Nurse practitioner-owned primary care practice network Duet secured $15 million in series A funding to expand its clinic network and grow its partnerships and team.
Kairos led the funding round, with participation from Lerer Hippeau.
Kairos co-founder and co-CEO Alex Fiance said in a statement the company is “one of those rare businesses where everybody wins.”
“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,” Fiance said. “We believe Duet has the potential to reshape care across the country in a highly scalable way and are excited to help fuel their growth.”
Duet is the largest network of independent NP-owned primary care practices in the U.S., the company says. It helps practices earn compensation through its various partnerships with insurers, including Anthem, Cigna and Centene.
Duet Founder and CEO Jonathan Goldberg told Fierce Healthcare the company’s platform “combines practice advisors with AI-powered tools” to offload administrative work and give NPs more time for patient care.
“Our technology identifies people who are drifting out of care and gets them scheduled. It threads together patient data ahead of every visit, so an NP knows who is at risk and what to focus on,” Goldberg said. “And we help extend care into the home for those who need extra attention with remote technology and wraparound support.”
Goldberg continued, “There’s a lot stacked against small practices. Our mission is to help NPs show up for people that the system has overlooked.”
Patients visiting Duet clinics had an overall NPS of 92 across approximately 400,000 visits a year, Goldberg said.
“Patients often comment that this is the first time they felt heard, had someone take the time to read through their chart, or had a condition diagnosed that other clinicians had dismissed,” Goldberg said. “The clinical results follow from that. Practices that join Duet see preventive screenings for conditions like breast cancer and colon cancer rise 30%, and ER visits fall 20%. We also bring back 25% of the patients who are unengaged, and those are the patients who tend to end up worse off.”
The company has raised $22.5 million to date and works with more than 130 clinics across 21 states, executives say.
Goldberg said the company plans to use the fresh capital in three main ways: serve more clinics, deepen its value-based care partnerships with insurers and add engineers to its team. He added that Duet is launching an accelerator program in 2027 to help clinics “start strong.
Alongside the funding round, Duet announced it plans to launch the first-ever NP-led Medicare Accountable Care Organization (ACO) in 2027.
NPs will design and govern the company’s new model, which Goldberg says will allow practice owners to maintain “their autonomy while getting the technology and resources to strengthen their care.”
“NPs already practice prevention first, and this gives them a way to be recognized for it,” he said.
