One prominent customer of Socialcast is SAS Institute (see SAS's Year of Living Socially), which has branded its social network for employees The Hub. This private labeling of the enterprise social network means many users of The Hub have never heard of Socialcast--to them, The Hub is just The Hub.
SAS employees say one reason The Hub has become valuable is it allows them to connect with other employees with similar interests from around the company, and discover new contacts through existing contacts. Because SAS is a global company, this greatly expands the pool of people they can collaborate with, rather than being limited to contacts in their local office.
SAS has also integrated The Hub into corporate communications, for example by using it to solicit questions for the CEO prior to a Town Hall webcast.
