The most prolific users of excel that I know of are:

1. Investment Banking Analysts 2. Researchers/Academics

In either case, I would try to find a smaller firm with a relationship to tech that could appreciate what you're trying to do.

I'm not sure I know what you're trying to do but based on "Identify which spreadsheets violate best practices" it sounds like you're trying to provide a better workflow for creating and maintaining large excel documents in the way that developers have version control and continuous integration. Ie. code climate, linters, testing, for example docs.

Sounds cool.
