Despite of the adverse economic climate and the fact that Xobni is a free plug-in for a commercial product like Microsoft Outlook, the two-year old San Francisco based startup has another reason to celebrate the new year after receiving $7 million in Series B financing.

Personally, ever since I discovered Xobni I have never looked back and if you rely on Outlook for managing your email you shouldn't hesitate to at least give it a try (in case you didn't notice Xobni stands for "inbox" spelled backwards).

According to the developers, Xobni has been downloaded 1.5 million times since the first public release last year and they are now working with large corporations to show the benefits of the product under those environments. The company plans to release a paid version eventually that extends functionality beyond what is currently offered.
