A small piece of feedback. On this page: https://www.appointmentreminder.org/a/calendar - I am wary of testing it because I'm not sure who'll see my phone number if I do. In other words, it's not clear if this demo is just for me or if this is a "demo sandbox" for anyone to use.
BTW, love the outrageous enterprise pricing that makes the small business plan look better, as well as the blatantly fake "HOT" tag - you shipped today! it gets hot fast in Japan! ;)
Not so sure about this "All questions are answered by our lead engineer. (Your business is too important to trust to a call center..)" - smells a little bit fake. I like Garrett's style better: http://sifterapp.com/support (scroll down to the green box).
Just my quick first impressions. Congrats on a new beginning!
