Nice, I worked on something similar during COVID but it was more about preparing and tracking needed discussions well enough that you don't have to have the meeting in the first place (company failed, open source code is at https://github.com/async-go/asyncgo). We found that, at least at that time, companies fell into two camps - they were already doing async well and writing things down and didn't need us, or they were just desperately waiting for COVID lockdowns to end so they could get people back into meeting rooms - they don't see it as a problem, had never seen it work any other way, and so we couldn't solve it for them.

If I can share anything or just talk through my experiences let me know. I think reducing time spent in nonsense meetings actually does make the world a better place for the humans in it, at least a little bit.
