Mark Cuban, the owner of the Dallas Mavericks is known for being many things. A jerk, an entrepreneur, a forward thinking business minded individual. The entrepreneurship part of him has come out when Mention Mobile announced today that Cuban has invested an undisclosed amount in the company. This is his second round of funding for the mobile gaming company, following his initial investment six months ago. Cuban’s minority equity stake in the company will increase.

“This second round of funding solidifies Mr. Cuban’s interest and excitement in the future of Mention Mobile,” said Ryan Ozonian, founder and president of Mention Mobile. “Since first joining forces with Mr. Cuban, we have been in a heavy development cycle of a few properties that we feel are very distinct. Mr. Cuban’s support will allow us to continue to create innovative and compelling apps that are unlike anything else in the marketplace.”

Mention Mobile specializes in mobile games that integrate friends from social networks such as Facebook. Some of their more popular games are Trivia Friends, Doodley, Zombie Bash: Christmas Attack and Get 2 The Nest!

“Mention Mobile’s combination of innovative Facebook integration skills coupled with unique gaming concepts make them a one of a kind venture that I’m excited to further my relationship with,” said Cuban.

Mark Cuban earned his fortune by selling Broadcast.com to Yahoo! for $5.9 billion in Yahoo! stock in 1999 during the .com bubble.
