Yahoo on Wednesday continued a months-long take-over binge with word that it had bought Xobni, a startup behind tools for better managing contact lists and email inboxes.
Yahoo did not disclose how much it paid for Xobni, which is 'inbox' spelled backwards, but said it planned to use the startup's technology to improve Yahoo! Mail, Messenger and other "communications offerings."
San Francisco-based Xobni was launched in 2006, and two years later the venture-backed firm hired Yahoo executive Jeff Bonforte as chief.
A message posted at the Xobni blog on Wednesday indicated that the team was settling in to new digs at Yahoo's main campus in the Silicon Valley city of Sunnyvale.
"This is just the type of gig we've been preparing for throughout our history," Xobni said.
"Soon, you'll be able to use Yahoo! products with Xobni goodness baked right in."
Xobni products help manage email and other communications based on patterns of exchanges between people and their contacts.
