Deepinder Goyal Opens Early Access for Temple, a Brain-Health Wearable Focused on Blood Flow

The selective trial points to a push into wearables for brain health, with emphasis on blood flow plus cognitive performance.

Overview

  • Temple, which Goyal announced Tuesday on X, has its first 100 units ready to ship to a curated group of founding users.
  • Applications are open for athletes, scientists, doctors, founders, creators, and people who prioritize physical and cognitive health, with selection aimed at those who can give structured feedback.
  • The clip-on device sits at the temple to read signals such as cerebral blood flow and skin activity, using the area’s thinner tissue and dense blood vessels to improve signal quality.
  • The rollout stays experimental as pricing, full specifications, and a broader release timeline have not been disclosed.
  • The project links to Goyal’s Gravity Ageing Hypothesis, and he hinted that some early users could get a chance to join a future funding round.
