ABOUT US

We are digitizing the world's real estate, empowering all people to discover properties, insights, and connections that improve their businesses and lives.

Since 1987, our work has kept the customer at the center of all we do. Clients, brokers, business buyers and sellers, and people looking for their next place to live depend on our information to make informed business decisions and plans for their future. Named to the NASDAQ 100 Index and S&P 500 Index for our leadership in real estate and technology, we are the industry standard because we’ve created, refined, and perfected a language that an entire industry trusts.
 
We continue that effort today and are always working to improve our information and analytics.

This is how we deliver for our customers, our employees, and investors. By equipping the brightest minds with the best resources available, we provide an invaluable edge in commercial real estate.
