Duet Raises $15M to Turn Nurse Practitioners Into Clinic Owners. Its Pitch Is Really About Small Business

NEW YORK — Most health tech startups sell software to hospitals or insurers. Duet is betting on a different customer: the nurse practitioner who wants to hang out a shingle and run a practice of her own.

The New York-based company, which calls itself the largest network of nurse practitioner-owned primary care practices in the U.S., announced a $15 million Series A on Thursday. The round was led by Kairos, with participation from Lerer Hippeau, and brings Duet’s total funding to $22.5 million.

What Duet Does

Duet doesn’t own the clinics. Nurse practitioners (NPs) do. Duet supplies what a solo owner usually lacks: billing, credentialing and payer contracting, plus practice advisers and software, according to MobiHealthNews. Its AI tools flag patients who have fallen out of care, help get them back on the schedule and surface issues for clinicians to address before a visit.

The company says its network spans more than 130 clinics in 21 states and serves about 150,000 patients, many in rural and underserved communities. It works with insurers including Anthem, Cigna and Centene, Fierce Healthcare reported, and helps practices earn pay tied to the quality of care and patient outcomes, not just the number of visits. FinSMEs put the total patient spend covered at about $100 million.

“There’s a lot stacked against small practices,” founder and CEO Jonathan Goldberg told Fierce Healthcare. “Our mission is to help NPs show up for people that the system has overlooked.”

Goldberg also told the outlet that practices joining Duet see preventive screenings for conditions like breast and colon cancer rise 30%, ER visits fall 20%, and 25% of unengaged patients come back. Those are company figures, not independent findings. Duet was founded in 2023, according to MobiHealthNews.

Where the Money Goes

Duet said it will use the round three ways: bring more NP-owned clinics into the network, deepen its value-based contracts with insurers, and hire engineers to build out its automation tools. Goldberg told Fierce Healthcare that Duet will also launch an accelerator in 2027 to help new clinics “start strong.”

The bigger announcement may be what comes with it. Duet plans to launch what it calls the first-ever NP-led Medicare Accountable Care Organization (ACO) in 2027. An ACO is a group of providers that shares in the savings when it keeps Medicare patients healthy at lower cost, a model the company notes has historically been led by hospitals and large physician groups. Duet says NPs will design and govern it, letting independent practices take part in Medicare’s shared savings program while keeping ownership of their clinics.

“Duet is one of those rare businesses where everybody wins,” said Alex Fiance, co-founder and co-CEO of Kairos. “It reaches patients in need, helps clinicians become business owners, and brings costs down for the payers and the U.S. government by catching problems early.”

The New York Angle

Duet is headquartered here, and it’s the latest Lerer Hippeau-backed company on AlleyWatch’s daily funding report this week, alongside The Shadery’s $3 million seed. It’s also a reminder that New York is one of the states where NPs can own and run a practice on their own. Under the state’s Nurse Practitioner Modernization Act, NPs with more than 3,600 hours of practice experience can practice without a written physician agreement, and the state has extended that authority through July 1, 2030. Those with fewer hours still need a written collaborative relationship with a physician, according to the State Education Department.

Lessons for Founders

You don’t have to be in health care to take something from Duet’s model:

• Sell to the owner, not the system. Duet’s customer is a clinician who wants to be her own boss. Building tools for the people starting small businesses, rather than for the incumbents they compete with, can open a market the big players ignore.
• Bundle the boring stuff. Billing, credentialing and contracting are exactly the jobs that sink independent operators. A startup that takes those off an owner’s plate is selling time and survival, not features.
• Pool small players to get big-player terms. One clinic has little leverage with an insurer. A network of 130 does. The same logic powers buying co-ops, franchise systems and group health plans for small employers.
• Align your revenue with your customer’s results. Duet’s value-based contracts mean it does better when its practices do better.
• Know your regulatory runway. Duet’s model rests on state rules that let NPs practice independently. If your business depends on a law or a license, track its expiration date the way you track your cash.

For New York’s own aspiring clinic owners, the round is a signal that investors see independent practice as a business worth backing, not just a calling.
