Cityblock Health

What Cityblock Health does

Cityblock Health is a value-based, technology-enabled healthcare provider founded in 2017 as a spinout from Alphabet's Sidewalk Labs, headquartered in Brooklyn, NY. The company delivers integrated primary care, behavioral health, social care, and urgent care services to Medicaid and dual-eligible populations across 11 or more U.S. states, operating 12 named Community Hub clinic locations plus in-home and 24/7 virtual care modalities. Services are rendered through Community Health Partners drawn from the communities served, supported by physicians, behavioral health specialists, clinical pharmacists, and care coordinators.

The company's care delivery is layered on proprietary AI and machine learning systems used for care coordination, triage, member outreach, agentic AI-driven member engagement, predictive population health analytics, NLP-based clinical documentation and coding, and AI-streamlined Long-Term Services and Supports assessments. Cityblock has published governance frameworks including a six-principles approach to responsible AI in Medicaid and a "Medicaid + AI: A New Standard for Innovation" report. Supporting programs include Hospital to Home (transitional care), Pediatrics (North Carolina), and an LTSS offering for high-cost, high-need members.

Cityblock operates a B2B2C model that does not bill members directly. Revenue is generated through capitated and risk-sharing value-based contracts with Medicare and Medicaid managed care organizations — including Molina Healthcare, UnitedHealthcare Community Plan, Aetna, Centene subsidiaries (Sunshine Health, Buckeye), Healthfirst, BCBS North Carolina, Tufts Health Plan, Fidelis Care, Alliance Health, and Meridian — under which attributed members receive Cityblock services at no out-of-pocket cost. The company has raised over $800 million in venture funding across rounds led by SoftBank (Series D, $400M, $5.7B post-money in September 2021) and reports over $1 billion in annual recurring revenue serving more than 100,000 Medicaid and dual-eligible members.

Revenue model

1. Value-Based Care - Total Cost of Care Contracts: Cityblock takes on the total cost of care for members and is paid for the overall health of the patient population rather than per-service billing. The company assumes financial risk for managing the healthcare costs of attributed Medicaid and dually eligible members through capitation or risk-sharing arrangements with health plan partners.
2. Health Plan Partnership Revenue: Revenue is generated through contracts with Medicare/Medicaid managed care organizations. Cityblock's services are typically included in the benefits of health plan members at no additional out-of-pocket cost. The company receives capitated payments or shared savings based on care quality and cost outcomes.

Core offering

Services are delivered through Community Hub clinics, in-home visits, and 24/7 virtual care modalities under capitation and risk-sharing contracts with Medicare/Medicaid managed care plans.

Product overview

Cityblock Health operates as a value-based, tech-enabled healthcare delivery platform rather than a traditional SaaS product. The core offering is an integrated care platform combining primary care, mental health services, social care, and urgent care — delivered through in-person clinic visits, in-home care, and 24/7 virtual/telephonic modalities. Supporting programs include Hospital to Home (transitional care), Pediatrics (in North Carolina), and Long-Term Services and Supports (LTSS) for members with complex needs. The platform serves Medicaid and dual-eligible populations across multiple U.S. states, positioning AI as an enabling layer for care coordination, outreach automation, and clinical decision support rather than a standalone product.

Direct peers

• Oak Street Health: Value-based primary care provider serving lower-income and Medicare-eligible populations with integrated care teams. Acquired by CVS Health for ~$10.6B in 2023. Highly comparable to Cityblock's care model, though Oak Street skews Medicare Advantage and operates owned clinic footprint more heavily than Cityblock's in-home/community hub mix.
• Cano Health: Value-based care provider focused on Medicare and dual-eligible populations with primary care, pharmacy, and social services integration. Directly comparable to Cityblock in serving complex dual-eligible patients through capitated contracts, though Cano has faced significant financial distress and footprint contraction since 2023.
• Agilon Health: Tech-enabled value-based care platform partnering with independent primary care physicians to take on Medicare total cost of care risk. Public company (AGL). Closely comparable in operating model — partnering with MCOs and PCPs under capitation — though Agilon is predominantly Medicare Advantage focused rather than Medicaid.
• ChenMed: Family-owned, value-based primary care group serving low-income seniors through owned clinics with dedicated physician panels and integrated specialty services. Comparable to Cityblock in serving complex, dual-eligible seniors with intensive physician-led care, though ChenMed is private and Medicare Advantage focused.
• InnovAge Holding Corp. Public PACE (Program of All-Inclusive Care for the Elderly) provider delivering integrated medical, behavioral, and social services to dual-eligible seniors. Strongly comparable to Cityblock's whole-person care model and dual-eligible focus, with similar LTSS/medical integration serving a complex population.
• Privia Health: Physician enablement and medical group platform operating value-based care arrangements across multiple payer types including Medicaid. Public company (PRVA). Comparable in multi-payer, multi-state value-based care delivery, though Privia's model is more multi-specialty/PCP enablement than Cityblock's Medicaid-focused integrated care.
• Landmark Health: In-home medical care provider serving complex, polychronic patients typically attributed through Medicare Advantage and Medicaid managed care plans. Acquired by Optum (UnitedHealth Group). Highly comparable to Cityblock's in-home care delivery modality and complex-population focus.

Emerging players

• Aledade: Value-based care network enabling independent primary care practices to enter risk-bearing contracts with Medicare, Medicaid, and commercial payers. Comparable business model logic (capitation, tech-enabled care coordination) though Aledade is a physician-enablement platform rather than a direct provider like Cityblock.
• P3 Health Partners: Value-based care company focused on Medicare Advantage populations with a PCP-led, technology-enabled model. Public company (PIII). Comparable in value-based primary care delivery serving complex senior populations, though at a smaller scale and Medicare Advantage tilt versus Cityblock's Medicaid core.

Broad incumbents

• Astrana Health: Public value-based care management organization (formerly Apollo Medical) providing care delivery, IPA management, and population health services across Medicare, Medicaid, and commercial populations. Public company (ASTH). Comparable in value-based care infrastructure and payer partnerships, broader across lines of business than Cityblock.
