Eternal

Eternal (Eternal Life, Inc.) operates a consumer health, fitness and longevity platform aimed at physically active, "mostly healthy" adults. Members connect wearables and apps such as Apple Health, Oura, Strava, Hevy and Garmin and upload blood labs or DEXA scans; the service then tracks weekly goals across sleep, movement, cardio, strength and stress and produces a weekly personalized podcast episode plus daily coaching texts that interpret results and prescribe interventions.

The platform bundles several components: "The Perfect Week" adaptive weekly plan, an AI assistant marketed as Eternal Intelligence that answers health, fitness and aging questions and monitors wearable data, ordering and interpretation of blood panels, hormone, heart, thyroid and cancer-screening tests, nutrition and sleep coaching, mental-performance tracking, and access to physicians, dietitians, trainers and coaches who have the member's data in context. A concierge membership tier includes items such as dietitian consultations, a core blood panel and medical visits. In-person services — advanced diagnostics, personal training and physical therapy — are offered in New York and San Francisco, with additional locations described as planned. At launch the company described sport-specific care teams for runners, cyclists and triathletes and gender-specific practices, supported by comprehensive diagnostics including bloodwork, DEXA scans, VO2 max and lactate threshold testing, and strength, power, mobility and balance tests.

Founding story

Founder Alex Mather previously co-founded The Athletic, which was sold to The New York Times in 2022, and earlier worked on products for endurance athletes at Strava. After the sale he focused on his own fitness and, motivated by a fear of aging and death and by the difficulty of separating useful health tactics from noise, started Eternal to give proactive people a coherent long-term health strategy.

Business model

Consumer subscription/membership. Eternal sells a membership (including an "Eternal Concierge" tier) that bundles software, AI coaching and personalized media with clinician and coach access, diagnostics and in-person services; membership inclusions listed include dietitian consultations, a core blood panel and medical visits.

Recurring membership fees for the digital product and concierge care; the founder described building a consumer subscription business intended to be retained over a member's lifetime.

Traction

The company's site states it is "trusted by thousands" of members; a concierge membership and in-person services in two cities are offered.

Latest developments

Eternal markets a full consumer membership product including the weekly personalized podcast, daily texts, Eternal Intelligence, lab and cancer-screening ordering, and the Eternal Concierge tier, with in-person care available in New York and San Francisco.
