Intrapreneurship: the act of behaving like an entrepreneur while working within a large organization. “A person within a large corporation who takes direct responsibility for turning an idea into a profitable finished product through assertive risk-taking and innovation”. Intrapreneurship is now known as the practice of a corporate management style that integrates risk-taking and innovation approaches, as well as the reward and motivational techniques, that are more traditionally thought of as being the province of entrepreneurship.
This definition is directly taken from wikipedia, sometimes it’s safer to become an intrapreneur than an entrepreneur, there’s less risk involved, but sometimes less profit also. You need to decide which sounds more appealing to you.
