About Until

Until is a moonshot company building a “pause button” for biology. Our near-term focus is organ-scale reversible cryopreservation: preserving donated organs at subzero temperatures without ice formation, then rewarming them uniformly for transplant. By solving this challenge, we are laying the foundation for whole-body reversible cryopreservation, giving patients a bridge to future cures.

To achieve our goal, we are assembling an interdisciplinary team to develop perfusion systems, cryoprotectant formulations, and vitrification and rewarming hardware.

We envision a future where no transplantable organ is lost to logistics, and no terminal diagnosis is final because patients can safely wait for future medicine to arrive.

About the Company

UntilLabs

Advances reversible organ cryopreservation technology

UntilLabs develops reversible cryopreservation technology to extend the viability of human organs for transplantation. The goal is to keep organs alive at cryogenic temperatures long enough to improve organ matching and reduce waste from time limits, potentially weeks or months of preserved time. The approach uses cooling to very low temperatures (below -130°C) with cryoprotectants to prevent ice damage, followed by advanced warming methods to revive the organs without harm. While cryopreservation has worked for cells and simple tissues, UntilLabs works on scaling this to whole organs, tackling challenges like ice formation and nutrient/waste management in large tissues. In the long term, the company envisions whole-body reversible cryopreservation as a bridge to future medical cures.
