Bummer to see so much jeering in the comments here. No iteration of this product will be compelling to the "not interacting with people is the best part of remote work" crowd, but they aren't your market. However, I think you might be able to land on something that addresses the privacy concerns while still improving on "in the room"-like serendipity for remote teams.
I've worked on a team that used Mumble audio-chat years ago. Everyone kept it on much of the day with a global push-to-talk key, and it was mostly quiet but super helpful for spontaneous conversations. It's basically like using walkie-talkies, now that I think about it. I wonder if something like that would be compelling here (e.g. I can pop up on your screen on-demand, but I won't see you unless you acknowledge).
Anyway, congrats on the launch. Look forward to seeing where this goes!
