This is actually food delivery, not general stuff. Perfect timing and perfect market imo.
Zepto was getting into it too with zepto cafe. If you can get food in 10mins, why would you wait 30-60 mins?
It's so obvious to see the benefit. Customers can quickly order something else in case order fails. The frustration that happens when you don't get food even after waiting long is immense, especially late night deliveries when mostly everything is shut except few places.
This already happens on a basic level, people have 2-5 favourite nearby options they go to near their place without thinking much to get food. Now that list can expand.
I changed my mind about quick commerce because it is already profitable. Can't ignore numbers and pmf. Food is simply an extension of a good enough market that's been opened up by QC.
