​Hi, I’m Lindsay O'Keefe (formerly O’Neill )— Founder of Small Hinges LLC, CEO of Wellness Eternal, TEDx Speaker, Harvard-Certified Culinary Medicine Chef, and host of the #1 podcast Optimize W(e). Recognized by MSN and NY Weekly Magazine as a Top Female Entrepreneur and Biohacker in 2025, I contribute regularly to Forbes, Entrepreneur.com, Business Insider, Women's Health Magazine, Global Woman Magazine and more. With over 20 years as an AI and Machine Learning technologist, I bring a rare blend of data-driven strategy and human optimization to the world of wellness and longevity.

​

My career began in AdTech and Big Data, where I built platforms that automated billions of decisions in milliseconds. But after facing a chronic inflammatory illness, I turned that same data-driven mindset inward—seeking diagnostics, biohacking tools, and integrative solutions to restore my health. That journey led me to the TEDx stage with The Data Driven Journey to Optimal Health and to Gaia, where I shared my story of resilience, science, and health-optimization.

​

In 2024, I launched Wellness Eternal (WE) to bring efficacy, trust, and clarity to the crowded biohacking and longevity space. A year later, we introduced the Biohacking Index —the first platform of verified ratings and reviews for wellness solutions and providers. Every month, WE publish Index Reports that reach over 350 major media outlets, including Business Insider, amplifying the most effective solutions and thought-leaders in human optimization.

​

At the heart of everything I do—whether through Small Hinges, Wellness Eternal, or the Optimize W(e) Podcast—is the belief that you don’t have to change everything to change everything. Small hinges swing big doors. With the right data and connections, even the smallest action can unlock massive breakthroughs in health, longevity, and human potential.
