Bryan Johnson

About

Bryan Johnson is an American entrepreneur, venture capitalist, and longevity pioneer renowned for founding Braintree—a payment processing platform acquired by PayPal for $800 million in 2013 after incorporating Venmo—before launching neurotechnology firm Kernel to develop advanced brain interfaces and OS Fund to invest in frontier science. In 2021, he embarked on Project Blueprint, a data-driven anti-aging regimen involving meticulous monitoring of dozens of organs, a strict vegan diet, over 100 daily supplements, rigorous exercise, and experimental therapies, reportedly reducing his epigenetic age by over five years and achieving the slowest aging speed ever measured in a human, all documented publicly and featured in the 2025 Netflix documentary Don't Die: The Man Who Wants to Live Forever. Shifting focus in 2025, Johnson stepped back from commercializing Blueprint—hiring a new CEO amid plans to potentially sell it—to champion the "Don't Die" movement, a philosophical ideology framing continued existence as humanity's paramount priority in the era of superintelligence, blending biohacking, AI alignment, and species-level survival to inspire global communities toward radical life extension.
