In this week's episode of Walk The Talk, Sachin Bansal & Binny Bansal, the founders of Flipkart that has revolutionised India's online retail business scenario, revel on the journey from being a couple of engineering graduates from IIT-Delhi to challenging the country's retail sector and helping anyone purchase almost anything at the click of a button. Mistakes were made and several of them, they say, but important was what they learnt and how they perservered on improving their application. They talk about how technology will no longer be necessary but simply available and also what other sectors they wish to challenge.
