In this episode I interview Ari Akerstein, an expert on e-commerce and most recently one of the product leaders at Walmart.com. We all buy things online, but it is not clear from the outside how data is used to turn a click on a website into a cardboard box on your doorstep. Ari walks us through the use of data at one of the world’s largest e-commerce companies and how it’s used to build and optimize e-commerce products.
