My team have been customers for a few months now. We love Archbee, and rely on it every day for all kinds of internal docs - server documentation, induction, sales call notes, special pricing, reusable marketing snippets, customer onboarding todos...
Originally we tried adopted it for product docs for customers. But then we realised it was a great solution to replace our internal docs as well. Specifically we replaced our internal wiki, Simplenote shared notes, and a directory of shared markdown files, with Archbee.
It's very intuitive, as demonstrated by the fact everyone in our team of 5 came to use it voluntarily, without any training or intro at all.
