Flipkart has managed to scale its revenue but without making a profit. Even this would have appeared as a good opportunity if Flipkart was kind of de-facto e-commerce business in India. Turns out that it is not. Snapdeal, Junglee (Amazon India) are pretty close. Myntra was the leader in apparel and fashion products sale online which was then acquired by Flipkart. (Myntra was not profitable either).
I find it hard to understand why anyone believes that Flipkart would ever make profit in next 5 years or so. I find it hard to believe.
Unlike USA, India has not yet figured out how to build proper usable roads, the cities are not planned and India does not have a proper addressing system. Government regulations have further made life difficult for courier companies. All this has resulted into cities and towns where traveling over few kms is very expensive and time consuming as a result small shops catering to need of local communities have sprung up like mushrooms. Current India is probably resembles more to the A&P days of USA.
My assertion is validated by the fact that Travel Booking and Movie ticket booking websites in India are growing fast and also very profitable.
