Michael Gary Rubin was born on July 21, 1972, in Philadelphia, Pennsylvania, to Paulette and Ken Rubin. His mother was a psychiatrist and his father was a veterinarian. He was raised in a Jewish family. He grew up in Lafayette Hill, Pennsylvania, where he started a ski-tuning shop in his parents' basement when he was 12 and two years later, using $2,500 in bar mitzvah gifts as seed capital and a lease signed by his father, he opened a formal ski shop in Conshohocken, Pennsylvania, named Mike's Ski and Sport.
Rubin was educated at Plymouth-Whitemarsh High School. By the age of 16, he was some $120,000 in debt and was able to settle with his creditors using a $37,000 loan from his father under the condition he attend college. Rubin agreed, continuing to operate the business, which grew to five ski shops before he entered college. He attended Villanova University for a semester before dropping out after realizing a large gain on an opportunistic transaction. This involved buying $200,000 in overstock equipment at a deep discount with $17,000 borrowed from a friend and re-selling it for $75,000.
Using the proceeds from his serendipitous overstock transaction and after selling his ski shops, he founded the athletic equipment closeout company KPR sportsâÂÂnamed after his parents' initialsâÂÂwhich bought and sold over-stock name brand merchandise. In 1993, the year Rubin turned 21, KPR reached $1 million in annual sales. By 1995, KPR reached $50 million in sales. In 1995, Rubin purchased 40% of the women's athletic shoe manufacturer Rykä.
