AI Summary
5 min readIn 83 days, Brian Shin and his girlfriend grew a simple mobile app called ONES from zero to $22,000 in monthly revenue. ONES is a digital disposable camera for events—weddings, birthday parties, corporate gatherings—where guests capture candid photos into a shared album that reveals itself on a set date. But the most instructive part of the story is not the revenue number or the app itself.
