We source all our opportunities from real people who've told us about a specific pain point they would pay to have solved.

This then acts as a pointer for us to explore further. Then we do a little more research and analysis about the problem space. If we think it's worthwhile, then we send it out.

To give you an example, to date we've gone through over 70 opportunities and of those we feel only 17 are good enough to send to customers.
