Yes, I think it is, although I see a few challenges. It is a huge amount of work to integrate disparate data sets and build a system that can efficiently handle many customers' requests. It may be difficult to show customers how they can actually use it. Comparing two stocks isn't cool. You know what's cool? Comparing all stocks with realtime updates. For the second problem, I mean that users won't use their imagination much to figure out what your product does. You have to spell it out in concrete, actually useful examples. This is a challenge between engineer-thinking, where general functionality is king, and user-thinking, where one particular goal and the path of least thinking/work is king.
