Deepinder Goyal breaks silence amid criticism over Temple device from doctors, influencers : ‘We’re months away from…’
Deepinder Goyal, founder and CEO of Zomato’s parent company, clarified on Friday, January 9, that despite criticism from doctors and influencers, no public announcement has yet been made about the health tracking device Temple. He noted that official device benchmarking data has not yet been released and there is time for preview devices to be released.
In a post titled “A gentle reminder to all concerned doctors and/or influencers” on social media platform
Goyal’s post comes in the wake of criticism from some doctors over the wearable device, which Raj Shamani was recently seen wearing on his YouTube podcast. Some medical professionals and experts have questioned the legitimacy and accuracy of the device.
Describing the situation as amusing, he criticized doctors and influencers who advised against purchasing an unverified device that is not currently available for order.
“You’re advising people not to buy an ‘unverified’ device that isn’t even available for order or pre-order yet. This is ridiculous,” Goyal wrote.
He also assured: “We will share all the science if we decide to sell Temple. You can judge at that time and give all your advice. Until then, be curious and cheer on Indian startups. Your skepticism is valuable, but at the right time.”
What is a temple?
After Deepinder Goyal appeared on Raj Shamani’s YouTube podcast, everyone noticed a small device on his temple and many social media users speculated what it could be. The eternal CEO was wearing a device called the ‘Temple’, an experimental device that continuously monitors blood flow in the brain in real time.
The small gold or silver sensor is worn near the temple. It monitors blood flow to the brain, an important indicator of neurological health and aging. The device is based on Deepinder Goyal’s personal research on the ‘Gravity Aging Hypothesis’. invested 25 million dollars ( ₹225 crore) from his personal funds to develop the startup, according to Mint’s report dated October 24, 2025.
Criticism of the Temple
Dr Cyriac Abbey Philips, popularly known online as The Liver Doc, criticized Goyal in a lengthy post on X for promoting what she described as an “old, already debunked theory of aging” to market a wellness product. He said the product had no scientific basis, likening it to “a greasy band-aid stuck to the temple” and warned against misinformation being branded as a wellness innovation.
Recently, Dr Rahul Chawla, a neurologist trained at AIIMS in New Delhi, consultant at IBS Hospital in Lajpat Nagar and founder of HealthPil.com, called Temple a ‘ridiculous experiment’ driven by ‘obsession with longevity’. ‘
Criticizing the device, Dr Chawla said in an Instagram post: “These billionaires are willing to try anything except believing in qualified healthcare professionals and researchers who have been studying the human body for decades.”
He added: “From what is publicly known, this device appears to be picking up signals from the temporal region, possibly related to surface blood flow or pulse changes. But measuring actual blood flow within the brain is much more complicated. In medical science, even advanced tools such as MRI and specialized research equipment have their limits.”
