Ryan Duey was living in an RV with his float spas closed and no backup plan when he and Michael Garrett built their first cold plunge from a retrofitted $100 bathtub in a garage. They turned their Shopify store on with zero marketing—and got a sale. What followed was one of the most unlikely scaling stories in DTC history: $30 million to $80 million in a single year, $250 million in cumulative revenue, four sharks bidding on Shark Tank, and a category they essentially created from scratch—all bootstrapped, all assembled in-house in California. In this interview, the co-founders of Plunge break down the real cost of scaling a high-ticket inventory business, why they lost an estimated $20 million in revenue from lead times alone, and the organic influencer strategy that built the brand before they ever ran a paid ad. What you'll learn in this interview: • How they got their first sale with zero marketing—and the Black Friday that showed them how big this could get • The cash flow trap every inventory-heavy founder hits: why a great P&L and an empty bank account can exist at the same time • How customer prepayments funded growth for years—and what forced the switch to holding inventory • Why long lead times cost Plunge an estimated $20 million in lost sales • From buying parts on Amazon to co-designing a custom chiller in China—the full supply chain evolution • How a single Instagram comment to Aubrey Marcus started a chain of organic gifting to Huberman, Tony Hawk, and Rich Roll • The Shark Tank deal that never closed—and why they still got the PR, the airing, and the exposure • How they bought plunge.com from a New Orleans jazz band for $250K—and why the trademark was the bigger win • Why nearly half of all orders close through a phone call or SMS, not a checkout button • How they raised $1.3 million from their own customers in under two weeks via Wefunder If you're building a high-ticket DTC brand, navigating the brutal cash flow realities of an inventory-heavy business, or trying to grow without burning cash on paid ads before you're ready, this conversation will fundamentally change how you think about scaling, supply chain, and what it actually takes to build a category from a garage.
