If you do manage to find a niche, then you're invited to a whole new circle of hell in fraud mitigation and chargebacked invoices. You need a really good idea to break into the current scene.
Initial ideas are easy, execution is harder, and maintaining it across time and devices and changing tech is very hard. Delivering static things like books or phone cases or laptop chargers is one thing. Delivering food is a completely different ball game.
I agree with your overall sentiment though, we'd all be better off if our food originated nearer to us and we had the proper systems to make local food more profitable for smaller food producers. But Amazon, WalMart, Costco, Hello Fresh, Full Circle, Blue Apron and dozens of other very deep pockets make it very difficult to keep up. You have to be better at something besides price or convenience, because they're run circles around you with those two. For example, you have certain advantages when you're "small" that an Amazon just simply can't compete with. Things like quality, small quantities, hyper-local, hyper-fresh, customer service, high-touch items, etc. Amazon has disadvantages because of their scale, so lean into those areas that don't scale to get some traction.
This still stands. How many potential customers have you since talked with to de-risk the very "market existence" aspect first?
Why? It doesn't have to be the idea itself. You can ask questions to check whether it is a problem first as opposed to talking about your solution. What if they're not aware it's a problem, or don't care about it? It's harder to sell a solution to a problem to someone who is not aware of the problem or does not care about the problem than it is to someone who's well aware, who cares about it, and who's tried to solve it but failed.
>and because my app would require some kind of technical infrastructure i don't wanna start talking with local restaurants.
Why?
>i feel like i can convince the big boys and the locals would follow them.
Feel? Wouldn't having actual conversations and learning things that are invisible to you right now beat that and shed light on many things?
