What You Should Know
- Duet, the largest network of nurse practitioner-owned primary care practices in the United States, announced a $15M Series A funding round, bringing its total capital raised to $22.5M.
- Kairos led the financing round, with participation from Lerer Hippeau, to expand Duet’s clinic network, deepen value-based payer partnerships, and grow its software engineering team.
- Duet plans to launch the first-ever nurse practitioner-led Medicare Accountable Care Organization (ACO) in 2027, giving independent NP-owned practices direct access to federal shared savings programs while preserving practice autonomy.
- Operating across more than 130 clinics in 21 states and serving approximately 150,000 patients across 400,000 annual visits, Duet focuses heavily on rural and underserved communities where more than 100 million Americans lack adequate primary care access.
Practice Enablement: Automating Administrative Overhead for Independent Owners
Duet’s operating model combines back-office administrative infrastructure with predictive clinical software, allowing nurse practitioners to retain full practice ownership while offloading non-clinical burdens. The company’s artificial intelligence tools continuously scan patient rosters to identify individuals who have fallen out of routine care and automate appointment scheduling. Ahead of each clinical encounter, the software surfaces high-priority clinical gaps and chronic disease risks directly within the workflow, while Duet’s centralized operations team manages medical billing, provider credentialing, and commercial payer contracting.
By aggregating over 130 independent clinics into a single, vetted clinical network, Duet secures enterprise value-based contracts with major national insurers—including Anthem, Cigna, Centene, and Molina—that individual clinics could never negotiate independently. Across many of these arrangements, Duet absorbs the downside financial risk, currently managing approximately $100 million in total patient medical spend.
Clinical and Financial Performance Across 400,000 Annual Visits
Early operational data across Duet’s network demonstrates that pairing independent clinical ownership with proactive patient outreach yields measurable improvements in both care quality and practice profitability. Across 400,000 annual patient visits, Duet clinics have achieved a patient Net Promoter Score of 92, substantially outperforming the broader healthcare industry benchmark of 40 to 70.
Clinically, practices joining the Duet network have recorded a 30 percent increase in preventative screenings for breast and colon cancer alongside a 20 percent reduction in emergency room utilization. Automated outreach workflows have successfully re-engaged 25 percent of previously lapsed patients, capturing high-risk individuals before chronic conditions escalate into acute hospitalizations. Financially, participating nurse practitioners operating under Duet’s alternative payment contracts have increased practice revenue by 25 to 50 percent through shared quality and cost incentives. In New Hampshire, Duet’s anchor market, the network outperformed regional peers on total cost of care by 19 percent, generating substantial shared savings.
Launching the First Nurse Practitioner-Led Medicare ACO in 2027
Building on its commercial payer traction, Duet plans to establish the nation’s first nurse practitioner-led Medicare Accountable Care Organization in 2027. Historically, Medicare Shared Savings Program entities have been dominated by large hospital systems and multi-specialty physician groups. Duet’s ACO will be designed and governed specifically by nurse practitioners, allowing independent rural and community practice owners to participate in federal shared savings models without surrendering clinical governance or equity to hospital consolidators.
Jonathan Goldberg, Founder and Chief Executive Officer of Duet, emphasized that empowering clinicians as business owners is essential to closing primary care deserts. Goldberg noted that while nurse practitioners already deliver a substantial share of primary care and command deep patient trust, systemic barriers have historically kept them from scaling independent clinics, adding that Duet enables clinicians to transition from an employed workforce into enduring community practice owners.
