Early life and education
Michael Gary Rubin is a 52-year-old American businessman who was born on July 21, 1972, in Lafayette Hill, Pennsylvania. He was raised in a Jewish family, where his father was a psychiatrist and his mother a veterinarian.
Rubin’s entrepreneurial drive began when he was a young boy. At 12, he started a ski tuning shop in his parents’ basement. By 14, he had started Mike’s Ski and Sport using $2500 from his bar mitzvah gifts.
He attended Villanova University but dropped out after one semester to focus on his entrepreneurial interests. His practical mindset has driven him to become the successful businessman he is today.
Entrepreneurial Journey: From Ski Shops to GSI Commerce
Rubin sold his ski shop and launched KPR Sports, a company that sold discounted athletic equipment. This investment laid the foundation for his dominance in the sports retail industry. By age 21, Rubin’s company had reached $1 million in annual sales. Within two years, KPR had attained $50 million in annual sales.
In 1998, Rubin founded Global Sports Incorporated, which he later rebranded as GSI Commerce, an e-commerce platform. The company grew relatively fast, serving global brands and major leagues. His most significant financial breakthrough came in 2011, when he sold GSI to eBay for 2.4 billion. However, eBay only retained the order fulfillment segment, allowing Mike Rubin to buy back the consumer segments at a bargain price.
The birth of Fanatics: A sports merchandise powerhouse
After repurchasing GSI’s commerce consumer businesses, Rubin founded Fanatics, a dedicated sports merchandise company. The company grew rapidly, quickly becoming the world’s largest retailer of licensed sports apparel and memorabilia. The company adopted a direct-to-consumer model that allowed it to manufacture, distribute, and sell products seamlessly.
With Fanatics, Rubin:
- Secured exclusive deals with the National Football League, National Basketball Association, Major League Baseball, and NCAA,
- Managed to control the entire supply chain—from manufacturing to retail,
- Expanded to the sports betting industry, making Fanatics a one-stop-shop for fans.
By 2025, Fanatics’s estimated valuation flies in the tens of billions.
