the fragmented, disparate nature of real estate information.

Most data is recorded in a variety of ways without a property identifier to make information shareable. We set out to fix this.

We Experimented Repeatedly

Our research and development team is comprised of industry experts who are masters in contemporary data and computer science. Using proprietary algorithms and machine learning, we not only provide the most up-to-date and accurate CRE data in the marketplace, but also uncover data that’s available nowhere else.

The Solution

Data Network

We’re bringing together the titans of data and leaders in commercial real estate by analyzing millions of records to provide the most robust records for every commercial property & owner.

AI: Machine Learning

Your key to linking commercial real estate data. We use advanced machine learning algorithms to analyze records, and map them to the Reonomy ID, a universal identifier for every commercial asset in the U.S.

Our Leadership

Reonomy’s CRE industry veterans, data scientists, and designers believe technology should do the hard work for you. We built the Reonomy platform to deliver commercial real estate intelligence that’s comprehensive, correct, and valuable to you more quickly and easily than you ever thought possible.
