Let me be the devil's advocate for your idea and excuse me for this. Take it more like a honest advise rather than a criticism. VCs or investors looking to fund a Startup usually get reluctant to ideas which are far fetched into forward and backward integration. If you pick up one problem and focus more on that component and slowly integrate either forward or backward after scaling the prime idea , and focus on the integration and scale of second component to a level when the third component can be added seamlessly . It's not that the components of your closed loop system are not aligned, they are workable models but nobody would give their precious glass mugs to a juggler on their first day. Either you bootstrap things, simultaneously start all the three and get the machine running at a momentum, create a profitable business from that. Everyone would love to jump on the idea at this point. Or else , pickup the strong component and create the business on it and scale it to a level and pitch your idea of one of your integration to the investor and the grand scheme of closed loop system as the third step , only if the second step is successful. It is important to know that, IDEA is one of the simplest thing someone can come up with, execution is the point where all the chaos happens. Good luck anyways
