Yes, it is possible. We set it up for you on the platform so there is access to the parent company and the sister(s) company on the same platform. The companies are set up in a hierarchy where the main org. is at the top and one or several sub-orgs are nested under (see picture below).
This means you are able to have separate surveys and view your data separately for each company. You are also able to compare your scores between the different organizations.
