There are a few options for sharing your Concerto-built models.
You can either save or move the models you wish to share, into the Team Drive. Other users or partner users added to the corporate entity that you are in, given they have the appropriate permissions, will then also be able to access your content.
Another simple way to share your documents and models involves exporting from within the Modeller. The containing file format of whatever you export will be a .json file, which you can share with other Concerto users to then import at their own discretion.
Note: The .json files you export do not carry over associated images used in the exported model/s, or, for security reasons, any transactional and operational data. If you wish to share the transactional or operational data of your models too, you can export all model data from within the Worksheet into an .xlsx file.
