Congrats on getting this out! I recently started on my own startup and like you I always feel behind.
That aside, I've heard many people in the NY area ask for a service similar to this, but for managing whole buildings. Do you have an idea of what your initial target market might be?
Also, the video is very well done, but you make the assumption that someone would want to watch that to learn more about your site. I'd add some text for those that prefer reading.
Good luck!
