During his sophomore year, Kushner was founding executive editor of Scene, a new Brooks Brothers-sponsored student-publication that aimed to be "Harvard's version of Vogue and Vanity Fair". According to The Harvard Crimson, Scene "faced blistering criticism upon its release", with students going so far as creating a "Scene Magazine is Bullshit" Facebook group criticizing it for its "completely ludicrous... skewed portrayal of the Harvard community" and "lack of models who were minorities". In the spring of his junior year, with two graduate students he pooled $10,000 to found social network Vostu, which aimed to "fill a void left by online communities in which English is the lingua franca", like Facebook. According to Kushner, Latin America was a promising market for a Facebook-alternative and new social networking site because " a place where Internet use is increasing every year, and technology is booming at a rapid pace". The year after graduation, he also co-founded a start-up called Unithrive, with the cousin of the president of Kiva who was also a Harvard student. Unithrive was inspired by the peer-to-peer loan model of Kiva, but aimed to "ease the crisis in paying for college" by matching "alumni lenders to cash-strapped students... who post photographs and biographical information and request up to $2,000", interest-free for repayment within five years of graduation.
