For more than ten years, viewers have enjoyed the American television programme Shark Tank. A group of affluent investors known as "sharks" listen to pitches from prospective company owners and

determine whether or not to invest in their ventures. The Dallas Mavericks owner and self-made millionaire entrepreneur Mark Cuban is one of the most well-known sharks on the programme.

One of the richest businessmen in the world is Mark Cuban. He acquired his wealth by selling his first business, MicroSolutions, to CompuServe in 1990 for $6 million.

He later founded, which he later sold to Yahoo! in 1999 for $5.7 billion in equity. Together with Magnolia Pictures, Landmark Theatres, and the AXS TV network, he also owns them.

Together with his commercial endeavours, Cuban is renowned for his charity efforts and outspoken demeanour.

In 2011, Cuban joined the cast of Shark Tank, where he quickly rose to the position as one of the program's most adored sharks.

He is recognised for his quick wit, strong negotiation techniques, and willingness to invest in fresh and inventive ideas.

He has invested in a number of businesses featured on the programme, such as Simple Sugars, a cosmetics firm that only

utilises natural products, and Ten Thirty One Productions, which organises Halloween-themed events. When Cuban made an investment in the

Groovebook startup, it became one of his most enduring Shark Tank moments. Customers may print out book-sized images from their smartphones using the company's subscription service.

The creator, Brian Whiteman, had originally requested for $150,000 in exchange for 5% stock in the firm.

Cuban made Whiteman an offer of $150,000 for 80% of the business after being impressed with the product. Once Whiteman accepted the offer, Shutterfly paid $14.5 million to purchase the business.

Cuban is also known for his kindness on the programme. A young entrepreneur called Lani Lazzari made a presentation for her all-natural skincare business, Simple Sugars, in one episode.
