For a meeting scheduler site? I feel like you're overestimating the capabilities of something that is akin to college graduate project.

This company does not seem healthy at all:

I agree with the other poster that mention this is likely a publicity stunt but all it's really showing is that VC is still incredibly stupid with their money. All the more reason to seize it from them then properly fund useful software and not subsidize vanity projects for stanford grads.

About the friction, not the capabilities...I haven't switched off my biz calendar/appointment provider I'm paying for even though I've kinda outgrown it.

I wouldn't under estimate switching friction.
