I am trying to get my head around why set up one of these businesses when Uber, Doordash exist, and it is a network effects game, where you need the most drivers to be trusted, the drivers need to see you as worthwhile as do the customers and the restaurants. So it is not just chicken/egg but maybe hen/rooster/egg problem.
Unless your plan is selling to the well funded startups who reckon they can muscle in?
What might make a bit more sense is if this is used by the restaurant who employ their own riders, but that is a dying breed I reckon.
