Who Are The Sharks?

#1. Mark Cuban

Net Worth: $3.4 billion as of April 2017, according to Forbes

The Divine Prayer

Book Published: How to Win at the Sport of Business

Mark Cuban, from Pittsburgh, Pennsylvania, is one of the most memorable sharks. The outspoken owner of the NBA team “Dallas Mavericks” has an impressive net worth of 3.4 billion dollars. Mark is an entrepreneur at heart, starting his first business venture at the young age of 12, when he sold trash bags door-to-door.

Cuban’s first company, MicroSolutions, started off as a small PC software retailer in Dallas Texas, being sold in 1990 for an impressive 6 million dollars. Cuban quickly moved on to his next investment:

With big dreams and even bigger ambition to match, Mark and his co-investors were on the frontline of internet broadcasting, becoming in 1999 the first company to help air online the world-famous Victoria Secret Fashion Show. The company was sold the same year to Yahoo for 5.7 billion dollars in Yahoo stocks. After these first initial investments, Mark broadened his portfolio, sharing some of his wisdom and money with companies, such as,, Naked Pizza, and

In 2000, he purchased the basketball team “Dallas Mavericks”, which lead to a media storm and several doubts regarding Mark’s ability to be a savvy NBA team owner. Once again driven by his ambition, Cuban took the stadium and the game-viewing experience into a whole other level, quickly silencing all its critics. Since then, he has invested in several TV and movie companies, further helping him establish himself as a force to be reckoned.

Voted in 2006 as GQ’s “Man of the Year”, Mark’s good looks have also given him the chance to appear on several other TV shows and movies, such as the infamous shark-themed blockbuster “Sharknado”. More than just a pretty face, Cuban has also written a successful business book “ How To Win At The Sport of Business”.

Regarding his “Shark Tank” career, Cuban was first introduced as a full-time cast member during season 3, although he had made a previous appearance on the show as a guest shark back in season 2. He has invested an impressive amount of almost 20 million dollars as a shark, with one of his biggest investments being on the company “Ten Thirty One Productions” for a staggering 2 million dollars.

Although he may come across as a big spender, Mark has only invested in 19% of the 443 pitches heard over the course of 111 episodes of the show. He is also known for teaming up with other sharks, and over 50% of the deals made are in collaboration with another cast member and fellow shark.

Mark Cuban is not only a smart and hard-working businessman, he is also a TV personality and celebrity who isn’t afraid to share his opinion. We are as curious as you are to see if on the next seasons, Cuban will invest in more diverse ventures or if he will stick to his area of expertise: media and technology.

#2. Robert Herjavec

One of the most lovable sharks, Robert Herjavec is a Croatian native whose parents immigrated to Canada when Robert was still a child. His true success story has been used as inspiration by hundreds of young entrepreneurs, businessmen, and businesswomen alike.

Herjavec started his career as a self-made entrepreneur when he created his own Internet security software integrator, BRAK Systems. Although in the company’s early days he was waiting tables in order to support himself and his family, as the company’s innovative approach and technology started to get more attention, Robert managed to strike a deal with AT&T Canada, selling the company for the impressive amount of 30.2 million dollars.

That wasn’t Herjavec’s only big win, as he later sold another one of his Internet companies to Nokia for 225 million dollars. Always with a goal in mind, Herjavec moved on to his next business venture, one that further cemented his role as a brilliant entrepreneur and where he now serves as CEO: the Herjavec Group, a company focusing on IT security and infrastructure integration. One of Canada’s fastest growing technology companies, the Herjavec Group has racked up around 500 million dollars in sales… and that’s just since 2003!

Robert is one of the original cast members, being an official shark since the show’s 1st season. He has definitely shared some of his wealth and knowledge, having invested over 16 million dollars on the show so far. With 57 deals out of the 511 sales pitches heard over the course of 126 episodes, Herjavec invests in only about 11% of the companies who decide to present their pitch on “Shark Tank”. But don’t get the wrong idea!

Although Robert is not the quickest to take the bait, when he hears a good idea he usually makes quite a large investments. His biggest one to date is the staggering 5 million dollar deal with Zero Pollution Motors for a 50% stake in the company. Another note-worthy investment from the seasoned technology expert is the 3 million dollar deal with the company SynDaver Labs, for 25% stake in the business. Robert is also known for partnering up with other sharks, with over 50% of the deals so far being made as a joint venture with other cast members.

With a truly inspirational success story, Robert managed to immigrate to Canada with less than 20 dollars in his pocket, to being one of the savviest investors in the technology field. Did you know Herjavec actually started his career in the film industry? Moreover, he is an excellent writer and more about his personal life and early days can be read in his books “Driven: How to Succeed in Business and Life”, released in 2010, and “The Will to Win: Leading, Competing, Succeeding”, released in 2013.

Perhaps one of the most outrageous sharks, Kevin O’Leary is the amazing businessman who is not afraid to pet himself in the back. Originally from Canada, O’Leary first started his business career as a TV producer. Quickly getting the hang of the business world, O’Leary worked and invested his way to the top, with a net-worth currently set at more than 400 million dollars.

But how did he go from TV into the finance world? After selling his share of the company Special Event Company to his partners and college friends for 25 thousand dollars, O’Leary then started his own company, Softkey. The company, a publisher and distributor of software for both Windows and Macintosh, went through some hard times.

With O’Leary’s expertise and thrive to succeed in hand, Softkey managed to bounce back from the recession and later bought The Learning Company (TLC) for an impressive 606 million dollars. Years later, the company was sold to Mattel, and O’Leary later departed from the company. But not without making some waves first! A lawsuit was filed and O’Leary ended up receiving a 122-million-dollar settlement.
