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.
Garrett Waggoner is the co-founder and CEO of Cirkul, the Tampa-based hydration company whose reusable bottle and flip-dial flavor cartridges turned a college locker-room frustration into a business valued at $1 billion. A former Dartmouth safety who played professional football in the CFL and worked as a car valet to bootstrap the idea, Waggoner built Cirkul into a roughly $378M-revenue, 800-person operation by insisting on owning its own manufacturing.
