Rather than deleting your personal PubNub account, you can simply create a new account with an alias email like: pubnub@mycompany.com - the actual email can be whatever you prefer.
From that "company" PubNub account you can share access with other individual PubNub accounts with various permissions.
Optionally, you can just change the email of your personal PubNub account to be the company alias email mentioned above and then create a new personal PubNub account for yourself.
If you need to transfer Apps or Key Sets from your personal PubNub account to the new account, contact PubNub Support and we can assist with that task.
