The story

LoopNet was founded in 1995 by Dennis DeAndre. Working alongside engineer Steve Midgley, the two built LoopNet into the internet's largest commercial real estate listing service. LoopNet underwent three rounds of private venture capital financing in 1997 (Indo Suez), 1998 (Trinity Capital & Partners) and $20 million in 1999 from fourT5 real estate brokers.

LoopNet was an early venture in Internet-based user-created content. As early as October 1996 virtually all of its commercial property listings were being entered by its users directly. Over time, LoopNet added the capability to import listings in an automated manner.

In 2001, the company merged with PropertyFirst.com.

In June 2006, the company became a public company via an initial public offering. At that time, the company had 360,000 commercial properties for sale or lease.

LoopNet acquired BizBuySell (2004), CityFeet (2007), REApps (2008), Land & Farm/Lands of America (2008) and Bizquest (2010).

In April 2012, CoStar Group acquired LoopNet for approximately $860 million in cash and stock.

In 2014, the company settled a trademark infringement lawsuit that it brought against Dotloop.

In 2020, to address rapid changes occurring in the COVID-19 commercial real estate market, the company added significant virtual tour capabilities.

In 2022, LoopNet expanded its international presence by launching LoopNet.co.uk, migrating the UK commercial property portal Realla.co.uk into the LoopNet brand. This move established a dedicated platform for the UK market. In 2025, the company further extended its reach into Europe with the launch of LoopNet.es and LoopNet.fr, targeting the Spanish and French commercial real estate sector.

Controversies and legal

Legal issues

In CoStar Group, Inc. v. LoopNet, Inc. (2006), in which Loopnet prevailed, it was determined that Loopnet, as an operator of a website, was no different from Netcom, then an internet service provider, and was not responsible for copyright infringements by its users. This ruling established precedent for copyright liability protection for many websites. It followed the Religious Technology Center v. Netcom case (better known as Scientology vs. the Internet). LoopNet demonstrated that it policed any user violations after the fact. The court did not require the company to stop future violations before they occur. Such a ruling could have effectively shut down LoopNet's website as well as those of many application service providers. CoStar unsuccessfully argued that LoopNet was an active party to the violations and thereby guilty of copyright infringement.
