Deepinder Goyal defends Temple wearable amid questions over its science
Zomato co-founder Deepinder Goyal defended Temple, a wearable device marketed for brain and wellness monitoring, after medical experts questioned its scientific credibility.
Critics have challenged whether a sensor worn near the temple can reliably measure blood flow to the brain, and noted that studies on the company’s website were not peer-reviewed.
Goyal said Temple is a fitness and wellness device, not a medical device, and acknowledged it has not been clinically validated.
He said the company has spent $30 million developing Temple, including $20 million of his own money, and pointed to its 14-day return policy.
Goyal said pre-prints and independent studies are expected as the device becomes more widely available.
Pre-orders opened on November 1 at ₹85,000, with shipments expected to start in early 2027.
