The document discusses the "bottom of the pyramid", which refers to the largest but poorest socio-economic group consisting of approximately 2.7 billion people living on less than $2.50 a day globally. Management scholar CK Prahalad introduced this population as a potentially profitable consumer base in his 2004 book. Products tailored for bottom of the pyramid markets with very low prices and small packaging sizes can be revenue generating. Targeting the needs of the bottom of the pyramid is important because profitable businesses serving their needs have a better chance of scaling their social impact compared to social projects.
