AI Advances Highlighted in Time's 2025 HealthTech Leaders

Time’s Health section highlights the world’s top HealthTech companies of 2025, underscoring how artificial intelligence is advancing diagnostics while critics warn that accuracy and cost remain hurdles for widespread adoption. The list spotlights firms making measurable strides in turning data, signals, and everyday interactions into clinical insight, with several earning Outstanding performance ratings in Diagnostics.

Among the standout performers, Fedo uses a selfie to assess certain vital signs, offering a noninvasive way to monitor health status remotely. Canary Speech uses a person’s voice to detect cognitive and behavioral disorders, reflecting a broader effort to translate speech patterns into biomarkers. Canary’s co-founder and CEO Henry O’Connell described voice as the most complex motor function we produce in the body and said that defects of any kind—whether from a cold or a progressive neurological disease—affect the central nervous system’s ability to control and create language, 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." The devices and tools highlighted in the Diagnostics category illustrate how AI is enabling the extraction of clinically useful information from everyday signals. Digital health’s central promise, the Time piece notes, is to empower patients to learn more about their health and to take action to either avoid or better manage conditions, providing a level of transparency and detail that mirrors consumer experiences in other sectors such as retail or transportation.

Digital health’s primary benefit will be in empowering patients to learn more about their health, and to take action to either avoid or manage conditions, producing better outcomes and enabling earlier intervention. This shift toward patient-centered data sharing and ongoing monitoring follows a broader push across industries to deliver deeper, more transparent information.

Oura, marked Outstanding performance in Medical Devices & Wearables, represents the wearable and remote-monitoring frontier in HealthTech. The company’s devices collect sleep, activity, and physiological signals and connect users with telehealth services so they can discuss results with clinicians. The Time list frames wearables and telehealth as essential bridges between patient data and medical care, a trend that resonates with patients seeking continuity of care outside traditional clinic visits.

While the progress showcased on the Time list is notable, industry observers caution that diagnostic accuracy, cross-population validation, data privacy, and cost remain core challenges. Experts say AI-driven diagnostics are most useful as decision-support tools that augment clinician judgment, and that scale will depend on rigorous validation, interoperability with electronic health records, and clear reimbursement pathways. In the near term, the principal payoff of digital health may lie in empowering patients with information and actionable insights, rather than replacing face-to-face care.

Looking ahead, analysts expect the HealthTech landscape to continue tilting toward platforms that combine AI-enabled diagnostics, continuous monitoring, and accessible telemedicine. The trend underscores a broader shift in health care toward patient-centric models that use data and AI to inform decisions, improve prevention, and make care more transparent for consumers.
