Complexities of Marketplace Businesses

I’ve spent a little under three years working at marketplace businesses in my career (Blinkit and UbeEats). Without going into too much details for obvious reasons, I’ve scribbled a few dimensions that add immense complexity to them (with 3P models being significantly more complex). Each of these areas is deep enough to require a PhD of its own. Each area is run as a dedicated charter within startups and big tech.
