A CPAP built around you.
Reimagining positive airway pressure for obstructive sleep apnea.
A device that adapts.
Rhythm is building a positive airway pressure (PAP) device designed to sense subtle airway collapse and adjust pressure proactively to prevent respiratory events before they happen.
We’ve been there.
Many of us at Rhythm have lived this story. Your sleep test comes back, but you don’t meet the strict diagnostic criteria for OSA. You keep searching, trying whatever you read about online. Nothing makes you feel rested. Then you learn about upper airway resistance syndrome (UARS): frequent respiratory disturbances — an elevated RDI — and finally a name for what you have.
Or maybe, like others here, you are diagnosed. You’re prescribed a CPAP and hope it will finally restore your energy and mental clarity. Night after night, you can’t tolerate it. Your equipment supplier is little help.
PAP therapy is the gold standard, and the least invasive option there is. Yet most people abandon their device within a year,1–3 if they receive one at all. Uncomfortable pressure and poor support push people off a treatment with life-changing potential.
We’ve lived both stories. We’re fixing both failures — the device and the ecosystem around it. And we measure success the way you do: not by numbers from a sleep report, but by how you feel awake.
Let’s talk.
Partner, investor, or simply curious — we’d love to hear from you.
