I just called your voice demo, and immediately started sending the number to my friends. What an incredibly impressive and convincing demo. I'm going to update my standard mentoring wisdom: the only thing more compelling than a great product video is a phone number that you can call to have your first voice conversation with an AI.
If HN allowed memes - and thank goodness that it does not - there would be a room full of sombre gentlemen slow-clapping for you right here.
I hope that number survives the ineveitable deluge. How many callers can your system handle simultaneously?
