How Zipline Helps Remote Regions Get Blood From a Drone

Keller Rinaudo began his career as the cocreator of Romo, a tiny toy robot. But for the past five years his work has been, well, bloodier. His company, Zipline, uses autonomous planes to deliver medical supplies--vaccines, pharmaceuticals, and blood--to hard-to-reach places. It signed its first client, the government of Rwanda, in 2016, and says it now fulfills about a fifth of the blood needs of the country's rural population. Anne Wojcicki, cofounder and CEO of 23andMe, says she was drawn to Rinaudo's "passion, dedication, and laser focus on what he wanted to accomplish."
