Former Zomato CEO backs temple-worn wearable to track brain blood flow, signaling a shift from food tech to human performance.

When Indian billionaire entrepreneur Deepinder Goyal, best known as the CEO of the food delivery giant Zomato, stepped down in January from the company he co-founded nearly two decades ago, many expected a pause. Instead, he has returned with a different kind of ambition.

Temple, his new wearable startup, has secured $54 million in a friends-and-family round at a post-money valuation of about $190 million. The raise was led by Goyal himself, followed by Steadview Capital, according to regulatory filings first reported by TechCrunch [1].

Other investors include Peak XV Partners, Info Edge Ventures and Dharana Capital, alongside high-profile angels such as Vijay Shekhar Sharma of Paytm, Kunal Shah of CRED and Zerodha founders Nithin and Nikhil Kamath.

More than 30 Temple employees invested at the same valuation, Goyal shared on X. That detail matters. When early team members write checks alongside seasoned investors, it suggests belief not just in a cap table, but in a mission.

Goyal described his shift as a move toward “higher-risk exploration and experimentation.” After building Zomato into one of India’s largest consumer internet platforms, he is now placing a bet on something far less proven: measuring the brain in motion.

Why the brain, and why now? Temple is developing a wearable designed to sit on the side of the head, near the wearer’s temple. Its aim is to continuously track cerebral blood flow – essentially, how much blood is reaching different parts of the brain over time. That may sound clinical, but the underlying idea is surprisingly intuitive.

If the heart is the engine of the body, the brain is the command center. And just like any high-performance engine, it depends on fuel. In this case, that fuel is oxygen-rich blood. When blood flow shifts, cognitive performance can shift with it – affecting focus, reaction time and decision-making under pressure.In a January podcast conversation, Goyal described Temple’s ambition as building “the ultimate wearable for elite performance athletes,” capable of measuring metrics that current devices cannot. Unlike wrist-worn trackers or smart rings, which primarily monitor heart rate, sleep cycles and activity, Temple is aiming higher up the body [2].

Most wearables today use the heart as a proxy for performance. Temple wants to look at the brain directly. It is a bold claim in a market where companies like Oura, Whoop and Garmin have spent years refining hardware and building trust with athletes. Those devices already offer increasingly sophisticated data on recovery and strain.

Temple’s wager is that the next frontier is not just how hard your heart is working, but what your brain is doing while it happens.

Tracking cerebral blood flow has traditionally required bulky machines in controlled environments. Temple’s challenge is to shrink that into something wearable, comfortable and reliable.

The company is hiring across embedded systems, computational neuroscience and brain-computer interface engineering. That means three things: building the physical device, making sense of the brain signals it captures and translating that data into feedback an athlete or coach can actually act on.

If heart-rate data tells you how hard your body is pushing, brain blood flow data could, in theory, reveal how well your mind is coping with that stress. But the “in theory” is important.

Skin-mounted sensors measuring deep-brain signals are technically complex. Accuracy, noise and interpretation will determine whether Temple becomes a breakthrough or a bold experiment. The science must not only work; it must work consistently outside a lab, in sweat, movement and real-world intensity.

Investors appear willing to fund that uncertainty. Perhaps that is part of a broader shift in venture capital, a renewed appetite for deep tech after years dominated by consumer apps and incremental software.

At first glance, a device for elite athletes may feel distant from everyday longevity. But high performance and healthy aging are increasingly intertwined.

Longevity is now framed about extending healthspan. Blood flow to the brain is central to that story. Subtle declines over time have been associated with cognitive impairment and other age-related challenges. Temple’s current focus is peak performance. Yet the same tools that help an athlete understand mental fatigue could eventually inform how we monitor cognitive resilience as we age.

The arc is familiar. Heart-rate monitors were once niche tools for elite competitors. Today, they are standard features on mass-market wearables. If Temple succeeds, brain-centric metrics could follow a similar path. First for professionals, then for the rest of us.

Goyal’s broader investment moves reinforce that possibility. In October 2025, he committed $25 million of his own capital to Continue Research, a venture exploring human lifespan extension. The throughline pivots from optimizing food delivery logistics to optimizing human biology.

Temple has not announced a launch date. It has not published clinical data. What it has secured is time and capital – $54 million to test whether its thesis holds. There is risk here. The wearables market is competitive. Scientific validation takes patience. Translating complex brain data into simple, actionable insights is harder than it sounds.

But there is also vision. For a founder who spent years refining restaurant logistics and last-mile delivery, turning to cerebral blood flow might seem like a dramatic leap. In reality, both pursuits share a common thread: optimization. One sought to deliver meals more efficiently. The other aims to understand how the body’s most complex organ performs under strain. If longevity is about preserving our mental edge as much as our physical health, then Temple’s bet lands squarely in that conversation.

The brain has always been the quiet driver of performance and aging alike. Temple is betting that, soon, we will be able to measure it as easily as we measure our pulse – and that doing so could change how we train, recover and, ultimately, how we age.
