Businesses are people, profit..but first of all purpose, says Bob Collymore. He has been CEO of the mobile phone company Safaricom in Kenya since 2010. It is the company that introduced mobile money to Africa 10 years ago, under the brand name M-Pesa. What was designed as a send-money-home service for people living far from their villages has developed into a vital arm of the economy, adding microloans for solar power and micro savings for healthcare to its range of services. Bob Collymore explains what inclusive prosperity means–and might mean–in Africa.
