Linkedin buys online talent and recruiting platform Careerify

Careerify's CEO admitted LinkedIn offered something his company couldn't do on its own.

LinkedIn has been steadily scaling its digital publishing ambitions, but the tide is turning back toward its job connection core with the acquisition of Careerify.

Founded in 2009, the Toronto-based startup comes with its online recruiting and talent acquisition platform, which supports management for employee referrals and internal job mobility.

Some of Careerify's more prominent clients to-date include Microsoft, Deloitte, and Groupon, among others.

Financial terms of the deal have not been disclosed.

Careerify CEO and founder Harpaul Sambhi confirmed the merger in a blog post on Monday, admitting LinkedIn offered something Careerify couldn't do on its own.

Quite simply, that is to grow (successfully) as "massive scale."

"We started this business during one of the worst recessions of our time, where the term 'needle in a haystack' reflected the job search experience for millions of candidates," explained Sambhi. "In response, we developed a referral solution that looked at open jobs within an organization and scanned its employees' connections on social networks in real-time to pinpoint the perfect candidate."

Careerify will continue to serve existing customers and provide support for employee referral software.

However, it will no longer accept new customers as it transitions toward implementing its technology into the LinkedIn infrastructure.
