The problem isn't technology but logistics. How are you going to find a large pool of drivers ready to take food instantly from point A to B in the city at little/no cost?
I thought this was such a fabulous idea, I bought a domain name for it: https://inmytown.org/ As usual, I just haven't done all the other hard work. But, in the old days last year, I thought it would be cool for local shops to have an online presence so that online shoppers could see where to buy stuff and place orders and then pick it up. So, have an e-commerce platform for shops, restaurants, delivery would be great. Try and keep money local instead of shaving 10-20% off of all transactions and sending them to big tech. Does anyone want to help me build this? Totally committed to non-profit and great apps for local companies.
