No, currently, your subscription on Brevio can only have one user linked to an organisation. Sharing a subscription between multiple organisations or setting permission levels for different users is not available at the moment.
However, Brevio has plans to provide team access in the future. This means that there will be an option to have multiple users attached to the same organisation under a single subscription. This feature will allow teams within an organisation to collaborate and access the platform together. Keep an eye out for updates from Brevio regarding the availability of team access and multiple user functionality in the future.
