India’s Ultrahuman Raises $70M to Supercharge On‑Device AI in Its Smart Ring

Indian wearable startup Ultrahuman has raised $70 million in a new funding round, with backers including Qualcomm Ventures and US diagnostics company Labcorp. The company plans to use the capital to upgrade the on‑device AI capabilities of its health‑tracking smart ring, which monitors biomarkers such as glucose levels, sleep quality and heart rate.

Unlike mainstream generative AI products, Ultrahuman focuses on AI algorithms for biometric analysis, running most of the processing locally on the device instead of in the cloud. This edge‑computing approach is meant to improve privacy and reduce latency, while still delivering personalized coaching and risk insights to users. The fresh funding will support work on custom low‑power chips, more efficient AI models, and an expansion push beyond the Indian market.

Smart rings and other discreet wearables are becoming a hot segment in the US and Europe as well, and the industry is grappling with a key architectural choice: which tasks to hand off to cloud‑based AI and which to keep on‑device. Ultrahuman’s strategy is emerging as a prominent test case for how to balance rich health data analytics with stricter expectations around data protection and user control.
