Dave Mayer walked into the Tank in Season 3, Episode 1 in the episode that aired January 20, 2012, bringing their Oakland, CA business with them. The Clean Bottle, the water bottles, pitched in the Food & Drink category, one of 318 food & drink businesses to brave the Tank across all 17 seasons.
On the carpet, the number was $60,000 for a 5% stake, which valued the company at $1.2M.
Mark Cuban made the deal at $60,000 for 8% equity. That priced the company at $750K, a haircut from the $1.2M the founders walked in asking for, which is how negotiations in the Tank usually go.
The Clean Bottle was one of 60 businesses to pitch in Season 3, where 28 deals got done. In the Food & Drink category overall, roughly 61% of pitches have landed a shark across the show's history.
The full story
Everything to know about The Clean Bottle
The Clean Bottle solves a small but real annoyance: the bottom of most reusable water bottles is impossible to reach, so it traps grime, mold, and stale residue. Founder Dave Mayer designed a bottle that unscrews at both the top and the bottom, so the whole inside opens up for easy cleaning and drying. A cyclist and triathlete from the Oakland area, Mayer built the product around an everyday problem he kept running into himself.
Mayer asked the sharks for 60,000 dollars in exchange for just 5 percent, a confident, low equity offer that signaled he already had momentum. He came in with strong sales numbers, which got the room's attention. Mark Cuban liked the product and the traction and made a deal at 60,000 dollars for 8 percent, a small bump in equity that kept Mayer firmly in control of his company.
The Clean Bottle stood out because it fixed an obvious flaw nobody else had bothered to solve cleanly, and because Mayer paired a simple idea with real distribution. The two open ends design was easy to demonstrate and easy to remember, which made it a natural fit for retail shelves and for the post show sales surge that followed.
Where The Clean Bottle is now
Mark Cuban's endorsement and the national exposure pushed sales sharply higher, and the brand expanded well beyond the original plastic bottle into stainless steel bottles, tumblers, mugs, and infused water designs. The wider lineup helped Clean Bottle move from a single clever product into a broader hydration brand sold through its own site and major retailers.
The company changed hands over the years, with reported ownership moves to a private investment firm and later to another buyer, and it continues to sell under a refreshed identity tied to the Clean Hydration name. As of 2026 Clean Bottle products remain available, making it one of the Season 3 deals that kept going long after the episode aired.
Where to buy The Clean Bottle
Clean Bottle bottles and related drinkware are still sold today through the brand's official channels and various online retailers, now under its updated Clean Hydration branding. You can expect the signature design that opens at both ends for thorough cleaning, plus expanded options like stainless steel bottles and tumblers. If you have ever given up scrubbing the bottom of a narrow bottle, it remains a genuinely practical buy, and the two open ends still make it noticeably easier to keep clean than a standard reusable bottle.
