Hi,
The introduction video is quite impressive, you have voice over and not a home made video so +1 for that, I don't think I would afford the budget to do such a thing.
If I was to give you a purely personal opinion as to why it would not be of interest to me it would simply be because a blind opener and closer, to me, is not something that I feel should be a standalone product, it seems as though such a device should be a "node" in a home automation network, it seems a bit over kill to use your phone to just open your blind, if you wanted to use home automation to control your lights and sockets, etc, you would need a different number of apps for each setup.
I hope it picks up as it is an interesting idea, I just think the context in which it is being presented is too stand alone, but, purely personal opinion.
