Company strategy: urgency and long-term focus

From a child prodigy in a genetics lab to building a company that can pause life itself, Laura Deming has made a career out of chasing time. At just eight years old she became obsessed with aging. At eleven, she joined Cynthia Kenyon’s pioneering longevity lab. At seventeen, she launched The Longevity Fund—one of the first venture firms dedicated to extending human healthspan. Now, she’s tackling her boldest challenge yet: building a “pause button” for biology.

As the co-founder of Until, Laura is developing reversible cryopreservation: the ability to cool living tissue to ultra-low temperatures, hold it there, and then bring it back fully functional. By achieving vitrification (the process of turning tissue into glass instead of ice), Until aims to make organ preservation, and eventually medical hibernation, a reality.

We cover:

• Why longevity was once stigmatized, and what changed to make it one of the most credible fields in biotech today

• Why Until’s approach focuses on preserving the living, not the dead

• The physics and biological challenges of scaling reversible cryopreservation from embryos to human-sized organs

• How vitrification is making cryopreservation possible

• How this breakthrough could transform organ transplantation by eliminating time constraints (and eventually enable medical hibernation)

• The philosophical and social implications of being able to “pause” life and effectively time travel into the future

• How growing up homeschooled in New Zealand shaped Laura’s unconventional way of thinking

• The story of how legendary biologist Cynthia Kenyon invited 11-year-old Laura into her lab, sparking her lifelong obsession with aging

• How she learned to embrace her weirdness and trust it as her creative superpower
