The owner of 150 companies, Mark Cuban is best known for his straightforward entrepreneurial advice on Shark Tank and his incredible turn-around of the Dallas Mavericks, the NBA basketball team which he has owned since 2000. The self-made billionaire offers frank input on building businesses and growing wealth based on decades of experience.

Some of Cuban’s well-known companies include Magnolia Pictures, Landmark Theaters, AXS TV, and the Florida-based Alyssa’s Cookies, one of his most profitable Shark Tank investments. Since he joined Shark Tank in its second season, the ABC reality show’s ratings have steadily climbed and the program has snatched three Primetime Emmys for “Outstanding Structured Reality Program.”
