Marathon Health

What Marathon Health does

Marathon Health is a private, Indianapolis-headquartered advanced primary care company founded in 2004 that delivers value-based healthcare services to self-insured employers, labor unions, health plans, and brokers across the United States. Following its February 2024 merger with Everside Health, the combined entity operates more than 720 health centers across 41 states with virtual care coverage in all 50 states, serving over 2.5 million patients. Its care model emphasizes relationship-based, preventive primary care delivered through onsite, nearsite, and network health centers as well as 24/7 virtual urgent care, supported by modules for mental health, musculoskeletal, occupational health, population health management, value-driven specialty referrals, lifestyle management, and medication management.

The platform is anchored on the athenahealth electronic health record system, into which Avo's AI documentation and chart review tools were integrated in late 2025 to automate clinical workflows across the network. A strategic partnership with Lantern extends the offering into value-based specialty care coordination, with pilot results showing 37–100% increases in successful referrals and 53% average savings versus standard PPO rates. The company reports 95% employer client renewal rates, provider retention above 90%, and $1,100 in average annual savings per engaged member.

Commercially, Marathon Health sells enterprise contracts to self-insured employers and unions on a subscription basis with annual billing and customized pricing tied to population size, deploying consultative field sales and ROI-driven proposals. Revenue is generated through employer- and union-sponsored contracts rather than traditional fee-for-service insurance billing, with measurable outcome-based components including $93 per member per month in healthcare cost reduction for engaged members. The company is backed by General Atlantic, New Enterprise Associates, and a prior $30 million Goldman Sachs round, and was recognized as Best in KLAS in 2024 for Employer-Sponsored Healthcare Services.
