Kate Tolo, an Australian-Bosnian marketing strategist and the girlfriend of tech venture capitalist Bryan Johnson, will spend $2 million per year to participate in a rigorous health experiment.
Rising to prominence after founding the digital payments company Braintree, which acquired Venmo before being sold to PayPal for $800 million in 2013, Johnson shifted his focus to neurotechnology and longevity, and became a self-proclaimed “biohacker.”
In 2021, Tolo joined Johnson’s brain-interface company, Kernel, and later co-founded and led the branding of his personal anti-aging brands, Blueprint, Don’t Die, and Immortals.
