Yammer

edit

Yammer is an enterprise social network, providing a secure way for employees to communicate, collaborate, and share information.

The company was founded by David Sacks formerly the COO of PayPal. Yammer grew out of the genealogy app Geni as a way for organizations to communicate.

Employees using Yammer can discuss ideas, post news, ask questions, and share links and other information. Yammer also serves as a company directory in which every employee has a profile and as a knowledge base where past conversations can be easily accessed and referenced.

Anyone in a company can start their Yammer network and begin inviting colleagues. The privacy of each network is ensured by limiting access to those with a valid company email address. The basic Yammer service is free. Companies can pay to claim and administer their networks.
