For reasons of confidentiality, I would prefer not to do so. Furthermore, implementing something like this is not yet a high priority.

There are some information services that offer global zip data, sometimes even as open source. Of course, we could combine this ourselves with other data sources on demographics, income or purchasing power. However, if something like this were available from a single source, it would naturally be easier to implement.

If you want to start a business with something like this, I would reckon that it might be hard to get started, because of the already existing competition, but it might become easier the more datasets you were able to integrate. -- Perhaps you should go deep first instead of broad. Something like starting with a single state and integrating all sort of data sources and then expand from there.
