RealMassive, a burgeoning tech firm based in Austin looking to change the way commercial real estate transactions take place, has expanded its footprint by officially launching in Dallas, Fort Worth, Houston, San Antonio and San Francisco.

It is the first data provider to deliver open access to the commercial real estate marketplace. These five additional cities put RealMassive on track to exceed 2 billion square feet of commercial property coverage by the end of the year.

The website connects owners, brokers and prospective tenants of commercial real estate to help make the process of buying, selling and renting properties much easier. RealMassive promises that information is accurate and up-to-date in real time.

They accomplish this through partnerships with leading commercial real estate firms in each market they cover, as well as employing hundreds of researchers all over the country. According to a release, some of the more popular features include hosted real-time market surveys that enable property owners, brokers and tenants to collaborate throughout the search process; real-time notification when spaces come off the market; custom marketing channels; and a service that enables syndication to Twitter and other online channels.

The listings are broken down into categories such as flex space, industrial, land, medical office, office and retail. Once a city is selected, the results are displayed on an interactive map. Users can click through to get more information about the property — including square footage, price per square foot, year built and renovated, and floor plan — and add the listing to an online portfolio.

If the website is any indication, the company shows no signs of slowing down: There are 32 other cities listed, although RealMassive does not have a foothold in those markets yet.

Sites like Zillow and Trulia have done similar work for residential real estate firms and prospective homebuyers, but RealMassive is the first to provide this kind of service for commercial real estate.
