What are some of the key decisions Cuban made that led to his success?

Cuban went from offering dance classes at $25/hr to afford tuition at Indiana University to becoming a billionaire by a lot of hardwork and a bit of luck.  Here are some choices he made to get there.

1. Cuban decided to start his own company, MicroSolutions, in 1982.

Who could have guessed that walking away from a $1,500 commission opportunity would lead to owning a $6 million brand 9 years later? 

After Mark lost his salesman job with YBS, he dared to start his own business called MicroSolutions with Martin Woodall’s help. 

His new company competed aggressively with his former brand. He offered (Personal Computer) PC consultancy, learned to write his own programs, and studied Lotus. 

MicroSolutions resold products from TeleVideo and Novell and also provided local-area network services. He grew MicroSolutions to $30 in annual revenue.

2. Cuban decided to sell his company, MicroSolutions, in 1990 for $6 million.

In 1990, Cuban chose to sell MicroSolutions to CompuServe for $6 million. This choice made him a millionaire and gave him the foundation and funds to start Audionet, an online streaming company with Todd Wagner and Chris Jaeb. 

3. Cuban decided to buy the Dallas Mavericks in 2000 for $285 million.

Cuban also decided to buy the Dallas Mavericks one of the worst performing basketball teams of the 90s for $280 million in 2000. They went on to become championship material under his leadership. Currently valued at an estimated $3.3 billion, he literally took them from worst to first.

4. Cuban decided to invest in in 1999.

Remember Audionet? Cuban and his co founders renamed it He bought up most of Jaeb’s shares, a decision that would make him even more money in the future. 

5. Cuban decided to sell his shares in to Yahoo in 1999 for $5.7 billion.

By 1999, the company had grown to 330 employees with $13.5 million in revenue. Yahoo later bought the company that year for $5.7 billion in Yahoo stock. 

Yahoo’s shares were selling at $163 at that time. Cuban locked up his shares. When the lockup ended, he sold all his shares because he foresaw the dotcom bubble burst. Cuban made a fortune worth $2.5 billion by this move. 

About 18 months later, Yahoo’s stock price began to fall till it hit $30 per share. By December 2001, it plummeted to a record low of $8.11, about 95% short of the price point where Cuban sold.

If Cuban hadn’t sold his shares, they would’ve been worth $125 million. Since then, Cuban has grown his wealth by investing in other businesses.
