Pricing shown is 'per Organization'. An Organization can represent any type of entity you want. For example, a business, a department, a team, an event - whatever you might need, it's up to you how you use them. They are provided to enable you to organize your surveys, customer feedback and reporting functions.
Each Organization can contain one or more survey templates, and one or more team members.
Organizations are tied to a pricing plan, where one Organization can utilise the free plan, it can be upgraded to a paid plan at any time.
Whilst you can have multiple organizations, one is all you need to get started. Add new organizations at any time you want.
