Jack Ryan has been described as the renegade of the $3 trillion residential real estate industry. He is the co-founder of REX—the digital alternative to the Realtor™. Jack began interacting with the US Department of Justice and State Attorneys General Offices in 2018. He has successfully pointed out that the price-fix engineered by the realty industry is a cartel larger than OPEC in terms of the amount of money transferred from middle-class Americans to industry. His commentary had been published in the Wall Street Journal and by prominent antitrust organizations. Jack has founded other successful companies and has served on the boards of private and public companies. Prior to these business activities, Jack taught at Hales Franciscan High School on Chicago’s south side. Before joining Hales Franciscan High School, he was a partner at Goldman Sachs & Co where he worked from 1985 to 2001. He participated in both investment banking and securities trading activities. He is a graduate of Dartmouth College summa cum laude, and Harvard Business School and Harvard Law School with honors. He currently resides in Austin, Texas.
