Jessica Alba talks about how her sickly childhood inspired her to start the very successful The Honest Company, a nontoxic household goods startup. Also, she shares how she tackled starting and building a company, with little knowledge of traditional business. And we have a segment with Benny and Rafi Fine, known as the Fine Brothers. They're digital and traditional producers, writers and directors who, on their Fine Brothers Entertainment (FBE) YouTube channel, have a whopping over 15 million subscribers. They talk about scaling their business and what it's like to work with a sibling. Both interviews are exclusives from the 2016 Forbes Under 30 Summit.
