Sleep Tech Startups funded by Y Combinator (YC) 2026

Equipt Health makes it easy for any healthcare company to offer prescription medical devices to patients. We handle the whole process: the packaging, the logistics, the clinical (via our provider network) and technical support, and the return of data from connected devices. We're starting with the diagnosis and treatment of sleep apnea at heliosleep.com.

Zeit Medical leverages the power of AI and wearable sensors to deliver peace of mind for those affected by stroke. Zeit’s smart headband immediately detects the onset of stroke and notifies 911. Each year more than 90% of the one million strokes in the US go untreated, resulting in life-long disability and exploding medical costs north of $100b. The lack of timely treatment is the result of delays in alerting the emergency services. More than 10 million Americans with an elevated stroke risk live with constant fear that a stroke may go unnoticed for hours, while they are asleep or alone. The company was founded by Orestis Vardoulis PhD a biomedical & mechanical engineer and expert in digital health (EPFL/Stanford) and Urs Naber MD a critical care physician (Dartmouth/Stanford). They have both seen the devastating effects of stroke in their families and came up with the idea of addressing this unmet clinical need during their Stanford Biodesign Innovation Fellowship.

Evolve builds consumer apps used by millions. We're a YC W18 company with two products. Rest (getrest.app) is an AI sleep coach for people tired of bad nights, whether that's lying awake for hours or waking up at 3am. It's built on the principles of CBT-I (cognitive behavioral therapy for insomnia), the method sleep clinicians recommend first, and turns them into a daily program with a coach you can talk to at any hour. No appointments, no waitlists. People use it to sleep well again without leaning on melatonin, sleep aids, or 2am doom-scrolling. Users often go from years of broken sleep to sleeping through the night in weeks. We build Rest with sleep scientists and behavior-design experts. Podcast App is one of the largest independent podcast players: a minimalist app with tens of millions of downloads that uses machine learning to build playlists around what you like. Our team has built consumer products with 100M+ installs, and our work has been featured by Apple, TechCrunch, Yahoo, Fast Company, and Fox. Get in touch: hello@getrest.app.
