About Kate Tolo

Kate is an Los Angeles, CA-based entrepreneur, co-founder and Chief Marketing Officer of Blueprint, Don’t Die, and Immortals. She is also Bryan Johnson's longtime romantic partner and a prominent figure in the public longevity/biohacking space. She was born in Australia, to Bosnian immigrant parents.

She graduated from the University of Canberra with a Bachelor of Fashion in Apparel Engineering and Design, and then worked in fashion in New York as a design assistant at R13, with roles at Proenza Schouler, and Senior Manager of Global Design Operations at The North Face.
Contacted Bryan Johnson in 2016 after reading his work on human-AI co-evolution; after years of outreach she joined his brain-computer interface company Kernel in 2021. She conceived the idea of turning Johnson’s personal health data into a public science experiment, pitched it, and has led the marketing strategy that helped grow his large online following. She then transitioned into co-founding and leading marketing/strategy for Blueprint and related longevity ventures; recognized as a key driver of the project’s public visibility. She is featured in the Netflix documentary Don’t Die: The Man Who Wants to Live Forever. In 2023 she became the first woman to trial the Blueprint anti-aging protocol; more recently she has been running an intensive female-specific protocol, tracking extensive biomarkers across the menstrual cycle and more, aiming to generate detailed women’s health data, with the effort funded at roughly $2–2.6 million per year through Immortals.
