The Businesses and Products from Season 18, Episode 3 of Shark Tank
In season 18, episode 3 of "Shark Tank," entrepreneur, investor and "Dragons' Den" Dragon Steven Bartlett makes his guest Shark debut. Passionate business owners pitch an anchored leash for dogs, an electrolyte-rich cashew milk, an on-the-go hydration pouch and a disposable heated vest. Get the full details on the companies featured below.
Pup Stack
The Pup Stack is a portable dog anchor that can be used on any surface—indoors or out, at home or on the go. Its 20-foot retractable tie-out line locks at any length, while built-in storage and food and water bowls keep essentials close at hand. The 360-degree rotating design helps prevent tangles, and its expandable base allows owners to add weight as their puppy grows. The Pup Stack is recommended for most dogs up to 40 pounds.
Nutcase
Nutcase is the first ever electrolyte milk. Made with rich creamy cashews & real clean ingredients, packed with potassium & magnesium, and only 5g of sugar. Backed by gamer Ninja & DJ Steve Aoki, Nutcase is the ultimate guilt-free dairy-free late-night sweet fix. It's nostalgic, functional and designed to help with recovery, cramping & bloating. We've given you the freedom to enjoy chocolate milk again.. and be a total nutcase.
UnderWarmer
The UnderWarmer is a body warmer -- Air-activated, no batteries, no charging. Delivering up to 12 hours of heat; it's a super affordable, convenient alternative to expensive heated gear. Simply open it, put it on, and Stay Warm. All Day!
Fundelivered
Fundelivered transforms excess retail inventory into moments of surprise and fun, offering customers a mystery box experience where no two boxes are the same. Each box contains a randomized assortment of home, beauty, fashion, lifestyle, and totally unexpected retail goods, individually wrapped to create the thrill of never knowing what you will open next. The idea began after the founders, Rebecca and Jena, ordered a pallet of unclaimed items and excess retail goods. Watching friends laugh, trade, and enjoy the experience so much inspired them to turn that moment into a business centered around joy, connection, and a greener approach to retail by helping keep perfectly good products in circulation rather than letting them go to waste. Fundelivered has since grown into a national brand known for lively group unboxings, viral online moments, and a customer base that loves the excitement of the unknown.
ZALT
ZALT is the first-ever electrolyte + B vitamin oral pouch, designed to make hydration support more convenient, portable, and fun. Each pouch fits discreetly under your lip—no water bottle, powder, or mixing required. Founded by friends Sam Mitchell and Dominic Gozza, ZALT is built for people in motion, delivering hydration support that moves with you wherever you go.
