At Until, we are building reversible cryopreservation technology. We develop perfusion systems, cryoprotectant formulations, controlled-rate freezers, and vitrification and rewarming protocols for biological systems. Our focus today is organ-scale reversible cryopreservation: preserving donated organs at subzero temperatures without ice formation, then rewarming them uniformly for transplant. By solving this time-critical challenge, we’re laying the foundation for whole-body reversible cryopreservation — pausing molecular motion to give patients a bridge to future cures.
