Tell them you’ve proven the hypothesis and achieved product market fit by showing the data from this one city and say you’re raising capital to take it to the next step.
lol, this is the worst possible idea when you dont actually want to build a business out of it. take all the fun out of a side project and add a lifetime of stress and regrets.
