A radical reimagining of healthcare

Our mission is to advise and accompany forever athletes on their pursuit of a fuller, healthier, more active life.

Benchmarked for athletes.
Personalized for you.

For active people, there’s a big difference between what’s clinically in range and what’s optimal. We use targeted diagnostics to assess everything from your systemic health to performance indicators like inflammation, muscle damage, and hormone markers. Then we fine-tune your nutrition protocols to keep you performing at your best.

Our Story

Founded by Alex Mather, co-founder of The Athletic and one of Strava’s first product leaders, Eternal was created for people who can’t imagine a life without being active. Combining extensive diagnostics that go way deeper than a standard physical with a guided plan to help people conquer their fitness, health, and aging goals, Eternal is creating a new standard of care for both elite and lifestyle athletes.

Eternal is backed by Lightspeed Venture Partners, Courtside Ventures, Treble Capital, Next Ventures, & more.

Eternal is reimagining health care for people who care about staying active, bringing the kind of obsessive, athlete-focused attention the pros get to the rest of us. It’s a radical new approach, and it’s changing the equation when it comes to aging and athletic performance.”
