SUMMARY:
- Temple wearable by Deepinder Goyal monitors cerebral blood flow continuously through a head-worn sensor
- Raising $50 million seed round at $125-130 million valuation from Steadview Capital and Peak XV Partners
- Connected to Gravity Ageing Hypothesis suggesting gravity reduces brain blood flow by 17% in upright posture
Temple wearable is Deepinder Goyal‘s experimental brain health device that continuously monitors cerebral blood flow through a small sensor worn near the temple region. The Eternal founder unveiled this groundbreaking healthtech venture in November 2025, sparking massive attention across India’s startup ecosystem.
Temple is raising $50 million from marquee investors including Steadview Capital, Vy Capital, Info Edge, and Peak XV Partners, marking one of India’s largest seed rounds for a wearable startup. But what makes this tiny golden patch so revolutionary?
What Is Temple Wearable by Deepinder Goyal?
Temple wearable is a head-worn sensor positioned near the temple region that continuously monitors brain blood flow in real time. Unlike traditional fitness trackers that focus on steps and heart rate, Temple targets cerebral blood flow (CBF) as a key biomarker for aging and cognitive health.
Goyal described Temple as capable of accurate, continuous, and real-time measurements of brain blood flow during daily activities, unlike conventional devices that rely on short clinical tests. The device appears as a small golden patch attached near the eyebrow area.
Goyal revealed he has been using the device for about a year, developing it initially for research purposes under Continue Research, his $25 million biological research initiative focused on longevity science.

The Science Behind Temple: Gravity Ageing Hypothesis
Temple’s development connects directly to Goyal’s controversial Gravity Ageing Hypothesis unveiled in November 2025. The hypothesis suggests that when humans stand or sit, gravity pulls blood away from the brain, reducing cerebral blood flow by up to 17% in upright posture.
Continue Research claims that daily passive inversions for at least 10 minutes using commercial inversion tables over six weeks lead to a 7% increase in daily average brain flow, equivalent to approximately 10 years of younger age.
The theory sparked intense debate online. Goyal positioned the hypothesis as an open-source contribution to longevity science rather than a corporate pitch. Medical experts like Dr Cyriac Abby Philips called the theory unsupported, while others found it intriguing enough to warrant further investigation.
Goyal emphasized the hypothesis is not a claim of truth but a well-researched, testable idea that merits deeper scientific scrutiny. He clarified that Continue Research established a dedicated team to attempt invalidating the hypothesis, demonstrating commitment to rigorous scientific method.

Temple Wearable Funding and Valuation
Temple is in advanced talks to raise $50 million at a valuation between $125-130 million, making it one of the largest seed-round valuations for an Indian startup.
The funding round involves Steadview Capital, Vy Capital, Info Edge, and Peak XV Partners, with Goyal and other Indian founders investing personally. Temple employees are also expected to participate in the round.
These are the same institutional investors who backed Zomato during its early days. Info Edge’s Sanjeev Bikhchandani invested ₹5 crore in Zomato in 2010 when it was staring at shutdown, while Peak XV Partners led Zomato’s $35 million Series A in 2013.
The metrics from Temple’s devices are still being benchmarked and validated by third parties, with the device meant to be a research-grade product launching for general audiences after a few months.
Netizens React to Temple Wearable
The announcement generated polarized reactions across social media platforms.
One LinkedIn user commented on the device’s potential, noting that Goyal’s track record with Zomato gives Temple credibility in a crowded healthtech market.
Twitter users expressed skepticism about the timing. “With Zomato’s ongoing Blinkit integration, is launching a hardware venture the right move?” questioned one commenter.
A healthtech founder wrote, “Temple will push existing wearable players to innovate faster. Competition ultimately benefits Indian consumers with better products at competitive prices.“
Critics on X questioned whether peer-reviewed papers exist on the hypothesis, with one user calling gravity ageing theory pseudoscientific. Others praised Goyal for tackling an unexplored area in preventive health.

Temple Website and Launch Timeline
Temple’s placeholder website carries a “Coming Soon” message stating “The future of health starts where no one’s looking. Inside your brain” but lists no specific launch date.
In December 2025, Goyal posted a teaser on social media showing a clear image of the golden device positioned close to the eye. Public interest exploded after photos surfaced from a November Children’s Day event showing Goyal wearing the white experimental patch.
Goyal emphasized Temple would be a “small, cute company, if at all” and “nothing” compared to Eternal, clarifying the Gravity Ageing Hypothesis wasn’t created as a marketing gimmick to sell devices.
Industry sources suggest Temple will initially target research institutions and health-conscious consumers rather than mass market positioning, differentiating it from affordable wearables like boAt or Noise that dominate India’s market.
What’s your take on Temple wearable? Will Deepinder Goyal’s brain health device disrupt India’s wearable market like Zomato transformed food delivery?
