Hello,
I don’t know plugins to recommend for this use case.
Look if you may use the URE Pro add-on, if it is suitable:
1) Content view restrictions – if company listing profile is a separate page and changes are made via front-end.
2) Posts/Pages edit restrictions – if company listing profile is a separate page and is edited via back-end at the page editor.
3) Other roles access add-on.
If you can setup the list of user roles for your needs, user limited via “Other roles access” can grant only roles available for him and see users with this roles list only.
