To me, the question is, can you build a better software team than your current product provider has? If you are planning to hire developers as if they are just construction workers, you're in for a bad surprise. Plus, attracting talent to such an industry would be very hard unless you are willing to pay high amounts, often with equity.
If you're going to hire one guy to start, check their portfolio to see that have build apps from scratch, and evaluate the quality. Many can't ship.
In my experience most folks stay at a company because of the relationships they form, not necessarily because of the work.
If you have a team of great people with an awesome attitude and human leadership, you could be doing almost anything (tech wise) and be happy.
The best technologists tend to follow each other around, if you have an exceptional leader, folks will follow them to the company, regardless of the business domain.
