Economist Gary Loveman was teaching at Harvard Business School when he went to consult for the Harrah's casino chain in Las Vegas in the late 1990s. Despite knowing nothing about gambling, his insights on customer loyalty earned him a promotion to the chief executive job at the casino group. He took a company that traded at $14 a share and a decade later sold it to private equity for $90 a share. Gary Loveman talks to the FT's Sujeet Indap about how data science is helping executives draw in customers across industries. Music by Podington Bear.
