A simple, cardboard kid-safe cutter, ChompShop became an overnight sensation when it landed on Shark Tank Season 16, Episode 5.

The kid-safe cutter impressed investors with its unique design, safety-first approach, and educational twist. Founders Kausi Raman and Max Liechty walked away with a $250K Shark Tank deal from Mark Cuban and Lori Greiner, showing that the right product and pitch can turn creativity into big business.

The Kid-Safe Cutter That Impressed Mark Cuban and Lori Greiner

ChompShop is a kind of cutter that kids can use to cut cardboard. It is safe to use, even if they come into contact with the blade, because it chomps the cardboard instead of cutting it.

ChompShop lets kids be creative and have fun while still keeping them safe. Kids can use it to make all sorts of 3D models, castles, or art projects without worrying about getting hurt. The ChompShop is for curious kids aged eight and above, parents, schools, and educational programs focused on STEM learning.

The founders saw a need for a fun tool like this and filled a gap that no other toy or craft tool addressed.

Founder’s Story Behind the Kid-Safe Cutter Shark Tank Pitch

Kausi Raman and Max Liechty met at the University of Pennsylvania, where they were studying product design. They both loved making things with their hands. They saw that the existing tools for kids were not good or were not safe. This made them think about making a kid-cutter that people could use without worrying.

Kausi Raman and Max Liechty faced several challenges. They had to make versions of the cutter to get it just right so it would be safe and work well. Kausi and Max bootstrapped the product development while testing the product with real families.

The fact that they were helping kids to make things safely kept Kausi Raman and Max Liechty going even when they were very tired and things were not going well at first.

Inside the Shark Tank Pitch That Won Mark Cuban and Lori Greiner

When they walked into the tank, they had a lot of cardboard with them and a demo to impress. Max showed everyone how the ChompShop can cut out shapes without hurting anyone. It is also good for kids, who can use the ChompShop with printed instructions to make their projects.

The Sharks’ reactions were instant. Mark Cuban tried the cutter on his finger. Lori Greiner thought it was really cool for kids, and also about all the fun things kids could make with it.

Kevin O’Leary said people need to know how to use it, and they told the Sharks about their STEM kits that are subscription-based. Every time they showed the Sharks something, the Sharks wanted to know more about the product and what it could do.

The $250K Deal with Mark Cuban and Lori Greiner

Raman and Liechty wanted $250,000 for 5% of their company. Mr. Wonderful offered them $250,000 for 20% of the company. Barbara Corcoran agreed with Mr. Wonderful. Rashaun Williams, a guest investor, did not want to invest. He thought the company would not make sales.

Mark Cuban said he would give them $250,000 for 15% of the company, and Lori Greiner suggested splitting it equally.

The final deal was that Mark Cuban and Lori Greiner would each get 7.5% of the company for $250,000. This brought in two experienced investors who could help the company make more products, sell them in stores, and improve marketing.

Why Mark Cuban and Lori Greiner Saw Big Potential in the Kid-Safe Cutter

The ChompShop looked into a booming market as a safe, creative tool for kids with a focus on STEM learning. It is better than other products in the market because it is fun and helps kids learn.

Mark and Lori thought the ChompShop could be a popular holiday toy and that the kids would use it all the time to learn new things.

What Happened After Shark Tank for the Kid-Safe Cutter

The deal really helped ChompShop become a known company. Pre-orders already were 10,000 units, generating over $2.1 million in sales before product delivery. Now they are working on selling their products on stores like Amazon and maybe even in stores.

The founders are also working with schools and groups that teach STEM through fun, safe, hands-on projects. People are talking about ChompShop online, particularly parents and educators who value learning tools that kids actually enjoy.
