Let me quick this off with some obvious ones.
1) retail health = only 35M lives insured as of FY18
more 👇
3) life = estimates peg penetration at ~25% lives; however claim significant under insurance at ~10% of the desired sum cover
5) views on other categories like crop, marine, fire, home etc?
6) digital attachment insurance = this has got muted success (with selective products gaining traction like Ola trip insurance, OTA's (flight) trip insurance, OTA's flight cancellation insurance, Amazon's mobile screen insurance etc)
Please add to this list. Also correct where my knowledge is not correct. Also add insights into for eg - why under insurance in life.
