Yammer, Inc. is a freemium[2] enterprise social network service that was launched in 2008 and sold to Microsoft in 2012.[3][4]
Yammer is used for private communication within organizations or between organizational members and pre-designated groups, making it an example of enterprise social software. It originally launched as an enterprise microblogging service and now has applications on several different operating systems and devices.[citation needed] Access to a Yammer network is determined by a user's Internet domain, so only those with appropriate email addresses may join their respective networks.[citation needed]
History
On September 8, 2008, Yammer launched at the TechCrunch50 conference.[3]
In February 2010, the company launched "communities", which are networks for which access is not restricted by domain, thus allowing businesses to connect to groups such as customers, partners, and suppliers.[citation needed]
In April 2010, Yammer CEO David Sacks said that Yammer revenue was doubling every quarter, but would not disclose 2009 revenue beyond describing it as "seven figures." Sacks also said that 70 percent of Fortune 500 companies were using Yammer at that time.[5]
In September 2010, the service was being used by more than three million users and 80,000 companies worldwide, including 80 percent of the Fortune 500.[6] Also at this time, Yammer 2.0 was launched, and aimed at being a more fully featured social network for the enterprise.[6] The new version of Yammer is designed to be more than a communications platform and it has been described as a Facebook for business.[7]
Yammer also gives third party developers the opportunity to create and sell their collaboration applications directly to users of the platform.[6]
Yammer received $142 million in funding from venture capital firms Charles River Ventures, The Founders Fund, Emergence Capital Partners, Goldcrest Investments and angel investor Ron Conway.[8]
On June 25, 2012, Microsoft acquired Yammer for $1.2 billion.[9][10] The acquisition was completed on July 19, 2012.
