We are optimistic that human whole-body reversible cryopreservation is solvable. We've built a world-class multidisciplinary team and raised $48M to tackle this problem.

( Until it’s possible. ) Science & Technology Our Approach The challenge is simple to state, but demanding in practice: pause molecular motion in every cell of an organ, then safely resume it. To do so, we engineer across five dimensions: perfusion, the cryoprotectants themselves, cooling, rewarming, and assaying organ health. Each breakthrough at the organ scale teaches us how to orchestrate these processes at larger, more complex levels. Perfusion We repurpose biology’s own delivery network. Perfusion is the process of flowing fluid through a biological system, using pressure,…
