I have a fairly used mobile app that I want to sell. Where do I start? Who do I approach? How do other people sell their companies? Do they just wait until someone approaches them or do they contact companies to see if they'd be interested?
Use Apptopia -- they're a marketplace for selling ownership of apps, like Flippa is for websites. Using a marketplace gives you access to audience of people who you know are interested in buying, and a process that protects the buyer and you both.
