The Xobni celebrates the move to Yahoo.
Yahoo has continued its takeover binge with word that it has bought Xobni, a start-up behind tools for better managing contact lists and email inboxes, for a reported $US30 million.
Yahoo did not disclose how much it paid for Xobni, which is 'inbox' spelled backwards, but said it planned to use the start-up's technology to improve Yahoo Mail, Messenger and other "communications offerings".
Technology blog AllThingsD pegged the deal at between $US30 million ($32.9 million) to $US40 million, citing numerous sources. Yahoo said that 31 Xobni employees will be joining Yahoo, including chief executive officer Jeff Bonforte, who previously worked at Yahoo.

Prior to being acquired by Yahoo, the start-up had already raised at least $US30 million in investment from Khosla Ventures and others, according to tech news website Gigaom. Microsoft chairman Bill Gates had also demonstrated it on a stage, saying it added value to Outlook.
In 2009 Microsoft took Xobni under its wing in its BizSpark accelerator program, but did not purchase the company. Outlook 2010 was launched with a similar feature, Social Connectors, that pulled contacs' social networking feeds to the email program. Co-founder Adam Smith declined to comment on any financial arrangements between the two companies at the time.
San Francisco-based Xobni was launched in a Cambridge, Massachusetts dorm room in 2006 by Smith, now 28, and Matt Brezina, 32, as part of the prestigious Y Combinator start-up program, and two years later the venture-backed firm hired Yahoo executive Jeff Bonforte as chief. In 2010 co-founder Smith left the company but remains a board member.

A message posted at the Xobni blog on Wednesday indicated that the team was settling into 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.
The acquisition continues a shopping spree launched after Marissa Mayer became chief of Yahoo a year ago.
