My guest this week is Brad Katsuyama, the founder of the IEX exchange and protagonist of Michael Lewis’s famous book Flash Boys, which chronicled the role of high frequency trading in markets. This conversation was yet another reminder of how complicated markets can be, and that very few participants know all aspects of the process well. Brad and I get deep into the history behind his company, and the ways in which markets and exchanges have evolved, better or worse. One of my favorite parts of this conversation was our exploration of entrepreneurship. Brad’s whole story is one that entrepreneurs will appreciate, and is full of lessons for those aspiring to start their own business.
