Today, more number of people are taking to entrepreneurship because the cost of starting a business is lower than what it was before. That said every successful start-up makes its mark only after it has successfully identified or created an opportunity and implemented it. For instance, Michael Dell, founder, Dell, found the opportunity in doing away with middlemen and started his own company that dealt directly with customers and built individual specific computers. He soon turned his fledging startup into a multibillion-dollar enterprise. Closer to home, MakeMyTrip started offering online airline ticketing based on fare comparison and option, which practically rung the death knell for travel agents.
