Even if you’re not a fan of boxing, you’ve heard of Eddie Hearn. He’s the chairman of Matchroom sport, the sporting events company which last year signed a 100 million pound five-year deal with Dazn as it aims to become the Netflix of sport. Eddie also represents boxing beasts like Anthony Joshua, Canelo Álvarez and formerly Oleksandr Usyk. He took over the business from his father, but started by printing the posters himself and sending out tweets to promote his fights. Now, he’s one of the most powerful men in boxing.
