Kate Tolo

Kate Tolo is an Australian-Bosnian entrepreneur. She is the co-founder and chief marketing officer of Blueprint, Don't Die, and Immortals, co-founded with Bryan Johnson. She conceived the idea of turning Johnson's personal health data into a public science experiment, pitched the concept, and has overseen the marketing strategy that grew Johnson's following to millions across social media.

Recognized as a viral marketing strategist, she is featured prominently in the Netflix documentary Don't Die: The Man Who Wants to Live Forever, which chronicles the Blueprint project and its global following. She is currently building Immortals, a longevity-focused venture.

Before Blueprint, Tolo worked in fashion — at Proenza Schouler, R13, and The North Face — before joining Johnson's brain-computer interface company Kernel in 2021. She first contacted Johnson in 2016 after reading his work on human-AI co-evolution, and spent years pursuing the opportunity before a position opened.

Born in Mackay, Queensland, Australia, to Bosnian immigrant parents. Her sister, Marianna Tolo, is an Olympic basketball player who won a bronze medal with Australia at the 2024 Paris Olympics. Tolo graduated from the University of Canberra with a Bachelor of Fashion in Apparel Engineering and Design, receiving a Chancellor's Scholarship for Academic Excellence.
