This is impossible to answer, because investors thinking totally other way. Investor want to see MARKET fit. They are reasonable people, but best you can do, give them formula with good foundations, like: "if on January 10, you invest x1 amount of cash, in x2 days will receive product, which x3 number of people will buy for x4 dollars, before end of year". For example, for Arduino-like products, number of potential customers is just about few millions persons, and it have relatively low barriers for new producers. Because of these characteristics of Arduino-like market, there near impossible to make profitable full scale semiconductor business, as you will need to fight your niche vs many other producers. So ALL Arduino businesses, really use "two-legs" business model, or "many legs", where Arduino product is just one income source and exists one or more other powerful income sources. Other example, Amazon Ring. From first view, they are just digital camera business for very specific niche, not very sophisticated technically. But to defend their market from other producers, they registered somewhere about 80 patents, which tightly cover their niche and some nearest neighbors. Really exists many variants of limitations, which could defend your market from other producers, but this is too broad talk, to speak from what you already tell. So, what I still trying to say - you going wrong way, you need to talk with investors on business language, not technical language.
