I recently wondered, what the business model of Stack Exchange is. As there were already several questions to this, I found a satisfying answer. But I'm often using the mobile application, and there are neither advertisements displayed, nor are there any job listings etc. shown. So I wondered, whether/how Stack Exchange makes any money/profit with their application.
Does Stack Exchange make any money with the mobile app?
No, at least not directly.
The apps are just part of the total user experience Stack Exchange provides, just like the mobile version of the sites, which don't have any ads either. The idea is that by making it easier to participate on Stack Exchange, you make the users more committed, which increases page views on the normal site which does show ads.
