Isaac Mangrum was just hanging out with a friend when he looked over his buddy's shoulder and saw him scrolling through an app filled with jobs. Mangrum had already been driving for Uber and Postmates in his spare time just to get through college. The list of jobs he saw as his friend scrolled through the app had similar flexibility where he could work in his spare time, but paid a guaranteed hourly wage. "As I saw the app, I began to put it all together. You’re looking through jobs and you look for jobs you want," Mangrum said. "You'd have total control over what you'd accept."
