10 Biggest Deals on Shark Tank

The biggest deals on Shark Tank are the most surprising and exciting ones in the show’s history. The show that is known for its innovation and shock value has seen some of the most outrageous business deals being made on air! The viewers have been awed time and again at how the simplest or the most ridiculous business ideas could actually grab the interest of investors and even prove to be great successes.

The reality TV show has some of the biggest entrepreneurs on its panel of ‘shark investors’ who listen to pitches by contestants who are aspiring small time entrepreneurs, who ultimately get a deal – that is investment for stake in their businesses or get rejected. Either way it’s a win-win because a platform as big as the show, with its viewer base is a great opportunity for exposure for these business owners and their products. Sometimes, even when they fail to cut a deal, their businesses experience increase in customers overnight. Some of the biggest deals over time have also featured among the 11 Most Successful Shark Tank Businesses.

However, no business is without risk and even the biggest deals on shark tank sometimes fail to make it a success after they cut a deal on the show. Even though veterans like Mark Cuban, Kevin O’Leary, Barbara Corcoran, and Robert Herjavec, who have been panel members on the show and invested in some the biggest deals, have backed an idea with their investment, the businesses have not flourished as much as they were supposed to. On the other hand even some of the biggest offers were rejected by the contestants themselves for the fear of losing stake in their business. One such case had been the dating app, Coffee Meets Bagel, which received an offer of $30 million in return for the whole business by Mark Cuban. Had the owners of the app the Kang Sister, not rejected that offer it would have made for the biggest deal in Shark Tank history.

Here we have listed the biggest deals on Shark Tank that were actually made, the ones which received whopping investment amounts for stake in the business, and were handpicked by the ‘shark investors’ as potential success stories. Let’s take a look!

10. Drop Stop,

Deal: $300,000 for 20% stake

Creators Marc Newburger and Jeffrey Simon’s simple business idea of a car seat gap filler was a hit with Shark Lori Greiner, who bought 20% of stake in the business with $300,000. The simple yet highly functional product was a device which attached itself to the car’s seat belt to prevent car keys and other items to fall through the seat gap. The business has been growing ever since and they even did two QVCs after the show.


9. First Defense Nasal Screens,

Deal: $750,000 for 20% stake

Small time entrepreneur rejected Robert Herjavec’s $4 million offer for the whole business and they eventually struck for a deal for 20% stake in the business, only to decline even that after the filming of the show. The First Defense Nasal Screens are adhesives that prevent germs from entering the nose and the business has been doing pretty well even without the investment.


8. BeatBox Beverages,

Deal: $1 million for 33% stake

Apparently wine sold in neon colored boxes is a million dollar idea. At least that is what cost Mark Cuban for a 33% stake in BeatBox Beverages. The business has been booming since the major investment it received and sales have been plummeting both online and in retail stores.


7. Breathometer,

Deal: $1 million for 30% stake

Charles Lim’s portable breath analyzer was an instant hit among five sharks who jointly invested in the business. Breathometer went on to become not only one of the biggest deals on Shark Tank but also one of the most successful. The sales reached a $10 million mark within a year of airing of the show and the company has made its presence across international markets.

6. How Do You Roll?

Deal: $1 million for 20% stake

A personalized sushi restaurant chain, How Do You Roll, made an impressive deal on the show with Kevin O’Leary, which unfortunately fell flat soon after the filming. However, that didn’t stop the one of a kind restaurant chain from grabbing attention and it went on to open several outlets across US including one in Los Angeles.


5. Red Dress Boutique,

Deal: $1.2 million for 20% stake

The vibrant boutique based in Athens, Georgia received a stellar deal jointly from Cuban and Herjavec. However, only Cuban’s part of the deal was followed up and an investment of 600,000 was finally received by the company. The situation turned out well for the business though, as the sales right after the broadcast touched $1 million.


4. Hy-Conn,

Deal: $1.25 million for 100% stake

Yet another example of a whopping deal that fell flat off camera. Founder, Jeff Stroope made a deal with Mark Cuban for the entire business which apparently didn’t turn into a success after the show. The business did well, however. And, Stroope was able to spread operations across US, Canada and Costa Rica, while the net worth shot up to $ 5million.


3. Rugged Events,

Deal: $1.75 million for 25% stake

Rugged Events, the organizer of Ruuged Maniac Obstacle Race, managed to win the vote of confidence from Mark Cuban. The insane muddy race of 5km length had already been operating across 20 cities in the country. Since, the big deal the organizers have improved obstacles and expanded operations, with increased revenue.


2. Ten Thirty One Productions,

Deal: $2 million for 20% stake

Melissa Carbone’s one of a kind horror show productions, caught Mark Cuban’s attention who went all out to make an astounding deal of $2 million for a mere 20% stake in the business. Turned out he was right in his decision as the Productions expanded manifold since the show with revenues reaching $2 million to become one of the greatest success stories in the show’s timeline.



1. Zipz Wine,

Deal: $2.5 million for 10% stake

The innovative wine company Zipz Wine managed to make the biggest deal on Shark Tank history, in the latest season of the show. Kevin O’Leary made the whopping record-breaking deal of $2.5 million for a 10% stake in the company that makes packages for single servings of wine.
