Cirkul
Cirkul is a Tampa-based personalized hydration company that makes a reusable water bottle paired with snap-in flavor cartridges and a 'Flavor Dial' that lets drinkers control how much taste, vitamins, electrolytes or caffeine flow into plain water - with zero sugar and zero calories. Founded by former Dartmouth football teammates Garrett Waggoner and Andy Gay, the brand went viral on TikTok, became one of Walmart's fastest-selling home products, and reached a $1 billion valuation.
Hint Inc.
Hint Inc. makes unsweetened, fruit-infused water with zero sugar, zero sweeteners, and zero calories. Founded in San Francisco in 2005 by Kara Goldin, Hint grew from a personal health experiment into the #1 unsweetened flavored still water brand in the U.S. The company sells over 25 flavors through major retailers like Whole Foods, Target, Walmart, and Costco, as well as directly through its website — where DTC now represents more than 50% of revenue. With $91M+ raised and an annual revenue of approximately $143M, Hint has quietly built one of the most compelling better-for-you beverage brands in America.
