CK Prahalad developed the bottom of the pyramid (BOP) theory which proposes that large corporations can profitably serve the world's poorest populations. The BOP includes 4 billion low-income consumers representing potential opportunities for businesses to meet needs, increase productivity and incomes, and bring more into the formal economy. Prahalad argued that firms must rethink their strategies to develop affordable products tailored to BOP consumers through approaches like small packaging, low margins, and alternative distribution networks. Some companies have found success adopting BOP strategies in sectors like mobile phones, consumer goods, and financial services. However, critics argue it can be very difficult for companies to successfully serve BOP markets without a deep understanding of local consumer behaviors and needs
