A: Hello GFrancesco,

In caisy, each organization can support multiple tenants, not just each project. With the AppSumo T3 deal, you get 20 Projects. However, the number of tenants you can have is much more flexible. If you need to manage more tenants, you can easily acquire more through our self-service billing option, or you can get in touch with our team for a custom solution. To give you some perspective, we have clients who manage well over 1000 tenants using our system.

To get a better understanding of how our system is structured and how you can manage multiple tenants, I'd recommend checking out our guide on the relationship between organizations, groups, and projects: Organizations, Groups, and Projects Guide:

Hope that helps :)
