10 technologies for the bottom of the pyramid

» more from Tech Edge

The bottom of the financial pyramid, a term reportedly coined by U.S. President Franklin Roosevelt in 1932, refers to the world's lowest income-level group, one that spans more than 4 billion people worldwide.

Many experts believe these individuals should be given a chance to participate in the global economy as both consumers and entrepreneurs. In his book 'The Fortune at the Bottom of the Pyramid,' University of Michigan professor C. K. Prahalad discusses business models that have tapped into this group by developing market-specific products with the needs of the poor in mind.

BoP Hub, a Singapore-based non-profit venture, engages in Prahalad's philosophy by helping social enterprises form partnerships with the private sector to create a niche marketplace for the poor.

"Through job creation and enterprise development, poor communities gain access to income-generating opportunities; their economic participation in the formal economy greatly improves their livelihoods and helps to break the endemic cycle of poverty," said Divya Chandran, BoP Hub's communications manager.

In this slideshow, we bring you 10 innovative technologies that cater to the base of the pyramid. While many of these products remain out of reach price-wise for the majority of individuals, most can be purchased by governments or non-profit organizations and distributed through communities.
