Can I delete my "personal" account, so my company is the only organization I'm in?

I’d ideally like to remove the “organization” that’s just associated with my login – I only created an account so I could admin my company’s typeform. Is this possible?If not, is there any way to make my company’s organization the default, so I don’t have to manually change?

Also, is the API key I generated in the settings menu for my (useless) personal organization, or for the organization I had selected before clicking settings? It’s not clear at all if the settings for organizations are separate.
