Xobni is a San Francisco, California based startup that is revolutionizing the way people manage email relationships. The name Xobni, which is the word "inbox" spelled backwards, is an affirmation of our mission: to "take back" the email inbox for our users.

We started Xobni because we believe that people spend too much time searching for conversations, attachments, and other important information in their inbox.

Xobni offers a new way to organize and search your Outlook email. Xobni creates profiles for each person that emails you. These profiles contain relationship statistics, contact information, social connections, threaded conversations, and shared attachments. Our users tell us that Xobni makes your inbox work the way your mind does.

Xobni was founded by Adam Smith and Matt Brezina in the spring of 2006 with seed funding from Y Combinator. Xobni is backed by great investors, including venture capital firms Khosla Ventures, First Round Capital, Atomico Investments, Baseline Ventures as well as several angel investors.
