Temple launch is imminent, Deepinder Goyal reveals team behind its USP Brain Flow technology

Deepinder Goyal has revealed the names of scientists who are behind the development of his upcoming wearable Temple technology. Limited edition of the Temple is confirmed to ship before the end of this year.

In Short

• The wearable sits on the side of the forehead for continuous tracking
• He wants Indians to celebrate scientists as much as they celebrate actors and cricketers
• Temple is expected to help track the blood supply to the brain

Deepinder Goyal wants Indians to cheer for lab coats the way they cheer for cricket jerseys. The Zomato founder has revealed the names of four scientists who are behind Temple’s Brain Flow, a notable technology that sits on the side of the forehead.

In a post on X, Goyal noted that India has always idolised actors and cricketers, and founders of companies are also mobbed at airports. But he wants scientists to add on that list too. "How I wish we started celebrating scientists as much as we celebrate actors, cricketers, and founders," he wrote. He then named the team: Dr. Divya Gulati and Dr. Sanchit Gupta, both from IISc Bengaluru, Dr. Yukti Chopra from SISSA Trieste, and Nitish Kumar from IIT Bombay.

According to Goyal, this team led, built and validated the first continuous, wearable measurement of blood flow to the brain.

Why your brain's blood supply matters

Goyal's pitch is simple. Your brain uses about 20 per cent of your blood supply, and it keeps your hormones, sleep, immunity and repair in check. However, with time or age, that supply starts dropping and most individuals never measure it as well. Even hospitals, he says, can only capture a single snapshot.

His argument is that tracking and maintaining brain blood flow could be one of the most important health and longevity moves of our time. Temple's goal, in his words, is to work on the one problem that sits upstream of every other: extending healthy human life.

What's the proof so far

Goyal recently shared a second validation study on Brain Flow, run against time-domain near-infrared spectroscopy (TD-NIRS). Across 60 sessions with 44 healthy young men, Temple's signal tracked the brain more closely than the scalp. In the head-down tilt test, the correlation was 0.91 for the brain and 0.49 for the scalp. There's a catch, though. The research is a preprint and hasn't been peer reviewed.

When can you buy it

Not just yet. Temple hasn't confirmed a public launch date for India. Goyal has said the limited launch edition will start shipping before the end of 2026, and that a pre-order date could be announced soon once a couple of open items are sorted. The latest version is said to be less than half the size of the earlier one.

Pricing is still a mystery. Earlier reports pointed to around Rs 72,000, while Goyal has hinted at roughly $1,000, or about Rs 1 lakh.
