Xobni ("inbox" spelled backwards) is a San Francisco-based startup, created in 2006. We make your inbox and address book smarter by making it easy to search and discover all your contacts - even those who aren't in your address book.
Xobni, Smartr Inbox, and Smartr Contacts automatically find all the people with whom you've ever exchanged emails, calls, or SMS messages. They instantly provide a full view of each contact, complete with their photo, job title, company details, and email history — as well as updates from Facebook and Twitter.
Xobni is available for Outlook. Smartr Inbox is available for Gmail. Smartr Contacts is available for Android and iPhone.
Xobni has raised three rounds of funding from leading investors including: Khosla Ventures, First Round Capital, Cisco, BlackBerry Partners Fund, Atomico Investments, Baseline Ventures, and RRE Ventures, as well as several angel investors.
