Rapportive officially bought by LinkedIn

Contacts startup Rapportive has been acquired by LinkedIn (s LNKD), according to a post on Rapportive’s blog Wednesday. The official announcement comes a few weeks after rumors of such a buy were first reported by AllThingsD.

According to Rapportive founder Rahul Vohra, the company will continue to support its Gmail plugin (s GOOG), which enables users to get more detailed information about people who have emailed them. That includes social connections such as LinkedIn, Facebook and Twitter, as well as their address books. The acquisition will no doubt lead to more integration with LinkedIn’s core properties, which could bring even more information about your work contacts into the fold.

AllThingsD reports that the price came in at the low teens of millions of dollars, with LinkedIn beating out other potential buyers, including Twitter. Rapportive had raised about $1 million in 2010, with investors that included Charles River Ventures, Dave McClure, Paul Buchheit, Jason Calacanis, Gary Vaynerchuk, Shervin Pishevar and Venture Hacks.
