This health startup will create a weekly podcast just for you—starring your bloodwork

We’re inundated with data, but for many people, finding a way to make sense of it is elusive. But when it comes to health data, one company thinks it’s found a way to help: with weekly, AI-generated personal podcasts for users, updating users on their latest health and fitness statistics, sleep performance, and more. The podcasts are the latest product offering from Eternal, a health and longevity startup geared toward avid athletes, which combines various services like body scans and bloodwork and turns them into personalized reports and readouts. The company emerged in early 2025 after a $13.25 million seed round led by Lightspeed Venture Partners. It allows its customers to connect wearables or upload their lab data to get started. Health data is compiled and analyzed over time, allowing for the platform to track changes and update users on their progress toward various health goals, such as losing weight or getting better sleep. And users can now listen to a short, weekly “audio experience” to get their latest updates. Eternal was founded by Alex Mather, who previously founded the sports news publication the Athletic, which sold to the New York Times in 2022. The new venture, Mather told Fast Company, is a way to meld his editorial background with the world of health and fitness, of which he is particularly passionate. “It started with labs—we’d take a blood lab or DEXA scan, Mather says, “and we saw very few folks going in depth on the reports that we sent them. We were creating so much content for them, and they weren’t consuming it.” That, he says, was a revelation. “We quickly realized that most people want a story or a narrative,” Mather says. “They don’t want to look at numbers.” Thinking back on his experience of creating and launching successful podcasts during his time at the Athletic, Mather got an idea. “What if we could combine a health and fitness podcast into something more personalized? We had the first step,” he says. Get it on
