Bryan Johnson (born 22 August 1977) is an American entrepreneur, venture capitalist, and longevity researcher whose work explores the technological transformation of human biology. Born in Provo, Utah, and raised in nearby Springville, he served a Latter-day Saint mission in Ecuador before earning a degree from Brigham Young University and an MBA from the University of Chicago.
In 2007, Johnson founded Braintree, a mobile and web payment platform that powered services like Uber and Airbnb. In 2012, Braintree acquired Venmo for $26.2 million, and in 2013, PayPal acquired Braintree for $800 million, earning Johnson over $300 million. He subsequently invested $100 million of his personal capital in the OS Fund, supporting transformative science startups in synthetic biology, artificial intelligence, and space exploration.
In 2016, Johnson founded Kernel, investing another $100 million to develop non-invasive neural interface technologies for measuring brain activity. In 2021, he launched Project Blueprint—a comprehensive anti-aging protocol involving strict nutrition, supplements, fitness regimens, and medical monitoring by a team of 30 specialists. His self-funded longevity initiative involves over 100 daily protocols, with Johnson claiming to age at a rate 46% slower than average.
Johnson’s work represents a contemporary expression of transhumanist ambitions—the application of technology and rigorous methodology to extend healthy human lifespan. While his methods have attracted skepticism from some medical experts, his willingness to invest in and personally test radical approaches to human enhancement has made him one of the most visible figures in the longevity movement.
