Zimbra, Inc.

Zimbra is the leader in open source, next-generation collaboration and messaging software. We provide innovative experiences to end-users and their administrators because we see existing tools are fundamentally broken. We also believe in compatibility with existing infrastructure and applications (both open source and proprietary). Thus our solutions are cross-platform: including Linux and Mac OS X on the server-side; Windows, Linux and Mac on the desktop; and Firefox, Safari and Internet Explorer browsers.
