We're sharing a special preview of the new podcast, What’s Your Problem? from Pushkin Industries. What’s Your Problem? explains the problems really smart people are trying to solve right now, from creating a drone delivery service to building a car that can truly drive itself. Jacob Goldstein, former host of Planet Money, talks with innovators about the future they’re trying to build – and the problems they have to solve to get there. In this preview, Jacob talks with Katherine Sizov, founder of Strella Biotechnology. Her problem: Tons of food is wasted before it ever gets to the consumer. Katherine started working on this problem in 2018, when she was a junior in college. Her idea: imitate the natural world and build a device that detects when fruit is ripening. It worked. Now some of the biggest apple and pear packers in America use her device. You can hear more from What’s Your Problem? At podcasts.pushkin.fm/wypheat.
