Professional networking site LinkedIn announced its acquisition of ChoiceVendor, which provides ratings and reviews of business-to-business service providers. Financial terms of the transaction were not revealed.

ChoiceVendor is based in San Francisco and was founded by CEO Yan-David Erlich, formerly an entrepreneur in residence at Battery Ventures and founder and CEO of Mogad/Social.IM, and vice president of engineering and former Google engineer Rama Ranganath, both of whom will join LinkedIn.

The ChoiceVendor site has already been shuttered, displaying this message from Erlich and Ranganath:

Today, LinkedIn announced that it has completed its acquisition of ChoiceVendor.

The ChoiceVendor and LinkedIn teams are equally passionate about helping professionals make the best decisions. As part of LinkedIn, we’ll contribute our knowledge and ideas to the products and services that reach LinkedIn’s network of more than 75 million professionals.

Effective immediately, we’ll be ceasing operations at choicevendor.com. We’re very grateful for your support, and we look forward to connecting with you on LinkedIn!

LinkedIn CEO Jeff Weiner said:

Our acquisition of ChoiceVendor is right in line with our top priority to build a world-class team at LinkedIn. We’ve admired the work that Yan-David, Rama, and the talented ChoiceVendor team have done for some time now and are excited to have them join us, especially given their highly relevant work experience.

Ranganath added:

Since Yan-David and I worked with members of the LinkedIn team in the past during our time at Google, we’ve kept a sharp eye on the company’s phenomenal growth. We’re excited about the direction that LinkedIn is headed, particularly in terms of helping its members derive valuable business insights from the site, and are looking forward to joining the team.
