Microsoft co-founder Paul Allen is working on a new project called Xiant.  Xiant is an e-mail startup that makes using Microsoft Outlook much easier.  Xiant Filer allows users to make message filing much easier.  There is no need to change around Microsoft Outlook to make Filer work.  It integrates quite well within Microsoft Outlook.

There is a one click interface with Xiant Filer for filing messages.  There is also batch filing which allows users to move batches of individual messages.

Working on Xiant may help Allen forget about all the money he lost through his investment with Charter Communications.  Allen invested $7 billion for a 52% stake in Charter, but sold nearly all of his Class A common stock holdings for $996 million last week according to PeHUB.

Xiant is available as a free 60 day trial download from their website.

One of Xiant’s biggest competitors is Y-Combinator startup Xobni.  Xobni has about $14.6 million in funding between Y-Combinator, several VC firms, Cisco, the BlackBerry Partners fund, and several private investors.  However Allen is worth about $10.5 billion as of this year.
