My wife is a life coach. The coaches she knows are all using Zoom for coaching sessions, previously Skype.
She will be using it for webinars that last longer than the free membership allows. So we are now paying Zoom $14.99/month (for the foreseeable future). Life coaches are a drop in the bucket for the TAM. But it seems to me, that this is what the cool kids are using (because it works), and I expect the network effect to continue.
