From reading the blog post linked from the article, DoorDash doesn’t actually make money. Someone who understands finance better, what is the longer term play here? Is it to optimize to grow and then raise prices in the future?
Same as Uber &co. Kill competitors by selling at loss and achieve monopoly. Which will never work because there is almost no barrier to entry in these businesses.
Very high marketing, legal, etc costs and highly optimized/intelligent routing, scheduling system within an app.
