In India around one fifth of the population still live below the poverty line, according to the most recent World Bank estimates. Businesses selling to this market need to keep prices low. In the famous tech city of Bengaluru, south India, we visit a veterinary clinic for pets, the unlikely home of a surprising young start-up, which is set to revolutionise one of the most common medical devices on the planet – the stethoscope. In a village in Mathura, about three hours drive from New Delhi we take a look at the installation of a new affordable solution to providing solar energy. We then meet a young entrepreneur in Kenya who is looking at the success of firms like Amazon and has developed his own similar internet based delivery system for Kenya’s low-income customers.
