Isn't this often the case? Startup founders seeing a market they don't understand completely, then talking to customers and working towards a good solution? In fact, one of the problems today is that a lot of the best software is written for programmers/entrepreneurs or other markets which programmers know intimately. Writing software for markets that programmers don't know is done much less so (meaning there are tons of opportunities there).
