Deepinder Goyal, founder of Eternal, is exploring the launch of Temple, a wearable device company focusing on brain health through real-time cerebral blood flow monitoring. The device, linked to his Gravity Ageing hypothesis, marks a novel step in wearable tech aimed at longevity and cognitive wellness.

Deepinder Goyal, the founder of Eternal and a notable entrepreneur in the health and tech sectors, is taking a pioneering step forward by exploring the launch of a new wearable technology company named Temple. The venture seeks to develop and commercialize wearable devices that monitor cerebral blood flow to the brain in real time, signaling a fresh focus on brain health and ageing.

Key Highlights:

- Temple’s website currently displays a simple “Coming Soon” message accompanied by a teaser line: “The future of health starts where no one’s looking. Inside your brain,” hinting at the innovative neurotech focus of the company.

- The wearable device is an experimental sensor that Goyal has personally used for about a year as part of his research under Continue Research, a biological initiative he funds and leads.

- The device aims to track brain blood flow continuously, which is already accepted as a biomarker for ageing, longevity, and cognitive functions.

- This technology ties closely with Goyal’s Gravity Ageing hypothesis, which proposes that gravity's long-term impact on blood flow to the brain contributes to human ageing.

- Goyal emphasizes that even if the Gravity Ageing hypothesis does not hold, the wearable remains useful and relevant for brain health monitoring.

- Temple is described by Goyal as a “small, cute company” in contrast to the scale of his other ventures like Eternal or Zomato, indicating a focused and niche approach at the outset.

- The debut of Temple follows a $25 million seed investment from Goyal into Continue Research to advance longevity science.

- The wearable has drawn attention after social media circulated images of Goyal wearing a prototype device near his temple, sparking widespread speculation.

- Experts advise that the device and hypothesis require rigorous scientific validation and peer review before clinical or commercial claims can be made.

- If successful, Temple’s innovation could open pathways for practical wellness interventions targeting brain ageing and cognitive health.

This move by Goyal highlights a growing interest in deep tech wearables focused on health monitoring beyond the conventional metrics, aiming to bridge scientific research with consumer-ready health technologies.
