Thanks for those insights. I agree with your contention that a business model that worked in a different setting or geography may not be easily replicable in another setting. Several businesses built around the hyperlocal model have failed badly, but there are multiple lessons out there from these failures.
For e.g. expanding into multiple geographies with a bullish outlook--this hasn't worked for grocery delivery startups in the past. Now instead startups like Milkbasket, DailyNinja, Dunzo, etc. are expanding within colonies/residential blocks, and towns, rather seeing expansion as a multi-geographical function. There are more such lessons, but even the new hyperlocal models will not be unit positive from Day 1. Discounting and cross-subsiding will bear huge costs for Swiggy, and they might fail in 1 or 2 categories, but at the end of the day, if Swiggy can amass even 10k new user sign-ups from their new verticals, they could be re-targeted with food or other categories for example.
