A big ? for DoorDash is how big can they really be as a company. Too many people are making a big deal about their profitability as a whole. But if you look at customers at a cohort level once customers get to years 2,3,4 they are actually profitable. The big question is what is the average lifespan of a customer for them, do they make it to years 2,3,4, how far in do they make it and at scale how much profit can they expect to make from each customer that does last that long. Then when that is all said and one what size company are we lookin at? $1B in annual revenue?, $10B?, $100B? That will determine the viability of DoorDash and its size as a public company.
I think the better question is, how loyal are the customers, personally - I am going to go for the cheaper of the platforms. Especially knowing that the drivers are basically all the same.
The cohorts are similarly profitable when they get to 2020, the year when there was a massive pandemic that forced everyone to order in all of the time.
