Jim McKelvey wanted to build electric cars, but his friend Jack Dorsey said he didn’t know anything about building cars. So, the two entrepreneurs decided to work on a software project….after many ideas, rejected or abandoned, they came up with what looks like a simple device called “Square.” It’s simply revolutionizing the way commerce works.

McKelvey shares the backstory on Square’s creation with MBA’14, Kasey Joyce in this segment of an interview recorded recently when Jim was on campus to talk to students in the Entrepreneurship and Venture Capital Platform.
