Duet Raises $15M to Support Independent NP-Owned Clinics

Duet is raising capital around a network whose clinics remain independently owned. The New York company supplies the business support, technology and insurer relationships that help nurse practitioners run primary care practices, concentrating shared work around owners who continue caring for their own communities.

Its $15M Series A, announced November 12, 2026, was led by Kairos, with Lerer Hippeau participating. Duet reports $22.5M in total funding and a network of more than 130 clinics across 21 states. The investment will support additional clinics, deeper value-based insurer partnerships and engineering, alongside plans for a nurse practitioner-led Medicare Accountable Care Organization in 2027.

That combination gives the financing an assignment beyond distributing another software tool. Duet wants independent practices to share enough operating capacity to negotiate and perform together, while preserving the ownership that makes those practices independent in the first place.

What Duet's Series A funds around the clinic

Founder and CEO Jonathan Goldberg is building for clinicians who also have a business to run. Duet's practice support offering follows that business through launching, scaling and operating an established clinic. Early work includes planning, credentialing and setting up an electronic health record system; later support extends into billing, coding, patient recall and financial operations.

The sequence matters. A practice opening its doors needs different help from one trying to understand why a busy schedule has produced disappointing collections. Duet organizes its services around those stages and includes a practice advisor, making the relationship more involved than a software subscription a clinician is expected to configure alone.

Duet says its tools integrate with a practice's existing EHR. For an owner, keeping familiar clinical software while adding business support can reduce the amount of change required to seek help. The useful question becomes which tasks the outside partner takes over, what information comes back and whether the owner can act on it.

The financing supports expansion of that operating model. More participating clinics create work in onboarding, service delivery and engineering, with each new relationship bringing its own existing routines. Growing the network means making the shared support useful inside another independently run business, where a late claim or missed appointment has an immediate local consequence.

Why insurer contracting changes the ownership equation

Duet's insurer offering connects independent practices through a common network. Its published model brings care-gap alerts into providers' schedules, uses a care management team to reach higher-risk patients between visits and combines information on utilization, quality measures and patient attribution.

Those functions connect the day's clinical work to the information an insurer uses to understand a patient population. An alert has to arrive where the clinician works; an outreach effort has to result in a useful patient contact. Combining the information across practices also gives the network a way to describe what its members are doing together.

In its financing announcement, Duet names Anthem, Cigna, Centene and Molina as insurers contracting with the network. The company says the arrangement gives small clinics access to value-based contracts that would be difficult to secure individually, and that Duet absorbs financial risk in many of them. That places an economic responsibility alongside its administrative role.

For the practice owner, the attraction is a relationship between autonomy and bargaining capacity. Joining a common contracting organization can bring opportunities that depend on collective scale, but the everyday delivery still happens through individual clinicians and their teams. The operating challenge is keeping those two levels connected as another clinic joins and another insurer agreement takes effect.

Bookkeeping makes the business visible to its owner

A separate customer account from Layer shows how far Duet's work extends beyond claims. The companies partnered on Duet Bookkeeping, an embedded service designed for nurse practitioner practices. Layer describes human bookkeepers categorizing transactions and supporting practice owners inside the broader Duet experience.

Collecting reimbursement and understanding the resulting business are related jobs. An owner needs to know how money moves through the practice before deciding whether to add capacity, change spending or seek further help. Putting bookkeeping near billing and practice management gives Duet another point of contact with those decisions, without making every clinical owner become an accounting specialist.

Layer identifies Duet as founded in 2023, with headquarters in New York City. Lerer Hippeau's investment account also places the company in New York and explains its interest in tools supporting providers as they become clinic operators. The investor's perspective is useful evidence of the financing thesis, with the firm's financial interest kept in view.

Duet's current leadership includes Jonathan Goldberg, COO Alicia Korpi Ortiz, CFO Charles Donner, ACO Chief Medical Officer Efrat LaMandre and Chief Clinical Officer Wendy Wright. The mix reflects the work surrounding the network: clinical leadership, financial operations and the practical demands of supporting independently owned practices.

The Medicare ACO adds a shared performance obligation

Duet plans to launch a nurse practitioner-led Medicare ACO in 2027. Its ACO program materials describe a model intended to let NP-owned practices participate in shared savings while retaining ownership. The financing announcement presents that launch as a plan; it does not establish a completed Medicare launch or a particular approved participation track.

CMS describes the Shared Savings Program as a way for groups of providers to become accountable for the quality, cost and experience of care for an assigned Medicare population. An ACO may receive performance payments when it delivers qualifying care and achieves savings. The work reaches across encounters, making coordination and reliable population information part of the financial arrangement.

Duet reports higher preventive screening rates and fewer emergency room visits among participating practices, with increases of 30% and reductions of 20%, respectively. These are company-reported comparisons; the announcement does not provide an independently audited study design or enough detail to treat them as guaranteed results for another clinic. They indicate the kinds of activity Duet wants its infrastructure to support.

As the Medicare effort develops, the owners joining it will still be running the practices that see those patients. Duet's engineers, advisors and contracting team will be working around that continuing responsibility, helping a local clinic participate in an arrangement measured across a much larger population.
