A biotech startup has been exploring brainless human clones for years. This could reshape longevity markets and healthcare investing.

The Big Picture

Cloning Bet: The Stealth Race for Brainless Bodies

R3 Bio operated in stealth until last week. The Richmond, California startup announced it raised money to create nonsentient monkey "organ sacks" as an alternative to animal testing. But internal documents reveal a broader vision: brainless human clones to serve as backup bodies.

Founder John Schloendorn has pitched this idea in private circles. He's shown medical scans of children with birth defects missing most cortical hemispheres as evidence a body can live without much brain.

"The team reserves the right to hold hypothetical futuristic discussions," cofounder Alice Gilman said when pressed about brainless clones.

Longevity biotech attracts aggressive venture capital. Three investors back R3 Bio: billionaire Tim Draper, Singapore-based fund Immortal Dragons, and life-extension investors LongGame Ventures. These players seek transformative returns, not incremental ones.

Schloendorn and Gilman presented at Abundance Longevity, a $70,000-per-ticket event in Boston. The "Full Body Replacement" session discussed personal clones for spare organs according to an attendee. This suggests high-net-worth investors are funding frontier concepts.
