What is Zomato's CEO wearing on this forehead?

Deepinder Goyal, co-founder and CEO of Zomato, showed up on Raj Shamani’s podcast wearing a tiny, weird thing on his forehead and said nothing about it.

This 4+ hours episode was dropped on January 3, 2026, where Deepinder unpacked stories about Zomato, Blinkit, entrepreneurship, and scale, but people couldn’t stop staring at that thing near his temple.

So they started asking questions, searching for it on Google. 

Only to find out that the device near his temple is called “Temple”, his new startup. 

It is an experimental brain-monitoring wearable that continuously tracks cerebral blood flow as part of his research into what he calls the Gravity Ageing Hypothesis.

But the most impressive thing here is his smart marketing move, he didn’t say a word about his startup, he didn’t introduce the device, the only thing he did was spark curiosity in millions of people, and the rest of it aligned itself. 

Is this the future? Marketing that doesn’t look like marketing? Products that sell themselves? What do you think?
