Did you get this one figured out? You should be able to switch the view from Contacts to Companies, and then export what you have in your filter. We have some documentation on it here: https://knowledge.hubspot.com/articles/kcs_article/contacts/export-contacts-companies-deals-or-ticke.... Is that what you're trying to do and it's not working?
Let me know if you have any questions and I'll be happy to look.
