The New Money

摘要

Square, founded by the creator of Twitter, lets people accept credit cards with their smart phones. That innovation could transform transactions in surprising ways. In Silicon Valley, every serious startup has a founders' story. In Christmas of 2008, Jack Dorsey, the creator and chairman of Twitter, was visiting his parents in St. Louis. At the time, he was at loose ends. Twitter had five million users, but in October he had been replaced as chief executive by his better-known cofounder Evan Williams, who, rich from the sale of an earlier company to Google, had funded the original development of the communications network. Dorsey was wondering what he should do next. He felt it should be something big and complex. The economy was in a recession, but that was the best time to begin a new venture, he believed. "Everything has been cleared away and you can start fresh," he explains.
