If you were a fan of Shark Tank, you might remember Cave Shake, the keto-friendly, ready-to-drink shakes that promised a delicious and healthy way to stay on track with your diet. The founders, Holly Heath and Billie Cavallaro, walked into the tank with high hopes and walked out with a deal. But where are they now? Let’s take a look at their journey and how things turned out after the show.
The Beginning of Cave Shake
Cave Shake started in 2015, born out of a need for a tasty, keto-friendly snack that was both dairy-free and packed with healthy fats. Holly and Billie wanted something that fit their active lifestyles without all the sugar and carbs found in typical drinks. The product gained traction among health-conscious consumers, especially in California, where the keto lifestyle was booming.
Cave Shake Shark Tank Pitch
In 2018, the duo appeared on Shark Tank in season 10, episode 4, asking for $250,000 in exchange for 10% of their company. After some negotiation, they landed a deal with Charles Barkley, who invested $250,000 for 20% equity. The exposure was huge, and for a while, it seemed like Cave Shake was on the path to becoming a household name in the health food space.

A Major Rebrand
After Shark Tank, the company decided to shake things up—literally. They rebranded Cave Shake to Space Shake, a name they felt was more modern and appealing to a wider audience. Along with the new name came new packaging and a tweak to the formula, reducing the calorie count to 210 calories per serving. The new look was sleek, and they positioned themselves as a healthy, grab-and-go snack for busy people.
How Much Is Space Shake Worth Now?
As of early 2025, Space Shake’s estimated net worth is around $10 million. They reportedly generate about $3 million in annual revenue. That’s a solid number for a niche health product, but it’s not quite the explosive growth many Shark Tank fans expected.
Life After Shark Tank – Where Are They Now?
The exposure from Shark Tank helped Space Shake get into more stores, including Whole Foods, and they even partnered with LA Libations, a company known for scaling beverage brands. They also shifted their packaging to soft pouches, which made them easier to transport and store.
But despite these positive changes, the brand’s momentum seemed to slow down. Their social media pages haven’t been updated since October 2022, leaving fans wondering if they’re still actively pushing the brand forward.
Adding to the uncertainty, co-founder Billie Cavallaro left the company in December 2020, leaving Holly Heath as the sole leader. This kind of change can be tough for a small business, especially in such a competitive market.

What Could Have Gone Wrong?
Even with a great product, the health food space is crowded with competition. New brands pop up every day, and staying relevant requires constant marketing and innovation. Space Shake had a unique selling point, but without continuous engagement and expansion, it’s easy for customers to move on to the next big thing.
Another challenge could have been the rebrand itself. While “Space Shake” sounded cool, some loyal customers might have been confused or put off by the name change. Building a brand identity takes time, and rebranding can sometimes disrupt that connection with consumers.
The Future of Space Shake
Right now, it’s unclear what’s next for Space Shake. They still have a presence in some stores, but their lack of online activity raises questions. Are they planning a comeback, or have they quietly moved on to other ventures?
Regardless, their journey is a great example of how even a successful Shark Tank pitch doesn’t guarantee long-term success. Running a business takes constant effort, and sometimes, things don’t go as planned.
Whether you’re an entrepreneur looking for inspiration or just curious about what happened to your favorite keto shake, the story of Cave Shake (now Space Shake) is a fascinating one.
