Removing Time from the Equation

X-Therma enables the robust preservation of cells, tissues, organs, and other biologics by leveraging our proprietary peptoid. The peptoid inhibits lethal ice crystals, allowing long-term sub-zero storage of biological materials while maintaining unparalleled functionality and viability. 

X-Therma is headquartered in Richmond, San Francisco Bay Area, and has expanded to Austria in Europe.

About X-Therma

A tragic loss during Xiaoxi’s childhood due to a lack of organs set her on a course to find answers. Nearly two decades later she founded X-Therma and the dream for readily available organs is about to turn into reality.
