An intrapreneur is an internal entrepreneur - someone who operates within a large company to get things done, often by unconventional means. Someone who sees corporate pain and works out how to fix it, not by a massive reorganisation or a CEO directive, but by working with people at all levels within the organisation and making things happen. Someone who is not content to just come in for eight hours a day and go home, but who wants to make a real difference. Someone like me :)
