• Temple, a wearable brain-monitoring startup founded by Zomato co-founder Deepinder Goyal, raised $54 million in a friends-and-family round at a post-money valuation of about $190 million (TechCrunch, February 2026).1
  • Signals investor interest in consumer neurotech and wearable brain monitoring.1
  • The device is a non-invasive sensor worn on the temple that continuously tracks cerebral blood flow via near-infrared spectroscopy (NIRS); Temple claims the temple region offers thinner skin and higher blood flow than the wrist, enabling cleaner physiological signals.2
  • Temple is built around Goyal’s “Gravity Ageing Hypothesis”: the theory that gravity chronically reduces cerebral blood flow over a lifetime (estimated at ~0.7% per year, or a 20–40% decline from ages 20 to 80), contributing to accelerated cognitive decline.3
  • Investors include Steadview Capital, Peak XV Partners, InfoEdge Ventures, Vy Capital, and Dharana Capital, alongside angel investors Vijay Shekhar Sharma (Paytm), Kunal Shah (CRED), and Nithin and Nikhil Kamath (Zerodha); more than 30 Temple employees also invested at par valuation.1
  • Goyal personally committed the largest single investment, reportedly over ₹104 crore (~$12M), alongside a separate $25M investment in his longevity research initiative, Continue Research.3
  • Beyond cerebral blood flow, the device tracks heart rate, HRV, sleep patterns, and VO2 max, positioning it as a holistic performance tool competing with Whoop and Oura.4
  • By May 2026, Temple shipped its first 100 units in early access and partnered with Zetwerk and Ethereal Machines for precision sensor manufacturing and production scale-up targeting thousands of units for both Indian and US markets.2
  • The company is hiring across embedded systems, computational neuroscience, BCI engineering, and neural decoding; Goyal has described it as “the ultimate wearable for elite performance athletes.”1
  • The device remains experimental and not FDA-cleared as a medical device; some physicians have publicly questioned its scientific standing, noting that cerebral blood flow monitoring at clinical precision in a consumer wearable has not been independently validated.4
