What's the easiest way to rename your company in the app store?
Renaming your company is a paperwork-intensive process - you need to provide proof to Apple that the new name is registered as a company and owned by you.

Thanks for the link. How does company/organization name work when one doesn't have an LLC or anything else "official"? Perhaps one can just use their name.
