2015 Zimbra is acquired again. The new owner - Synacor


The open-source based email and messaging software provider Zimbra has been acquired by Synacor for $24.5 million. Synacor calls itself the multiscreen technology and monetization partner for video, internet and communications providers, device manufacturers and enterprises. Synacor officials said they will continue the open source version of Zimbra and provide technical support for Zimbra's Open Source Edition (OSE) through its VAR partners.

2013 VMware sold out Zimbra and SlideRocket



Probably, Aaron Levy was right. With the development of SaaS API technologies it's no longer profitable to buy all enterprise software from one vendor (and for vendors it's not profitable to build full enterprise stacks). For the last couple of years VMWare was trying to build (or rather buy) the own stack of enterprise software, and now it sells it out to focus on what they really do well - virtualization systems. In March VMWare sold online presentation service SlideRocket to ClearSlide (which specializes in sales apps) and today it sold Zimbra Collaboration Suite to the developer of enterprise community-building solutions - Telligent. Recall, WMWare bought Zimbra from Yahoo! in 2010. The video above shows how VMWare was inspired by Zimbra few months ago.

In addition, the company has recently bought Springsource to create its own web platform - an alternative to Google App Engine. The most popular open-source collaboration suite Zimbra will let VMWare to enter the Web-applications market. There’s no word on the sale price yet, but it's probably lower than the $350 million paid by Yahoo in 2006.
