Circular Health

Circular is building the next-generation platform for continuous, remote health monitoring. Our flagship product, the Circular Ring 2, is the world's only consumer smart ring with a built-in ECG and FDA-cleared AFib detection, tracking 140+ biomarkers around the clock. Powered by Kira, our AI health assistant, the ring delivers personalized health insights with no mandatory subscription, a clear differentiator in a subscription-heavy market. Blood pressure monitoring is rolling out in 2026, with glucose trend tracking on the near-term roadmap to deepen our clinical validation, and scale our B2B2C partnerships.
