    We’ve raised $100M+ to date, we are developing reversible cryopreservation for patients in need of donor organs, and we are hiring 🫀🎉🚀

    Did you catch our latest blog post on our rewarming machine? 👀 
With our magnet, a kidney can successfully traverse the danger zone of ice formation in under a minute, using only a few kilowatts. That means it can operate off of standard hospital outlets⚡️ All of our devices

    The central challenge of cryopreservation was never just preservation, it’s also safely coming back. Until Mark 1 shows organ-scale rewarming no longer needs industrial power budgets. A real step toward cryopreservation in transplant centers. Full writeup:

    I'm excited to introduce Mark 1, Until's electromagnet for rapidly rewarming organs from cryogenic storage temperatures. We set out to scale magnetic nanoparticle warming to human-scale organs while keeping the coil losses low enough for hospital use. Mark 1 produces a 900 kHz

    @Dhruv_Sumathi and I made something :) we’ve been filming the beauty of organ preservation research at @untillabs for a while now. it’s not an explainer or company video, it’s a window into how it feels to work on this problem from the inside.
