In order to transfer the ownership of an organization to a different user, first make sure that that user is added as collaborator on the organization in question. Read more about that process here: How do I create and manage organizations?
Once the desired new Owner is a collaborator on the organization, the current Owner must email support@hologram.io from the email associated to the organization on the Hologram platform following the template below. Replace the <> tags with your request:
Subject
Account transfer
Body
Please permanently transfer Organization <ORGID> to user <new owner's email>.
I acknowledge that I will no longer be the owner of that organization or
the SIMs that are in it.
