Social intrapreneurs are people who work inside large organisations to develop and promote practical solutions to social or environmental challenges. Social intrapreneurs apply the principles of social entrepreneurship inside a major organisation. They can also be characterised by an ‘insider-outsider’ mindset and approach. One example is Win Sakdinan at Proctor & Gamble who developed the company’s Future Friendly initiative, which helps consumers to save energy, water and packaging with its brands. Another example is the nurses as social entrepreneurs programme developed at Oxford University’s Saïd Business School.
