Good luck with your project! Others have already told you to talk to your future customers, so I'll skip that part. What I do want to impress is to think about not just who your users are, but who will be the stakeholder and purchasing decision-maker. Once you have a running product, it will have to both work well technically but also be a sensible (and safe) purchase for whoever makes that decision. As they will certainly research the company, I would make (planning/engineering for) operational stability and scalability a central part of your messaging :) And, most of all... have fun building both a product and a business.
