Shark Tank Coldest Pitch

• Entrepreneurs: David Stark and Joe Wayne
• Business: A line of cooling products
• Ask: $600,000 for 2% equity
• Result: No deal
• Shark: None

Twin brothers David and Joe entered Shark Tank to pitch Coldest, their drinkware line designed to keep drinks and other items cold for longer periods.

They launched the company in Naples, Florida, where the intense heat pushed them to create something better than the water bottles already on the market.

Their flagship product, the Coldest Limitless Series Bottle, keeps drinks cold for up to 36 hours.

It’s designed to be leakproof, has a wide-mouth opening, comes with three interchangeable lids, and features a non-slip rubber bottom for stability.

To prove its performance, the brothers told the sharks they tested their bottle against over 50 major hydration brands. Coldest outperformed them all.

In addition to their drinkware, they expanded into other “cold” lifestyle products. These include the Coldest pillow, the Coldest dog bed, and the Coldest dog bowl.

As the sharks examined the sample products on the table, David and Joe shared more about their background.

They grew up with two engineer parents, with their dad being from Jordan and their mom from the Philippines. They assumed they’d follow the same path.

However, after trying and failing at several software and e-commerce ventures, they launched Coldest in 2015.

David started with $14,000 of his own savings. He ordered 1,000 bottles from a factory, then panicked, unsure if they could sell in such a competitive space. But by then, it was too late to cancel.

It took five months to sell the first batch on Amazon. Joe joined full-time in 2017, focusing on marketing while David handled the product.

In terms of sales, 2019 brought in $5.9 million, while 2020 brought in $9.3 million. In 2021, sales were $12.4 million, and in 2022, sales were $15.1 million.

However, despite $15.1 million in sales, they lost $400,000.

Looking ahead, they projected $22 million in sales for 2023. But inventory remained a challenge; they couldn’t produce fast enough to meet demand.

In terms of cost, the Coldest Limitless Series Cup retails for $55.99. The brothers manufacture each unit for $10 to $12.

The sharks reacted with mixed feelings.

Lori Greiner said the product was strong, but the inventory problem was too risky. She went out.

Mark Cuban liked their branding but lost interest when they revealed they spent over $3 million on ads last year. He also went out.

Robert Herjavec struggled to understand how a company making $15 million could still lose money. He passed too.

Daymond John said the constant reinvestment made the business hard to manage. He decided not to invest.

Kevin O’Leary made the only offer. He offered $600,000 for 7% equity, with a $2.25 royalty per unit until he earned back $3 million.

Joe countered with a $600,000 loan to be paid back at $900,000 in 3–5 years. Kevin declined.

The brothers countered again with $1.5 million for 5% equity, plus a buyout option at 1.5X after three years. Mr. Wonderful stuck to his original terms.

Ultimately, the brothers turned down the deal and walked out without an investment.

Shark Tank Coldest Update

In terms of a Coldest update, we found that shortly after their Shark Tank appearance, they cut nearly 80% of their SKUs, removing pillows, pet beds, ice packs, and flavor drops from their store.

The founders said this was a direct result of their post Shark Tank feedback and part of a larger plan to channel their focus on their best seller (The Coldest Water Bottle).

Around this time, they also launched a massive closeout sale to clear excess inventory.

Later in 2024, the company relocated to a 52,000 sq ft facility in Fort Myers, Florida, giving them room to expand operations and improve logistics.

In April 2025, they announced they had become completely debt-free, having eliminated around $4 million in debt through restructuring and discipline.

They also downsized to a 30-person team and began working with multiple manufacturers, both in the U.S. and abroad.

At the time of this writing, the company now focuses entirely on bottles and is preparing to launch five new coffee-related products as part of a thermal drinkware line.

Meanwhile, they’ve even teased plans for a Coldest theme park by 2030.

The company’s current hero product, The Coldest Water Bottle, is available in multiple sizes, including the 46 oz Limitless Series, which they claim keeps drinks cold for 36+ hours or hot for 13+ hours.

Bottles retail between $25 and $50, depending on size and customization. They also run weekly giveaways and maintain a VIP Facebook group with over 38,000 members.

If you need a water bottle that stays cold for hours, order directly from their website. You can also follow them on Instagram for product drops and giveaways.

We’ll keep watching their journey. If there’s more to report in a future Coldest update, we’ll let you know.
