Yes, you can. There is no limit on the number of Space organizations one customer or company can have, so you can definitely create multiple organizations for different departments or teams in your company if you need to. You can’t combine users on different subscription plans within the same Space organization, however.
Even though it is possible to create multiple Space organizations, we believe that your company will be able to accomplish much more with a single unified one, as your employees from different teams will be able to communicate and collaborate together in a unified environment.
You can also create as many Free organizations as you need for testing, or purchase different subscription plans for different organizations, but please note that the owner email for each organization has to be unique.
