Coldest Water Bottle Shark Tank: The Pitch and Outcome
The Coldest Water Bottle made a splash on Season 15, Episode 15 of Shark Tank. Brothers David and Joe Ahmad showed off their product to the Sharks. They wanted $600,000 for 2% of their company. This was a big moment for the Florida startup, which started in a garage and became a global brand.
During their pitch, the Ahmad brothers highlighted their sales success:
| Year | Revenue |
|---|---|
| 2019 | $5.9 million |
| 2020 | $9.3 million |
| 2021 | $12.4 million |
| 2022 | $15.1 million |
| 2023 (Projected) | $22 million |
Despite their success, the Sharks had doubts about profits. The company lost $400,000 in 2022, mainly due to $3.3 million in ad costs. This made some Sharks, like Mark Cuban, skeptical.
Kevin O’Leary offered $600,000 for 5% equity and a $2.25 royalty per unit. The Ahmad brothers valued their company at $30 million and turned down the offer. They left without a deal but with useful advice on costs and product lines.
Even without a deal, the Coldest Water Bottle is doing well. They’re set to hit $25 million in sales for 2024. This shows that Shark Tank can be valuable, even without an investment, through exposure and insights.
