Until (Until Labs) is a biotechnology company building the medical infrastructure to pause biological time. It is developing reversible cryopreservation systems for human organs, starting with organ-scale reversible cryopreservation to solve the donor-organ procurement and matching problem, and methodically scaling toward whole-body preservation. The lab translates the fundamentals of cryobiology into engineered workflows across five dimensions — perfusion, cryoprotectants, cooling, rewarming, and organ health assessment — using vitrification (glass, not ice) to prevent ice formation during preservation and safe rewarming. Founded by Laura Deming and Hunter Davis, Until has raised $100M+ to date and is backed by Founders Fund. Until is a research-and-development company with no public API surface; this profile captures its identity and public web properties for the API Evangelist network.
