I hate to be that guy, but...

* Given the traffic in Dhaka, you'll forgive me for not believing your one hour delivery promise.

* The only way I can see to get around the traffic problem is to either go hyper-local (i.e. maintain warehouses in every neighborhood), or have delivery people walk/take rickshaws. Either way, this isn't going to scale to the entire city without a TON of startup capital. Which I'm not sure you have.

* How does YC feel about the inevitable "system loss" that's comes with doing business in Bangladesh?

I'm also very interested to hear how YC intends to maintain management accountability in a business halfway around the world.
