Jack is a serial entrepreneur who has started two companies — Twitter and Square — that, on the surface, seem entirely different. Twitter is a social networking service; Square is a mobile payments company. But Jack believes that their shared purpose is to make each of their related tasks —communicating and transacting — easier. Twitter gets messages from point A to point B just as Square gets money from point A to point B.
