It's okay to have a "company" that doesn't use the indie faction set up as long as it remains a local-level business. However, if that "company/corporation" grows to the size in which it begins affect significant regions around it, it will need an indie faction app in order to continue. If there is any doubt, feel free to PM the details to me.You can either do a made-up corporation for your designs in the technology subforum, or you can do an Independent corporation. If you go with option A, I don't believe it's permissible for it to grant you extraordinary wealth or access to banned equipment. If you go with option B, you'll need 2 other people to join, and meet other Indie group requirements.
