Eli Health
Eli Health is a health-tech startup offering an “instant hormone monitoring” platform based on saliva testing and a phone app. Their goal is to make hormone tracking as accessible and seamless as checking your heart rate. On their website, they emphasize that hormones shift constantly, but current lab tests only offer infrequent snapshots — they aim to change that by enabling continuous, real-time hormone insights. They’ve built their own technology in-house (including patented processes and manufacturing) and are currently in a beta stage, with cortisol and progesterone tests available and others (like estradiol, testosterone) listed for future rollout. They also say they are developing a longitudinal data set on hormone dynamics and positioning their tool as a shift from reactive to proactive health care.
