Stan Efferding is a professional bodybuilder, not a typical consumer-products founder, and the Kooler was built around a very specific gym-and-outdoors problem: an insulated cooler with built-in drink shakers, so you could mix a protein shake or a cocktail on the go without carrying separate gear. It had a genuinely strong launch. It did not have a lasting business behind it.
The Short Answer
No, the Kooler is not in business anymore. Multiple sources tracking the company's history confirm it closed in 2021, citing production challenges as the cause, roughly five years after its Season 8 appearance. If you found this page hoping to still buy one, the honest answer is that you cannot, at least not from the original company.
This is one of the clearer defunct verdicts in this batch. The closure is not a rumor pieced together from an inactive website, it is a directly reported shutdown with a specific cause attached.
The Shark Tank Pitch
Efferding pitched in Season 8, Episode 15. He asked for 50,000 dollars for 15 percent equity, framing the Kooler around the fitness and outdoor recreation crowd he already had credibility with as a competitive bodybuilder.
Only one shark bit, and it was not an easy sell. Daymond John was the sole investor to make an offer, which is worth noting given how strong the product's early sales momentum turned out to be.
The Deal That Got Done
Daymond offered 50,000 dollars for 33 percent equity, more than double the 15 percent Efferding originally asked for. Efferding accepted, giving up a substantial chunk of the company for the same dollar amount he pitched for.
That is a steep equity trade even by Shark Tank standards, and in hindsight it looks worse than it did on air, given how the company's story ended. Daymond's retail and consumer products background made him a logical partner on paper, but even strong distribution muscle could not carry the Kooler through its production problems.
A Strong Launch That Could Not Solve Its Manufacturing Problem
The Kooler's post-show run actually started well. The product reportedly sold out its inventory on HSN and expanded into physical retail stores, real signals of consumer demand following the television exposure. That kind of early sellout is exactly the outcome every Shark Tank founder hopes for.
The trouble was on the supply side, not the demand side. Sources describe the company running into ongoing production challenges that it was ultimately unable to resolve, and by 2021 those problems had caught up with the business enough to force a full closure. That is a familiar pattern for physical products with a somewhat complex build, an insulated cooler with an integrated shaker mechanism is more manufacturing-intensive than a simple single-material product, and a company can sell through its inventory faster than it can reliably restock at scale. The Kooler appears to have hit exactly that wall and never recovered from it.
Kooler net worth in 2026
There is no net worth figure to report for the Kooler in 2026 because the company does not exist anymore. A closed business generates no ongoing revenue and holds no meaningful going-concern valuation beyond whatever assets, if any, remained at the time it shut down, and no information on that is publicly available.
Stan Efferding remains active and known in the bodybuilding and fitness world independent of the Kooler's fate, but there is no credible source attributing a specific net worth figure to him from this particular venture. Anyone claiming a current dollar value for the Kooler brand itself is not working from real information.
Where Things Stand Now
The Kooler pitched in Season 8 out of the fitness world Stan Efferding already knew well, asked for 50,000 dollars for 15 percent, and gave up 33 percent to Daymond John for that same amount.
It sold out on HSN, expanded into retail, and then ran into production problems it never solved, closing for good in 2021. If you are here wondering whether the shaker-cooler from Shark Tank made it, it did not, and it has been gone for roughly five years now.
