Excerpt from an enterprise social software snapshot
One of the biggest providers of corporate social networks is Salesforce.com, the online business software company based in San Francisco. It said 80,000 companies use its corporate social network, Chatter, up from around 10,000 when it was introduced a year ago. Yammer, a start-up and also based in San Francisco, said its service is used by more than 100,000 companies, up from around 80,000 a year ago.
SAP, Cisco Systems, Socialtext, Jive Software and SuccessFactors are also pushing their products. Last month, VMware joined the list when it acquired Socialcast, one of the earlier networking services.
