"Startup" and "entrepreneur" have recently become buzzwords in the lexicon of American culture. Most people associate these terms with the latest Internet and mobile technology companies. They think of people like Mark Zuckerberg of Facebook, Jack Dorsey of Twitter (and more recently Square), Dennis Crowley of Foursquare, etc. However, these terms really describe a particular approach to business, not any specific industry type. Any retail store, service provider, or small business can fit the bill if they're in the right mindset.
