In September 2011, Princeton student Josh Miller and NYU student Hursh Agrawal each took a leave of absence from their universities and teamed up with Cemre Güngör to found a company called Roundtable. The trio bootstrapped the company from New York City for four months, eventually moving to San Francisco in January 2012 to build the product with guidance from Obvious Corp.’s Evan Williams, Biz Stone and Jason Goldman. In May, the company — now called Branch — returned to New York City and is currently a team of eight, whose mission is to empower people to talk about the world around them.
