Congratulations on securing capital for your project. Been through the same journey of startup to selling a product that was not fully developed. While I have not actively pursued funding in my ventures, what I learnt is investors will ask for more than financial projects. They will ask for patents, contracts for delivery of the finished product, your plan to beat the competition (if any) and you plan for scaling distribution.
Wish you all the best in your venture. Happy to hear someone pursuing production as a venture rather than everyone pursuing mobile apps and technology.
