Sure, we all use LinkedIn. But the professional social networking site sometimes lacks….a certain sense of personality, especially when it comes to referring your actual friends (and not just personal connections) for a job. YesGraph bridges that gap, using both Facebook and LinkedIn to help you identify your legitimate social connections – as well as your coworkers’ friend circles – when recruiting, making a hire, or making a trusted referral. The co-founders honed their recruiting chops at Dropbox, Facebook and Adobe, so they know a thing or two about finding the right people while maintaining a quickly-growing company’s sense of identity and culture.
