World’s Top HealthTech Companies of 2025

Developing accurate and inexpensive ways to diagnose disease also remains a challenge, although a few standout companies such as Fedo, which uses a selfie to assess certain vital signs, and Canary Speech, which uses a person’s voice to detect various cognitive and behavioral disorders, (both marked Outstanding performance in Diagnostics) are making strides using new AI tools. “Voice is the most complex motor function we produce in the body. It’s very, very rich in information,” Canary’s co-founder and CEO Henry O’Connell said at a conference in 2025. “If there is a defect of some kind, whether it’s a cold or whether it’s a progressive neurological disease, all of them impact on the central nervous system’s ability to control and create language.”

Digital health’s primary benefit will be in empowering patients to both learn more about their health, and also to take action to either avoid or manage conditions better. Companies like Oura (marked Outstanding performance in Medical Devices & Wearables) that produce wearable health devices and telehealth entities continue to find new ways to keep people informed and connect to health care providers, as patients demand the same transparency and depth of information that they enjoy in other parts of their lives—retail and transportation to name a couple—in the way they manage their health.
