About
Xobni (inbox spelled backwards) was a San Francisco-based software company that developed an email search and contact management plugin for Microsoft Outlook, later expanding to mobile applications. The platform indexed a user's full email history and automatically surfaced rich contact profiles — including communication frequency, shared contacts, and attachments — directly within the Outlook sidebar, enabling faster search and smarter relationship management. Xobni's Smartr product suite extended this capability to mobile devices, discovering all contacts across email, phone calls, and SMS. Founded in 2006 as a Y Combinator company, Xobni raised over $30 million in venture funding before being acquired by Yahoo in July 2013.
