Eternal, a health and longevity startup targeting avid athletes, has launched a new product: weekly AI-generated personal podcasts that update users on their latest health metrics. The move aims to make sense of the glut of health data consumers collect from wearables and lab tests.
Founded in early 2025, Eternal raised a $13.25 million seed round led by Lightspeed Venture Partners. Users connect wearables or upload lab data; the platform compiles and analyzes the information over time, tracking changes toward goals like weight loss or improved sleep. The new “audio experience” delivers a short weekly summary of those updates.
Eternal competes in the crowded digital health space, where players like InsideTracker and Levels offer similar data-driven personalization. However, the firm differentiates by focusing exclusively on high-end athletes and translating quantitative metrics into an engaging, narrative format — not just dashboards or PDFs.
This product signals a shift toward multimodal health interfaces: as wearables proliferate, startups are betting that audio is the next channel for coach-like feedback. If successful, Eternal could expand beyond athletes into broader wellness audiences seeking simpler data digestion.
President Alex Mather previously founded The Athletic, the sports news publication sold to The New York Times in 2022. Mather brings media-and-audio expertise to a space traditionally dominated by physicians and data scientists — a background that may prove crucial to making health data truly usable.
