Hiyd develops a 7-gram health-tracking disc that attaches to existing watches with microsuction, collecting biometrics including heart rate, sleep staging, movement, and estimated VO2 max for an iOS or Android app. The startup is training its AI on labeled activity data and plans to add nutrition insights linking eating habits with sleep and workout performance. Founded by former Apple manufacturing design engineer Salah Batroukh, Hiyd plans a November Kickstarter after more than 16,000 people make deposits for its first units.
HIYD introduces its second-generation biometric sensor, designed for seamless health tracking through existing smartwatches. The device eliminates the need for separate subscriptions while integrating directly into wearable technology. It will be showcased during TechCrunch Disrupt 2026 as part of the Startup Battlefield 200 competition.
