Sub Zero is an innovative ice cream parlor using cryogenics with liquid nitrogen to create custom-made ice cream per person, addressing limitations in traditional parlors. The made-to-order process offers numerous customizable options, including vegan, sugar-free, yogurt, reduced fat, and original ice cream bases, with hundreds of flavor combinations. Founded out of necessity, the business originated from a New York Burrito franchise, evolving into a unique dessert concept in 2005. With a patented freezing process, Sub Zero expanded through franchising from 2008, gaining exposure on “Shark Tank” in 2013. Despite not securing a deal, the show contributed to the company’s growth, currently boasting a successful and memorable ice cream experience.
