In case you haven’t noticed, it’s impossible to find mobile developers. People ask me all the time if I “know anyone”, and I’ve all but given up helping with referrals.
The reason is “self-publishing” is now a reasonable option. The app store ecosystem has removed most friction from the system, provided a clean and easy business model (70/30 revenue split), and eliminated almost all barriers to entry. If you have talent, a laptop, and a coffee shop wifi connection, you have a chance at writing the next great app hit.
As a result, many good developers have (or believe they have) a better chance at doing their own thing vs working for someone else for salary or an hourly rate.
