Entrepreneurs often need a chance to step into the spotlight and help their businesses flourish, which is how ABC’s ‘Shark Tank’ helps them. It provides the founders with a platform to pitch their business and convince a panel of seasoned investors to back their visions. In season 18, episode 3, appropriately titled ‘Diary of a Shark,’ the attention shifts to four distinct brands: Pup Stack, Nutcase, ZALT, and UnderWarmer. Each of the brands’ founders arrives with a different story, hoping to establish a prominent position for their venture in the market.
Pup Stack is Giving Dogs More Freedom With Its Portable Tethering Product
The story of Pup Stack began when the wife of its inventor, Brian Zibricky, was suddenly diagnosed with multiple sclerosis, and he brought home a pup named Cooper to keep her company. However, when it became hard to control Cooper, Brian created Pup Stack and filed for a patent on it on September 14, 2022. The product was ultimately patented on August 12, 2025. It is a portable dog anchor with a 20-foot tie-out line, additional storage for treats, water, and toys, and 360-degree rotation. The product is also easily expandable up to 40 lbs. Customers can easily purchase Pup Stack in black, pink, or white for just $124.99. Additionally, the brand offers Pup Stack Weight for $19.99, alongside Pup Sticks.
Customers can also purchase the Pup Stack Plush Toy combos for $22.49, and the single Plush Toys are priced at $14.99 each. Beyond that, Pup Stack has remained active on Instagram, where the brand showcases the mechanism of its star product in everyday settings. It often shares customer reviews and product demonstrations. In August 2026, Brian revealed that a customer from Florida was randomly selected to receive the free Pup Stack Plush inside their package. By September, two other customers were also surprised with the gifts. Moreover, the brand often highlights its commitment to quality checks, ensuring every item meets the standards.
Nutcase Has Put a Nutritious Spin on Chocolate Milk With Its Electrolyte-Rich Formula
Joelle “Jo” Weinand founded Nutcase in January 2023 after experimenting in the kitchen to create her own cashew milk. When she spontaneously created an incredibly nutritious chocolate milk, she soon began selling the product before it made its way to Las Vegas, Nevada. With the positive response, the brand attracted investors, and Jo soon connected with the gaming icon, Tyler Blevins, AKA Ninja. He eventually joined Jo as the co-founder of the venture. Today, Nutcase is known for its electrolyte-rich cashew milk. Most recently, the brand was selected to appear on ‘Going Public’ in hopes of securing investment. Customers can seamlessly purchase its 12-can cases of Cashew Milk in the flavors Chocolate Chaos, Vanilla Churro, and Japanese Strawberry at just $36.
Apart from that, Nutcase offers Cashew Milk Powder for $27, in the same flavors as the milk. The company also sells merchandise, including hats, T-shirts, and stickers, priced from around $3 to $60. They further provide wholesale purchasing options. It has built a strong relationship with its customers through the Instagram page. The platform shares product benefits, customer feedback, and creative ways to enjoy the drinks. In July 2026, Nutcase collaborated with Steve Aoki, which was followed by another partnership with DJ Astera the following month. By September, it worked hand in hand with Mark Eteson and the digital creator of the Instagram page “itskiddoi” to further highlight the popularity of its products.
ZALT Has Simplified Hydration For Active People With Electrolyte Pouches
For the founders, Dominic “Dom” Gozza and Sam Mitchell, staying properly hydrated as athletes has always been difficult. While they found the electrolyte powders to be an outdated solution, they also found drinking coconut water regularly a hassle. That eventually led them to develop the idea of an on-the-go hydration pouch. As the idea gained momentum on social media, Dom and Sam focused on researching, formulating, and having conversations with sports nutrition experts before launching ZALT. It focuses on providing a portable electrolyte solution containing electrolytes and B vitamins. Customers can easily purchase the products on the official website and on Amazon.
As of writing, ZALT offers Electrolyte Pouches in the following flavors: Watermelon, Lemon Lime, Cool Mint, and Strawberry Lemonade. Its mixed 4-pack is priced at $39.96, and the 5-pack combos are available for $44.95. Currently, the products are also available in retail stores, making them more accessible for customers. In June 2026, the brand collaborated with Gather Community during a pickleball event, which was soon followed by a paid partnership with the actor and choreographer, Victoria Joy Caro. In August, Sam was interviewed by 1800DTC, during which he spoke about ZALT’s journey. By the next month, the company expanded its lineup with Strawberry Lemonade and Lemon Lime flavors before being featured on the podcast, ‘Off The Rails With Eric And Aisha.’
UnderWarmer Offers an Easy Way to Stay Warm With Its Disposable Heated Vest
UnderWarmer was launched by two cousins, Paul and Bryan Schaefer, who set out to create a simple solution for staying warm without relying on batteries or bulky layers. It ultimately led to the creation of a disposable heated vest designed to deliver warmth via air activation. Users simply have to open the UnderWarmer and put it on themselves to let the air activation begin producing noticeable heat within just 10 minutes of wearing it. It is currently available for purchase at just $14.99 on their official site and on Amazon. The brand’s vest comes with eight large built-in heat packs that provide 12 hours of warmth.
If the users want, they can use the UnderWarmer vests for a few hours before placing them in ziplock or airtight bags to pause the heating process. They can easily reactivate it later and continue the process around two to three times before the vest becomes disposable. Furthermore, its versatility makes it quite appealing to people of all ages and sports fans, especially football enthusiasts. The brand has continued using social media, including Facebook and Instagram, to showcase its product and demonstrate how it can be used in everyday situations. However, it is essential to note that UnderWarmer hasn’t been very active recently.
