These wearables placed on the temple continuously measure cerebral blood flow to optimise training, recovery, work, and sleep. The device leverages physiological signals from areas with dense vascular and neural activity to generate deeper insights into human performance. The company claims this placement enables cleaner and richer data capture compared to conventional wearables.

The devices will be offered selectively to a group of users, including athletes, scientists, founders, doctors, and creators, with a clear emphasis on individuals deeply invested in physical and cognitive health.


The rollout is not a broad consumer launch. Instead, Temple is positioning this phase as a feedback-driven pilot. Per Goyal, applicants will be screened, and only a small cohort will be chosen based on their ability to provide critical feedback and actively shape the product’s evolution.

“After you apply, we will get in touch with the selected few who we think will provide us the most critical feedback, and help us shape Temple’s future. You could also get a chance to invest in the next round of funding for Temple,” Goyal wrote in a post on X.

For early access, the website directs applicants to a form seeking basic details like name, email address, and mobile number, links to their social media handles, and a brief statement explaining why they’re interested in trying the device.

The startup raised $54 million (Rs 493 crore) in seed funding in February, which valued the company at $190 million (about Rs 1,700 crore). ET had reported that the round saw participation from Peak XV Partners, Steadview Capital, Dharana Capital, Info Edge Ventures, along with over 80 angel investors, according to regulatory filings.
