When his wife’s employer started offering a program from startup Twin Health, he thought he would give it a try. Mountain View, California–based Twin Health’s approach uses a combination of wearables, AI, and on-demand health coaching to help manage diabetes, prediabetes, and obesity. Together, the devices collect data points on blood sugar, weight, stress, blood pressure, sleep, and activity and feed them into a single app. The program has led to medication savings for asset manager Blackstone, which has been using Twin Health for several years, while helping employees there lose weight. “We are making an impact on people, and we are sustaining the health outcomes,” says Jahangir Mohammed, cofounder and CEO of Twin Health.
