We are building reversible cryopreservation technology to solve the organ procurement and matching problem.

Cryopreservation is already essential to modern medicine — powering IVF and life-saving stem cell therapies.

Now, we’re extending this technology to whole human organs — transforming hours of viability into weeks, or months, however long is necessary — so that no donated organ is lost to logistics, and no patient dies waiting.

By solving this immediate need, we de-risk and build the foundation for what comes next: whole-body reversible cryopreservation. We're pausing molecular motion to give patients a bridge to future cures.
