Cave Shake aka Space Shake: A Health-Focused Keto-Friendly Product
Cave Shake, as seen in Season 10 of Shark Tank, is a high-fat, low-carb, ready-to-drink shake tailored for individuals following the ketogenic diet.
The shake is gluten-free, dairy-free, and sugar-free and is designed to support ketosis without compromising on taste or nutrition.
Cave Shake is distinguished by its focus on health-conscious consumers. The bottles are packed with medium-chain triglycerides (MCTs) for quick energy conversion, making them suitable for keto enthusiasts.
The shakes, made with organic coconut milk, not only provide a creamy texture but also use monk fruit extract as a natural sweetener, perfect for guilt-free indulgence.

Cave Shake offers flexibility across dietary preferences and lifestyles to fit various dietary preferences and hectic schedules. You will find a range of flavors to suit every taste, including chocolate, vanilla, and banana.
Cave Shake expands its product line to include plant-based protein shakes crafted with pea protein, almond milk, coconut cream, and natural flavors.
These vegan-friendly, gluten-free, and dairy-free shakes provide a convenient and nutritious option for supplementing protein intake and promoting a healthy lifestyle.
Cave Shake provides 20 grams of plant-based protein per serving and caters to athletes, fitness enthusiasts, and anyone looking to increase their protein intake. They are low in sugar and calories yet provide essential nutrients like vitamins, minerals, and fiber.
Free from artificial additives and common allergens like soy and GMOs, Cave Shake prioritizes quality ingredients to meet diverse dietary needs.
Whether enjoyed as a quick snack or customized into smoothies, these shakes provide a delicious and allergen-free protein source for a wide audience.
Cave Shake was founded by Holly Heath and Billie Cavallaro out of a shared love of healthy eating and a ketogenic lifestyle.
Combining culinary expertise with business acumen, the founders sought to fill a gap in the market for satisfying yet health-conscious snacks aligned with keto and paleo diets.
Prior to their Shark Tank appearance, Cave Shake had garnered positive reviews for its taste, nutritional value, and ability to cater to dietary restrictions.
The founders’ goal of securing a strategic partner aligns with their mission to expand the brand’s reach, enhance production capabilities, and sustain its growth trajectory in the competitive health food industry.
The Evolution of Cave Shake: From an Idea to Shark Tank
The Cave Shake presentation on Shark Tank was engaging, featuring personal anecdotes, detailed product information, and a catchy theme song.
Holly Heath and Billie Cavallaro, the founders, sought a $250,000 investment for a 10% equity stake in their business, valuing Cave Shake at $2.5 million.
The founders began by discussing the challenges of following a low-carb, ketogenic diet and how Cave Shake offered a delicious and satisfying solution.
They emphasized the product’s versatility, highlighting its suitability as a pre or post-workout snack, meal replacement, or dessert.

Cave Shake stood out for being low in carbohydrates and rich in Medium Chain Triglycerides (MCTs), providing quick energy.
During the tasting session, the Sharks had mixed reactions to the product. While Robert Herjavec found the taste unfavorable, Mark Cuban and Lori Greiner, who were seasoned in trying various diets, seemed to enjoy it.
Questions were raised about the high-calorie content per serving (480 calories). The founders clarified that in a ketogenic diet, the focus lies more on maintaining a low-carb, high-fat intake rather than calorie count.
Cave Shake had generated $270,000 in sales the previous year and had reached $182,000 in sales for the current year at the time of filming.
However, the Sharks expressed reservations regarding the founders’ prior partnership with LA Libations, an incubator linked with Coca-Cola.
Mark Cuban criticized the founders for giving up 15% of the equity in return for resources and support.
Kevin O’Leary and Robert Herjavec opted out of the deal due to concerns about the business strategy and their lack of familiarity with or preference for the keto diet.
Mark Cuban appreciated the entrepreneurs and their products but backed out, citing the investment’s demanding nature.
Lori Greiner withdrew her interest, citing a preference for not consuming liquid calories.
Guest Shark Charles Barkley proposed the $250,000 investment for a 20% equity share, double what the founders initially requested.
After a brief negotiation where the founders tried to reduce the equity to 14%, they accepted Barkley’s offer. Barkley shared his weight struggles and his interest in supporting health-promoting products as his motivation for the deal.
Following their appearance on Shark Tank in 2023, the company successfully raised $750,000 and rebranded as Space Shake.
With assistance from their incubator, LA Libations, they secured shelf space in Whole Foods and addressed the Sharks’ concerns about high-calorie content by reducing it to 180 calories per serving in a redesigned pouch.
Final Deal: Charles Barkley agreed to invest $250,000 for 20% equity in Cave Shake.
From Cave Shake to Space Shake: Growth and Innovation After Shark Tank
After their appearance on Shark Tank, Cave Shake experienced significant growth in their business operations.
Cave Shake sealed a substantial $750,000 deal with guest Shark Charles Barkley and decided to rebrand as “Space Shake” to emphasize its commitment to promoting a healthier lifestyle.
Space Shake’s website showcases their portable meal replacement shakes in 3.4-ounce pouches, available in vanilla, chocolate, and coffee flavors. You have the option to purchase six or twelve-pack cases of these pouches.
The product is also available in states like Nevada, Missouri, and New York, as well as locations throughout California.

Space Shake successfully entered the Whole Foods market by leveraging its strategic alliance with LA Libations. They were able to increase their visibility as well as broaden their customer base by doing this.
In response to feedback from the Sharks regarding the high-calorie content of their shakes, Space Shake adjusted the serving size, reducing the calorie count from 480 to a more manageable 180 per serving.
This adjustment made their product more appealing to health-conscious consumers. Additionally, they redesigned the packaging for greater convenience, now offering the shakes in easy-to-carry pouches.
Customers can also buy the low-carb shakes on Amazon, as highlighted in one of their Instagram posts.
The initial success of Cave Shake, including partnerships with L.A. Libations and Whole Foods Market, laid a strong foundation for the growth and popularity of Space Shake.
The rebranding and investment from Charles Barkley have further fueled the company’s expansion and success.
Cave Shake, aka Space Shake, is still in business and has an estimated net worth of $5 million. The valuation of Cave Shake was $1.25 million after securing an investment from Charles Barkley on season 10 of Shark Tank.
In summary, the transformation from Cave Shake to Space Shake following their appearance on Shark Tank, coupled with securing significant investment and implementing feedback for improvement, has propelled Space Shake towards a positive trajectory in the market. The company’s expansion and success post-Shark Tank demonstrate their commitment to growth and innovation.
