Poppi's Founders Launch Jetty, a Cleaner Play for the $40B Hydration Aisle

Allison and Stephen Ellsworth, who sold probiotic soda brand Poppi to PepsiCo last year for $1.95 billion, are launching their second act: Jetty, a hydration drink aimed squarely at everyday consumers in a $40 billion electrolyte category still ruled by Gatorade and Powerade.

The public debut marks a fast return for a founding duo whose first company began, quite literally, at the kitchen counter. Allison Ellsworth, 39 and a mother of three boys, struggled to stay hydrated and routinely tore open electrolyte powder packets, mixing them with water and, in the process, making a mess. Her husband Stephen started blending his own hydrating beverages for her at home.

At some point, the pattern became obvious. Ellsworth looked at her husband and said: "Oh my god, we're doing this again, aren't we?"

Indeed they were. The Ellsworths went on to build Poppi, the probiotic soda they started in their kitchen and sold to PepsiCo for $1.95 billion. That exit — roughly $2 billion by the round numbers the trade press prefers — is the strongest validation a beverage founder can carry into a sophomore launch. It also sets the bar uncomfortably high.

What does Jetty actually sell?

The product positioning is clean-label simplicity. Jetty contains only 6 grams of sugar and 45 calories per serving. The formulation uses no artificial colors and no artificial sweeteners. In a hydration aisle crowded with neon legacy products, that spec sheet is the pitch.

The target buyer is not the marathoner or the elite athlete. Jetty is positioned for everyday consumers — parents, busy households, people who want hydration without the powder packets and the sticky counter. That's the same mainstream instinct that made Poppi a billion-dollar asset rather than a niche health-food fixture.

Why the $40 billion electrolyte market?

The category math is straightforward. The electrolyte drinks sector is worth roughly $40 billion, and it remains dominated by legacy brands: Gatorade and Powerade, both owned by beverage giants with decades of shelf power and sports-marketing budgets. That's the opportunity and the threat in one sentence.

Challengers have been chipping at that dominance for years, and functional-drink upstarts with cleaner labels have repeatedly taken share from incumbents. Poppi proved the Ellsworths can execute that playbook once — prebiotic soda against traditional cola, cleaner ingredients against a legacy formula. Jetty attempts an encore, with electrolytes against the sports-drink establishment.

What does this change for retailers and marketers?

For buyers, Jetty adds another founder-led, clean-label challenger to a hydration set already thick with them, and the Ellsworth name carries retail credibility that most startups spend years earning. For CPG marketers, the launch confirms that the post-exit founder brand is becoming its own growth strategy: build, sell for near-$2 billion, and re-enter an adjacent category with the audience and the playbook already in hand.

The open question is whether the Poppi halo transfers to a category where Gatorade's brand equity runs decades deep. The Ellsworths have bet $1.95 billion worth of reputation that it does.
