In the reality television program Shark Tank, aspiring entrepreneurs are pitching their proposals to a panel of experienced investors or “sharks”.

And If pitched successfully, the shark will serve as a business partner and provide funding for the company.

To learn more about the sharks on Shark Tanks and Shark Tank guest sharks, keep reading this article!

What is Shark Tank?

Shark Tank is a show about inventive business ventures in which aspiring entrepreneurs present their ideas to a panel of six rich investors known as "sharks”, namely;

Mark Cuban, Robert Herjavec, Barbara Corcoran, Kevin O'Leary, Lori Greiner, and Daymond John. 

Aside from them, sharks are also inviting shark tank guest sharks to be part of the program. 

The show is modeled on the Australian format "Dragons' Den," which featured aspiring entrepreneurs pitching business ideas to a panel of investors in exchange for shares or a portion of earnings. 

Sony Pictures Television adapted the U.S. version after acquiring the international rights to the format from creator Andrew Proctor in 2008; it was created in collaboration with Australian pay television provider Foxtel when it first aired.

The premiere

In 2009, American Broadcasting Company (ABC) broadcasted the premiere episode of Shark Tank.

This program was an instant smash, and millions of viewers tuned in to see budding entrepreneurs pitch their products to the sharks and shark tank guest sharks. 

In the show, aspirants hope that at least one of the sharks will invest in their business, product, or invention.

Because of it, since its debut in 2009, the show has been a hit. In 2017 it received the Primetime Emmy Award for Outstanding Structured Reality Program.

Since its premiere on August 9, 2009, Shark Tank has aired every Friday at 8:00 p.m. ET on ABC. In March 2010, TVtropolis began airing the show in Canada and other countries.

The series has been renewed for multiple seasons, and as of September 23, 2022, it is now airing its fourteenth season.

The goal of Shark Tank is to help entrepreneurs, who have a high-potential business idea, realize their dreams by acquiring funding from one or more investors. 

The flow and how it goes

Each week, aspiring entrepreneurs pitch ideas to five wealthy investors, or the shark tank casts Mark Cuban, Daymond John, Kevin O'Leary, Lori Greiner, and Robert Herjavec. 

If the shark tank judges like an entrepreneur's business plan, and are impressed with their presentation style, they're eager to invest in that company.

According to the show's official site, "Over the past seasons, nine companies have received investments from all five Sharks and gone on to raise over $68 million in combined venture capital funding." 

The show is a hit with viewers and has inspired many people to pursue their dreams. In fact, there are several websites dedicated to helping aspiring entrepreneurs learn how to pitch their business ideas.

Daymond John

Daymond John, or "The Black Steve Jobs", is an entrepreneur, mentor, and investor famous for his role as the founder of the clothing company For Us By Us (FUBU) and one of the sharks of ABC's "Shark Tank".

Daymond John


Daymond was born in New York, United States, on February 23, 1969, to Margot and Garfield John. He was raised as an only child in Queens, New York. Their family was not wealthy, so he was taught the value of hard work at a very young age. 

Unfortunately, his parents got divorced when he was 10 years old, leaving him alone with his mother causing him to take on the responsibility of being a breadwinner and begin working. 

After a few years, he discovered that he is suffering from Dyslexia and he decided to stop his studies and wanted to start his own business.  

But to fulfill this, he needs financing. Therefore, he started working as a waiter to save enough money for his business endeavor.

Daymond founded his first company using a talent he learned from his mother. He purchased cheap cloth and stitched 80 wool caps, selling each for $10. This first venture in business earned him $800, which boosted his confidence.


In 1992, he launched his company "For Us By Us" with his mother's investment of $100,000. Additionally, he expanded his company to include the production and sale of screen-printed T-shirts. 

The breakthrough for FUBU occurred in 1993 when he convinced his childhood friend and rapper LL Cool J to wear a 'FUBU' T-shirt to a public event. 

Later, when shooting an advertisement for 'GAP,' Cool J wore a 'FUBU' cap and included the line "for us, by us" in one of his rap songs.

In 1994, he received $300,000 in orders. To produce the products, he needed to increase their workload, which needed additional funds. He requested loans from numerous banks, but 27 of them denied his requests. 

His mother raised funds and placed an advertisement in The New York Times.  The move was successful, as 'Samsung Textiles' joined the team and assisted 'FUBU' in fulfilling the orders.

Sharks in a Tank

The biggest lesson you can take away is that Shark Tank, and I’m sure this applies to all side hustles or business in general, it takes a lot of time. Time is the most valuable thing we have as humans. 

The problem with most side hustles is that they can take up so much time that you don’t have to give up anything because you won’t have quality time in your daily schedule to do other things.

No matter what business you’re involved in getting started will take some time but if you are passionate about it and take action daily then sooner or later success will come as long as you put in the hard work needed to achieve it!

What we can learn from the shark tank casts, may it be the main sharks or the guest sharks, nothing comes in an instant.

Most of them started from nothing, and most of them started as nobody. But after a long time of hustling with their dreams and aspirations, they got to the peak of their success.

Just always remember that to reach our goals, we have to set our priorities straight, be persistent, and work hard. Success comes after our patience, discipline, and courage! 

Aside from it, I hope that you learned some tips, techniques, and even business ideas that were discussed in this article that might be aligned with the things that you like and you want to do.
