Find something, figure out some way to require an internet connection and subscription fee to use that thing, then sell that thing as a service.
Tire pressure as a service. Coffee cup as a service. Toilet as a service. Locks, mail, trash, we'll have a guy come by and tie your shoes for you - no scratch that, Uber for shoes. Doesn't matter what it is, as long as you convince people that having you and your app do it for them is simply better.
