I first met Zachary Karabell when he was enrolled in my Columbia Executive Education program "Leading Strategic Growth and Change" and he made a big impression on me all those years ago. I'm delighted to catch up with him to talk about his rich collection of activities - he has a brand new book out about Brown Brothers Harriman and the way capitalism used to work. He is an author and columnist, the founder of the Progress Network at New America, and president of River Twice Research and River Twice Capital. He's written many other books and is a regular columnist and commentator. An all around fascinating person I'm looking forward to chatting with.
