"Building a good app, getting a good user base ... and then they can sell it to someone who knows how to monetize it," he says.
There are other possibilities provided by a thriving secondary market in mobile apps, according to Ty Rollin, CTO of business mobility specialist Mobiquity.
"The cool thing about this model is the analytics collected could help inform the value of an app before a developer even builds it. We're not sure how big this is yet, but like any secondary market, if there are arbitrage opportunities, people will find them!" he said in an email.
Kay admits, however, that the secondary market doesn't see a lot of businesses seeking out apps for internal use.
"Most companies that are big enough to need an internal app ... work with another really, really big company that specializes in internal catalogs," he says.
That said, it doesn't need to be the case, according to Rollin.
"These marketplaces would be ... good, as long as they have (or will have) a process in place to certify these apps for enterprise use, both at the code and executable levels," he said.
