Allison Ellsworth.

Allison Ellsworth became one of the most recognizable consumer brand founders of her generation.

Known to millions on TikTok as 'the Poppi girl,' she pioneered a creator-led approach to brand building that turned her into the face of Poppi and helped the prebiotic soda achieve a level of viral growth that traditional CPG marketing could not have produced. She developed the original apple cider vinegar formulation in her kitchen, survived a Shark Tank pitch that initially went sideways, and then rebuilt the brand under the Poppi name with her husband Stephen. The brand's irreverent visual identity and Gen Z-native storytelling created a template competitors have struggled to copy. PepsiCo acquired Poppi in 2025 for roughly $1.95 billion. Ellsworth was named a 2025 EY Entrepreneur of the Year Consumer Products and Retail Award winner. Her combination of product instinct, personal brand building, and retail execution represents a new operating model for how American consumer brands get built now - one where the founder is the distribution channel, and the product has to live up to the attention the founder can generate.
