Is this mac only? Are there plans for PC, Desktop, apps? The website /feels/ very mac-centric which is why I am assuming and that feels like a disastrous mistake if its the case.
(I work at Quill.) We're on all platforms! Can't have a team chat app unless the entire team is able to use it :)
Throw this under the 'Professional Messaging' with something like 'Cross Platform': 'Works on all your favorite tools - your browser, Mac, Windows, Android, and iOS.'
Otherwise, this just feels like an apple garden app.
