Who Is The Founder Of Define Bottle?
Virginia Beach resident Carter Kostler is the founder of Define Bottle. The idea for the bottle came to Kostler when he was 15 years old and a sophomore in high school.
When Carter was a high school student, he constantly saw his classmates consume sugary drinks in the cafeteria. He developed the idea of making Define Bottle a tasty alternative to these beverages.
Define Bottle was Carter’s idea when he was 13 years old, and the product went from prototype to concept in just six months. It’s a water bottle with two compartments kept separate by a filter.
One compartment contains fresh fruit and water, while the other only has old drinking water. The water that has been infused with fruit filters through, imparting a natural flavor to the water that is consumed. Carter developed the beverage to provide children with superior drinking options.
The number of pop bottles in our refrigerators is out of control. The average American consumes one or two sodas daily despite being aware of how unhealthy they are. You should do that instead of grabbing a drink of water, but drinking plain water isn’t exciting until now.
The Define Bottle offers a straightforward, wholesome way to make drinking water even more exciting. You can bring fruit-infused water everywhere you go with this water bottle, which is gorgeous and sleek.
All you need to do is chop up some of your favorite fresh fruits and place them in the lower chamber. The upper chamber can then be filled with water. The fruits do not enter the mouthpiece since they are contained within their chambers.
A pleasant aftertaste will remain after the fruit has been infused with its flavor for between 15 and 20 minutes. You can spice up your routine while benefiting your health using Define Bottle.

Carter Kostler came up with the idea for the Define Bottle, a container allowing you to flavor your water with fruit. Can he reach an agreement with the Shark Tank investors?
Define Bottle is a delicious and nutritious way to stay hydrated during the day. Carter, now fifteen, came up with the idea for the Define Bottle when he was thirteen years old.
The company Define Bottle generates revenues of $65,000 over four months. They have a storefront website in addition to retail outlets. He made unsolicited calls to Whole Foods and DAVIDsTEA to negotiate terms for entering the stores.
In three hours, they made a $1,000 profit by selling bottles at Whole Foods Farmers Market. The Define Bottle has a suggested retail price of $30, under $10. They have a producer in China who asserts that they will bring the cost down to $5 if they work hard enough.
How Was The Shark Tank Pitch Of Define Bottle?
Carter appeared on Shark Tank seeking an investment of $100,000 in exchange for a 20% stake in Define Bottle. Carter proposed Shark Tank, asking for an investment of $100,000 in exchange for a 20% stock stake.
We want to explore this chance to persuade Americans, especially children, to drink more water by flavoring the water with fresh fruit, as the average American consumes one to two sodas daily.
Since Carter first put the Define bottle on the market, he has generated sales of $65,000 in four months. A combination of sales made online and at wholesale levels.
The Define bottles have been presented at a retail price of $30, with a cost of $10, a significant margin for each unit. This has led to introducing the Define bottles at big chains such as Whole Foods and David’s Teas.
He negotiated a price of $5 per unit for the product after speaking with a Chinese manufacturer. The website receives 2,000 hits daily, and the conversion rate is at 0.5 percent.
Barbara Corcoran is concerned that he spent far too much money on development and that she will not be able to recoup her investment. She has departed.
Kevin O’Leary is leaving because he believes there is too much competition, which is the primary reason for his departure. Lori Greiner was out due to competition from other competitors.
Robert Herjavec is confident that he has created a fantastic design, yet the shop did not reorder his product. He informs him that they need to perform some research first but that he will give him an offer of $100,000 in exchange for a forty percent equity stake in the company.
They have an investment of $85,000 in tooling and an inventory of $150,000, and they anticipate having sales of $200,000 this year. The Kostlers think that the business should be valued somewhat higher.
According to Carter, they anticipate that their sales will total $400,000 the following year. Carter asks Robert to contribute 30 percent. Robert walks away after deciding that he will not accept his counteroffer.
Mark Cuban believes nobody will tell him at fifteen, but he acknowledges that it is a “nice product.” Mark is looking for a justification to agree with you and say yes. He can’t work at the company because he has not provided sufficient background information about it, and his parents have applied for a mortgage on their house.
Final Deal: No deal between Define Bottle and Sharks.
What Happened To Define Bottle After Shark Tank?
You can still find Define Bottle being sold, and it appears to be doing rather well in terms of sales; not only is the product available on Amazon and the website specifically dedicated to the Define Bottle, but the price has also been significantly reduced.
The Define Bottle is available in seven sizes, including a 7-ounce bottle, 12-ounce bottle, 16-ounce bottle, and a 17-ounce bottle, for $16.93.
You can find Define Bottle on Amazon and get one for yourself. You can still purchase the 16-ounce Define Bottle for $20.99 directly from their site or get it for $15.99 when purchased from Amazon, which qualifies for free shipping.
350 customer reviews for the Define Bottle gave it an average rating of 3.5 stars, indicating that patrons are satisfied with the product.
Kostler appeared on HSN in July 2015 after appearing on Shark Tank. He sold all of the Define Bottles there. Kostler joined the United States Marine Corps in the summer of 2016, and at the same time, he introduced a new product called Mason Infuser via a Kickstarter campaign the same year.
You can purchase a Define Bottle from Amazon and get free shipping for two days if you have Amazon Prime. Define Bottle is more affordable, coming in at under $25, making this a superior purchase.
Kostler stated in an interview from 2017 that “Entrepreneurship is in my blood, even if neither of his websites is active.

In the first episode of Beyond the Tank, which aired in May 2015, Carter returned to Shark Tank. Carter demonstrated to the other investors how far he’d come, even without the Sharks’ money, using the Define Water Bottle as an example of a successful business.
Carter sold his company and joined the United States Marine Corps instead of remaining in business. He remains a reservist in the Amphibious Assault Vehicle Fleet.
Carter quickly got back on track and is now “making sure” that the Define Water Bottle is profitable, despite having suffered a catastrophic setback to his business when he didn’t secure a Shark Tank deal.
Carter’s product was a big hit with the audience both during and after the show ended, despite being unable to close a deal with any of the Sharks. Mark, Carter’s dad, remarked that they received more than one hundred thousand visitors to their website on the first weekend after Episode 516 was broadcast for the first time.
Also, he claimed they generated more than $225,000.00 in revenue during that time, which is nearly the same valuation Robert Herjevic gave the enterprise while he was on the show.
The young entrepreneur, who is now 16 years old, received a significant boost after his product appeared on Shark Tank and became an overnight success, but he didn’t rest there and made cold calls to giant retail shops. You can now purchase Define Water Bottles at Dick’s Sporting Goods and most of Target’s retail locations.
However, Define Bottle could not last long after its appearance on Shark Tank and is currently out of business. The valuation of Define Bottle when it appeared on Shark Tank was $500,000. The current net worth of Define Bottle is effectively $0 as the company is out of business.
