Paul got his undergraduate degree in India and came to the U.S. where he earned an engineering master's degree at Temple University in 1994. He went on to work for Synthes, a Swiss medical device maker owned by billionaire Hansjoerg Wyss, before quitting in 2003 to found Globus Medical. Since 2014, shares of Globus Medical, Paul’s publicly traded device manufacturer, have more than doubled. Just since the Excelsius Surgical robot received FDA clearance in August 2017, the stock has climbed 65%. Paul owns nearly a quarter of the firm. That stake and recent stock sales add up to a $1.3 billion fortune. Paul, who stepped down as CEO and moved to the executive chairman role last year while recovering from what the company referred to in a press release as a “health condition,” still maintains tight control over the business—owning 76% of the company’s voting shares, according to the latest proxy.
