Zomato founder Deepinder Goyal has always made headlines for his entrepreneurial journey. But this time, recent appearance on Raj Shamani’s ‘The Figuring Out’ podcast, it was not Goyal's opinions on business and startup quotes and lessons for budding entrepreneurs alone that made headlines. It was the tiny shiny object he was wearing around his eye that made all the onlookers curious.
What is ‘Temple’?
Goyal was wearing a health-tech device called Temple. This is Goyal’s entry into the deep-tech space and the world of medical research. Temple, which he first showed the world in December 2025, provides real-time, continuous monitoring of brain blood flow. This is a space that hasn’t yet been explored by wearables.

Goyal, who is also the head of Eternal, Zomato’s parent company, first posted a sneak peek on Instagram with the caption, "Getting there.” While giving away little in terms of its final look, Goyal has explained on LinkedIn that Temple is, in fact, an “experimental device to calculate Brain Flow accurately.”
A window into the brain
As per a report by Free Press Journal, the device resonates with Goyal's continuous research into the Gravity Ageing Hypothesis, a concept studying the influence of neurological and gravitational factors on biological ageing. Continuous monitoring of brain blood flow stands at the core of cognition studies, longevity, and neurological health. Goyal said, "Been using it for a year, and I've been feeling that this could shape into an important wearable the world needs. Brain Flow is already well accepted as a biomarker for ageing, longevity, and cognition. So, this device is useful and relevant even if the Gravity Ageing Hypothesis turns out to be wrong.”
Temple is being developed as a lightweight, daily-wear device, potentially combining advanced sensors with AI-driven data analysis. It also proposes to give valuable information on mental fatigue, memory, focus, sleep, and stress, where normally the insight of conventional fitness trackers is minimal.

Though there is no information available for the launch and the regulatory strategy, the fact that Goyal has appeared in public with Temple is an indication that the development stage has begun in full swing. By making it an incidental debut on a popular podcast, he might also be hinting that the transition of Temple from the laboratory to the limelight is about to take place.
