IBM has entered the enterprise email market with the launch of IBM Verse, a service the company claims gives enterprise customers, small businesses, and individuals a scalable, social collaboration tool that lives on the cloud and is optimized for mobile and web environments. Verse combines the various ways employees connect each day, including email, meetings, calendars, file sharing, instant messaging, social updates, video chats, and more, and is the first messaging system to feature ‘faceted search’, a technique that lets users pinpoint and retrieve specific information they’re seeking across all the various types of content within their email.
