Founder praises Deepinder Goyal’s Temple device, calls it ‘wild and fascinating’

Goyal was recently seen wearing the device during a podcast appearance, reigniting conversation around his “brain blood flow experiment. Sharing a picture of the Zomato chief wearing the device on his left temple, Swapnil Srivastav, founder of Kidbea, wrote on X that the device, called Temple, tracks blood flow to the brain.

“Deepinder wearing a device called Temple to track blood flow to the brain and it’s wild and fascinating,” Srivastav said. He further explained Goyal’s belief, saying that it is simple and radical”. “People don’t die because of disease. They die because of gravity,” he wrote, explaining that over time gravity slows blood flow to the brain, which then triggers ageing and eventually death. He added that Goyal is “working on something to never let that blood flow stop” and suggested this could change longevity if it works.

“Maybe that’s why the parent company is called Eternal,” Srivastav noted.

In November 2025, Goyal shared what he called the “Gravity Aging Hypothesis”. At the time, he suggested that gravity may gradually reduce blood supply to the brain over a lifetime and that this reduced blood flow could be linked to ageing.
