Shubman Gill tests Zomato founder’s unreleased AI fitness device Temple

What Temple does

The device, called Temple, is an AI-powered fitness tracker designed to be worn on the forehead. According to reports, it measures physiological metrics such as cerebral blood flow, nervous system activity, and cognitive stress while the user is active.

Unlike traditional wrist-based wearables, Temple’s positioning above the eyes targets data points that could offer insights into how the body—particularly the brain—responds to physical strain during training or competition.

Who has used it so far

Temple has yet to be commercialized, but it has been spotted in use by professional athletes. India batter and ODI and Test captain Shubman Gill was seen wearing the device during a practice session in Auckland. He used it while batting in the nets alongside cricketers Ishan Kishan and KL Rahul.

Indian badminton player PV Sindhu has also been photographed wearing Temple in the past, suggesting the device is undergoing testing in multiple high-performance sports environments.

What’s next for the device

No official launch date, pricing, or detailed technical specifications have been shared. According to the company, the device aims to help athletes and users understand their body’s response to intense physical stress, though its broader applicability remains unproven.

Temple’s development is led by Deepinder Goyal, founder of Zomato, through his venture beyond food-tech. The project reflects a growing trend of founders exploring hardware-driven health tech, though its success will depend on regulatory compliance and market adoption beyond elite sports.

What this means

Lazyfounder analysis — our interpretation, not reported fact.

Deepinder Goyal’s pivot from food-tech to wearable health technology signals growing founder interest in merging elite sports performance with consumer hardware. For founders and operators, Temple’s pre-commercial testing by professional athletes underscores how early adopters in high-stakes environments can serve as both product validators and marketing assets—without the costs of traditional endorsement deals. The forehead-worn form factor and focus on cognitive stress also suggest a niche that could differentiate Temple from wrist-based wearables, though its eventual commercial appeal will hinge on whether it scales beyond elite athletes.

Key takeaways

• Founders in wearable tech should note how Temple is leveraging professional athletes for real-world validation, a strategy that could reduce customer acquisition costs.
• The device’s emphasis on cerebral and nervous system metrics may appeal to fitness markets beyond cricket or badminton, particularly in stress-heavy professions.
• Zomato’s shift into hardware highlights how founder-led startups can explore adjacencies, but operators should weigh the risks of entering regulated sectors like health tech.
