I've bought 40-50 Android and iOS apps, mostly made by individuals and microcompanies - I think some people might consider them startups, others would not. Does a company have to have grand plans to be called a startup? I've done business with startups like Etsy from when they were in the startup stage, to the established business stage (Etsy still considers themselves a startup though, however I think a company has passed that stage 6 years and 150 employees in). I've hosted sites on Heroku, bought 'pro' on Forrst, and booked a flight through hipmunk. It seems there are probably some other companies in there, less well known, but it's not coming to mind.
