Temple Secures $54 Million to Pioneer Head-Worn Brain Health Wearables

A New Frontier in Health Monitoring

Temple Pvt. Ltd. has successfully raised $54 million in its first funding round, valuing the startup at approximately $190 million. Founded by Zomato CEO Deepinder Goyal, the company aims to move health monitoring from the wrist to the head. This unique friends and family round saw heavy participation from early stage investors and over 30 Temple employees who invested their own capital at par valuation.

Introducing Brain Flow Technology

The flagship product is a non-invasive wearable worn on the temple using gentle medical-grade adhesives. It introduces a metric called Brain Flow, designed to track cerebral blood flow as a proxy for aging and neurological health. This technology distinguishes itself from competitors by focusing on the temple area, where skin is thinner and capillaries are more accessible for high-fidelity optical readings.

The Gravity Ageing Hypothesis

The device is built around the Gravity Ageing Hypothesis, which suggests that gravity pulls blood away from the brain over time, potentially accelerating the aging process. While standard trackers monitor heart rate and sleep, Temple prioritizes blood flow to the brain as a critical biomarker. The company cites research linking lower cerebral blood flow to higher mortality rates in older adults at https://pubmed.ncbi.nlm.nih.gov/24174588/.

Built for Performance

Temple is currently assembling a specialist team to refine the device for elite performance athletes and longevity enthusiasts. Beyond brain metrics, the device tracks heart rate, HRV, sleep patterns, and VO2 Max to provide a holistic health picture. The startup is positioning itself as a premium tool for those seeking a complete understanding of their physiological health from head to toe.

Looking Ahead

Although the product remains in an experimental phase, the company has already opened a waitlist for early adopters. Future developments will focus on proving that Brain Flow is not just a readable metric but an actionable one for improving long-term health. With a dream team being built, the industry is watching closely to see if this head-worn sensor can redefine the wearable market.
