On Season 10, Episode 4 of “Shark Tank” in 2018, business partners Billie Cavallaro and Holly Heath pitched their business Cave Shake, a keto-friendly meal replacement milkshake. They asked for $250,000 for 10% of their business, and NBA star Charles Barkley offered $250,000 for 20%, which they accepted happily.

After accepting Barkley’s offer, Cavallaro and Heath rebranded their popular product and changed their company name to Space Shake. The retail locations tab on their website shows numerous locations in California, while also expanding across the U.S. to states like Nevada, Missouri, and New York. The company even sells its product on Amazon.

On the Space Shake website, fans can purchase either six or 12-pack cases of the 3.4-ounce pouches that come in three flavors: vanilla, chocolate, and coffee. While there may be hidden dangers of the keto diet, it hasn’t stopped Space Shake from jumping in popularity and spreading through Southern California and beyond.
