Keller Rinaudo

Every day, thousands of people die for lack of medical supplies, from vaccines to snakebite antivenom. In 2014, Keller Rinaudo began testing a solution: drones. Since then, the CEO and co-founder of California-based health startup Zipline has overseen the drone-enabled delivery of vital medical goods across Rwanda. The company’s battery-powered, fixed-wing “Zips” have covered more than 1.2 million miles and made over 23,000 emergency deliveries. Early next year, it will launch in the Indian state of Maharashtra. U.S. deliveries are not far behind, says Rinaudo: “If we’re going to have instant delivery for hamburgers, we should absolutely have instant delivery for medicine.” —Aryn Baker
