I can imagine it's hard to get this kind of info, it's not that cap tables are public and sometimes they don't even exist at all, especially if there's no investors involved.

Another data point would be the registered officer(s)/manager(s) with the secretary of state, but removing himself from it would achieve the same without having to change the company name, unless he then started a company with the same name?

But yeah, I also can't see how changing a name is hiding involvement...
