"While we don't have any physical prototypes at the moment... working on building traction via preorders... start building hardware once fundraising is complete

"While we don't have any physical prototypes at the moment... working on building traction via preorders... start building hardware once fundraising is complete" Sorry mate, I stopped reading at this point. It sounds like you might be trying to tackle too much at once. Unless you have very deep pockets (which I'm guessing isn't the case since you haven't secured funding yet) you might be better served finding a route that gets you there via smaller steps with discrete wins along the way. If there are companies out there as you've described who are good at one piece, consider starting with a product that works well with the portion of the puzzle they already solved - perhaps with an eye to eventual acquisition (them of you, or possibly you of them once you've built up a reputation for execution and growth in this space that will attract sufficient capital). It's along the same lines of reason aircraft companies don't generally build a new engine and airframe at the same time. Even Apple started off with a simple music player before they grew a whole iOS ecosystem. It sounds like you have a clear vision and your past experience will serve you well. I'd really love to see innovation in this space and wish you luck. One other gut feeling from reading this that I have to share, which may be painful for you to hear... the timing of your post and its similarities to a Kickstarter come across like this is really more of a pitch to drum up attention and VC funding.
