“my name's Ethan and I built a mobile app that makes me 20 000 per month I launched it in September and over the last six months we've gone from 0 to over 60 000 total revenue”
Editor's note: He dropped out of college to build apps. Revenue followed the wrestling season, when demand for weight cuts peaks.
