Tom Hardin

Tom Hardin

Tom Hardin previously spent much of his career as an investment analyst in the financial services industry. In 2008, as part of a cooperation agreement with the U.S. Department of Justice, Tom assisted the U.S. government in understanding how insider trading occurred in the investment management industry.

Known as “Tipper X,” Tom became one of the most prolific informants in securities fraud history, helping to build over 20 of the 80+ individual criminal cases in “Operation Perfect Hedge,” a Wall Street house cleaning campaign that morphed into the largest insider trading investigation of a generation. As the youngest professional implicated in the sting, Tom was tasked with wearing a covert body wire on over 40 occasions to help the FBI bring down some of its biggest targets in the industry.

In a reunion of sorts, Tom was invited by the FBI-NYC’s office to speak to their rookie agents in 2016 and is now a global keynote speaker, corporate trainer and board advisor on behavioral ethics, the fraudster mindset and organizational conduct and culture risk. Through rigorous self-examination, Tom took responsibility for his actions as a young professional, used the experience to transform his life and is now on an on-going journey into behavioral science and why professionals sometimes make the wrong decision.

Tom holds a B.S. in Economics from the Wharton School at the University of Pennsylvania. His riveting life story is the subject of a forthcoming book, The Inside Story of Tipper X.
