Quick Facts

From Local Ambition to Global Success

Mark Cuban’s story begins in Pittsburgh, Pennsylvania, born July 31, 1958, into a working-class family where ambition and hustle were early lessons. He parlayed his early ventures — selling garbage bags, stamps and coins as a youth — into bigger bets: while studying at Indiana University, he gave disco lessons and ran businesses to stay afloat. 

After graduating, Cuban moved to Dallas where he co-founded MicroSolutions in the early 1980s and later, with Todd Wagner, the streaming pioneer Broadcast.com in the mid-1990s. That company’s sale to Yahoo! in 1999 for roughly US$5.7 billion in stock became a defining moment.

Defining moments in Mark Cuban’s journey include:

• Launching MicroSolutions and selling it for millions early in his career.

• Co-founding Broadcast.com and executing a landmark exit via Yahoo!.

• Buying the Dallas Mavericks in the year 2000 and steering the franchise to new heights.

• Becoming a judge-investor on the hit show Shark Tank, translating his entrepreneurial story into media presence.

• Co-founding Cost Plus Drugs in 2022 to disrupt prescription-drug pricing and diversify his portfolio.
