Stephen Ellsworth
Co-founder
Stephen Ellsworth co-founded the prebiotic soda brand Poppi alongside his wife, Allison, turning a homemade health remedy into a global beverage powerhouse.
After a transformative appearance on Shark Tank, Stephen helped lead a total brand overhaul that turned their original concept into the vibrant Poppi identity. He was instrumental in pivoting the company to a digital-first strategy during the 2020 lockdowns, utilizing clever e-commerce and affiliate data strategies to break sales records on Amazon. This tech-savvy approach allowed the brand to find a massive audience in middle America well before it dominated coastal hubs.
Stephen’s leadership culminated in bold moves like a last-minute Super Bowl ad that tripled brand awareness and drove annual revenue past $500 million. In 2025, he and Allison achieved a landmark exit by selling the company to Pepsi for nearly $2 billion. Stephen now serves as an advisor.
