"Just landed in Nairobi! I'm here to meet with entrepreneurs and developers, and to learn about mobile money -- where Kenya is the world leader.
"I'm starting at a place called iHub, where entrepreneurs can build and prototype their ideas. Two of the engineers I met -- Fausto and Mark -- designed a system to help people use mobile payments to buy small amounts of cooking gas, which is a lot safer and better for the environment than charcoal or kerosene. It's inspiring to see how engineers here are using mobile money to build businesses and help their community."
