In his book “Screw the Valley,” author Tim Sprinkle takes on Silicon Valley’s place at the top of the tech totem pole and suggests seven other cities that offer as-good or even better environments for building tech businesses: New York, Boulder, Raleigh, Detroit, Las Vegas, Kansas City and, of course, Austin. At a Texas CEO event in Austin, sponsored by Khorus, Sprinkle spoke to the crowd and participated in a discussion with Khorus CEO and fellow author Joel Trammell.
