Entrepreneurs have disrupted nearly every industry, developing start-ups that transform the way business is done. Airbnb for example has changed the world of travel forever. Today, this company enjoys a value of more than $31 billion. Lyft comes in at a cool $7.5 billion, after turning the taxi service industry on its head. FinTech firms like Stripe have created mobile payment solutions that are used by leading financial services companies like Visa. Even specialized services such as computer security are dominated by disruptors like Synack.
