I love proton and am a paid user, but I'm not sure if it has all the features a business needs. I'm personally waiting for a calendar before dumping google altogether (except for spam / email lists). Still, it seems better than anything else out there as far as privacy, though I would never count on email privacy to begin with for obvious reasons (unless I encrypt it myself / have others send encrypted email).
