You can once again create organizations manually on events using our latest Registration Form Builder. Head to the Organizations page in your event and you'll find "Add new organization" button back where it belongs!

When creating an organization, you can assign an owner from your participants — the only restriction is that participants who already own another organization can't be assigned again. And if the owner isn't known yet, no problem: just create the organization for the relevant participant type, and link the owner whenever you're ready.

The organization creation form follows the fields you've configured in your registration form, so it stays consistent with how your participants would fill it in themselves.
