Company profile
researched Aug 2026One Medical was launched in San Francisco in 2007 by physician and serial health-technology entrepreneur Tom X. Lee. Its management company, 1Life Healthcare, had been incorporated in Delaware in 2002 and operates affiliated physician-owned professional corporations through administrative-services agreements. The model layers an annual consumer or employer-sponsored membership on top of insurance-billed clinical care, health-network PMPM payments, employer onsite-service fees and, after the 2021 Iora Health acquisition, capitated Medicare revenue. One Medical went public on Nasdaq in January 2020 and was acquired by Amazon for $18 per share in February 2023. Amazon subsequently integrated Amazon Clinic as One Medical On-Demand Care, discounted membership for Prime customers, reorganized healthcare leadership, and launched a record-aware agentic Health AI assistant in 2026.
Founding story
Tom X. Lee, an internist who had co-founded clinical decision-support company Epocrates, started One Medical in 2007 to redesign primary care around easier access, longer appointments, calmer offices, salaried clinicians and consumer technology. Lee led it for about a decade before Amir Dan Rubin became CEO in 2017.
Business model
Hybrid care delivery and practice-management platform. 1Life provides technology, brand, billing, offices and administrative services to physician-owned professional corporations; the clinical entities provide care. Revenue combines subscriptions, insurance reimbursement, PMPM and capitated contracts, employer services and direct-pay telehealth.
Consumer annual memberships; discounted employer-sponsored memberships; patient/insurer fee-for-service billing for scheduled care; health-network PMPM partnership revenue; employer onsite-service fees; Medicare Advantage/CMS capitation and risk revenue inherited through Iora; and no-membership message/video visit fees.
Traction
At year-end 2022, immediately before acquisition, 1Life reported 836,000 members (796,000 consumer/enterprise and 40,000 at-risk), more than 9,000 enterprise clients, 221 medical offices in 27 U.S. markets and $1.046 billion of annual revenue. It was still loss-making, with a $112.4 million fourth-quarter operating loss and $36.9 million adjusted EBITDA loss. Amazon no longer discloses standalone financials.
Latest developments
Amazon launched One Medical Health AI in January 2026 and expanded the agent across Amazon surfaces in March. The assistant uses permitted health records, labs and medications for guidance and actions with clinical escalation. Dr. Roy Schoenberg became head of Amazon Health Services on July 1, 2026; Andrew Diamond leads One Medical Clinical Care Delivery within the reorganized structure.
▸Full profile — market position, technology, go-to-market, geography, history, ownership, risks & controversies
Market position
One of the best-known scaled U.S. technology-enabled primary-care platforms. Competitors span traditional physician groups, health-system practices, CVS Oak Street/MinuteClinic, ChenMed, Carbon Health, Forward, concierge practices and virtual-care vendors.
Combines a premium consumer experience and salaried primary-care teams with physical clinics, 24/7 virtual access, employer distribution, health-network integration and Medicare value-based care. Amazon adds Prime distribution, pharmacy, consumer logistics, technology and AI.
Technology
Mobile and web scheduling, secure clinician messaging, virtual visits, prescription renewals, records and care plans; proprietary practice workflow and population-health systems; and, since 2026, a HIPAA-oriented agentic Health AI assistant grounded in available medical records, labs and medications that can explain results, book visits and escalate to clinicians.
Go-to-market
Direct-to-consumer membership, Amazon/Prime cross-selling, employer benefits, health-system partnerships, insurer coverage, clinics in dense metropolitan markets, onsite employer practices and nationwide virtual care.
U.S. consumers and families; employers buying a primary-care employee benefit; health systems and health plans; Medicare and Medicare Advantage populations; and patients seeking one-time virtual treatment.
Commercial consumer and enterprise members, at-risk Medicare members, enterprise clients, health networks, Prime members, and pay-per-visit patients.
Geography
United States. The pre-acquisition network had 221 offices in 27 markets; membership includes nationwide 24/7 virtual access, while full in-person benefits depend on proximity to a One Medical location.
History
1Life Healthcare incorporated in Delaware in 2002 and the One Medical service launched in 2007. The company raised successive rounds from Benchmark, Oak, DAG, Maverick, GV, J.P. Morgan and others; Carlyle invested up to $350 million in 2018, including $220 million of primary capital and $130 million of secondary purchases. 1Life completed a $281.8 million IPO in January 2020. It acquired Medicare-focused Iora Health for roughly $2.1 billion in stock in September 2021. Amazon announced a $3.9 billion acquisition in July 2022 and closed it on February 22, 2023. Amazon integrated One Medical with Prime and Amazon Clinic, reorganized health operations after 2024-25 cuts and executive departures, appointed Roy Schoenberg head of Amazon Health Services in July 2026, and launched Health AI in 2026.
Ownership
Wholly owned by Amazon.com, Inc. following the February 2023 acquisition of 1Life Healthcare for $18 per share, approximately $3.9 billion including net debt.
Risks & controversies
The business carries medical-liability, patient-safety, privacy, clinician-capacity and reimbursement risk. A 2021 U.S. House investigation criticized One Medical's COVID-19 vaccine administration and membership promotion. The Amazon transaction drew competition and health-data privacy concerns. Amazon cut healthcare jobs in 2024 and reports alleged untrained call-center handling of urgent cases. A patient's family filed a wrongful-death lawsuit; One Medical later confirmed nine employees improperly accessed that patient's records and said they were terminated. A 2026 physician lawsuit alleged retaliation, discrimination and patient-safety failures; One Medical disputed the characterization. These litigation claims remain allegations unless adjudicated.
