Company profile
researched Aug 2026DUOS (legal name DUOS Living, Inc.) operates a member engagement and performance platform for health plans, positioning itself as infrastructure that closes what it calls the "follow-through gap" between benefit and program design and actual member action. Its platform is organized into three solutions: DUOS Activate, combining digital-first outreach with live human support to move members to completed care actions such as Annual Wellness Visits and HEDIS gap closure; DUOS Enroll, which screens and enrolls members in government programs including Extra Help/Low-Income Subsidy, SNAP and Medicaid during routine interactions; and DUOS Optimize, a provider-side engine that detects documentation and medication-safety gaps and engages prescribers directly to recover RxHCC revenue.
The platform aggregates more than 100,000 Medicare benefits, local community resources and government programs together with plan-specific data, and uses an AI-driven recommendation engine to surface the best-fit resource for an individual. Members reach DUOS through a digital self-service account or by phone (staffed 9am-9pm ET, Monday-Friday), and the service is made available to members at no cost through their health insurance plan. A provider-facing offering gives clinical and operational teams tools to surface social-determinants and care resources, support transitions of care pre- and post-discharge, and coordinate campaigns with patient cohorts to improve quality ratings. Use cases cited include retaining coverage through Medicaid redetermination, LIS enrollment, scheduling Annual Wellness Visits and mail-order pharmacy enrollment.
Founding story
DUOS was started in 2020 after its founders observed that older adults in their own families had access to health plan benefits, government programs and care resources but did not use them or know how to use them — framed by the company as a follow-through problem rather than an access problem. The initial model paired older adults one-to-one with a dedicated healthcare navigator, a "duo" intended to cut through confusion and connect them to earned benefits. The company describes founder pairs including Karl and his father Greg, Anne and her mother Linda, Jacques and her father Jerry, and Kristen and her mother Cindy. Concluding that the gap was systemic rather than individual, the company shifted to partnering directly with health plans to scale the same human connection.
Business model
DUOS contracts with health plans (and, per earlier company statements, providers and employers), which make the service available to their members at no cost to the member. The company positions its platform as performance infrastructure tied to plan outcomes such as completed preventive care actions, quality/Stars performance, government program enrollment value, risk-adjustment (RxHCC) documentation and member retention.
Revenue is generated from health plan, provider and employer partners rather than from members; the service is free to members through their insurance, though DUOS notes it may surface some fee-based services (such as meal delivery) that members can choose to use.
Traction
Company-reported outcomes include an 85% Annual Wellness Visit completion rate among activated members, approximately $400 in-year LIS value per member per year, more than $35 million in qualified RxHCC opportunities per 100,000 members, and 90% member retention during network disruptions relative to unengaged populations. The 2023 funding announcement cited rapid customer growth, and the company says it can support members across the United States.
Latest developments
In October 2025 DUOS announced a $130 million strategic growth investment led by FTV Capital with participation from Forerunner Ventures, its earliest institutional investor, earmarked for AI capability development and expansion across Medicare Advantage, Medicaid and ACA marketplace plans. Jenn Kerfoot was promoted to President of Market Operations, and FTV Capital's Alex Mason (Partner) and Justin Levine (Vice President) joined the board. In February 2026 Kerfoot was named to Modern Healthcare's 40 Under 40 list, and in March 2026 DUOS was named to Fierce Healthcare's 2026 Fierce 15. The company website also references an acquisition of a closed-loop engagement capability for the "final mile."

Market position
DUOS competes in senior-focused care navigation and health plan member engagement, differentiating itself from analytics platforms that do not contact members directly. Coverage notes broader investor momentum in senior care technology, citing companies such as The Helper Bees, SafelyYou and Tombot. DUOS was named to Fierce Healthcare's 2026 Fierce 15.
The company frames its distinction as closing the loop on member action rather than stopping at outreach or analytics: it connects members directly, combines digital self-service with live human support, and reports completion-based metrics (for example an 85% Annual Wellness Visit completion rate among activated members) rather than engagement alone. It also spans both member-side activation and provider-side documentation and medication-safety workflows.
Technology
An AI-powered recommendation and engagement layer sits on top of an aggregated database of more than 100,000 Medicare plan benefits, community resources and government programs, plus plan-specific data such as Stars measures, Annual Wellness Visit status and social-determinants gaps. The company states its AI learns from member behavior and intent to identify the most relevant next action and to time digital or human support, and that provider-side clinical intelligence generates direct prescriber alerts for documentation and medication-safety gaps.
Go-to-market
Direct enterprise sales to health plans and providers via demo requests, complemented by content and whitepaper distribution; member acquisition occurs through plan sponsorship, with digital sign-up and an inbound toll-free line. Partnerships such as senior transportation with Uber Health have been used to extend supplemental benefit delivery.
Medicare Advantage, Medicaid and ACA marketplace health plans; healthcare providers and their member- and patient-facing teams; employers communicating benefits to aging employees. End users are older adults, Medicare beneficiaries and their caregivers.
Geography
United States, with member support delivered online and by phone nationwide; member testimonials reference Louisiana, California, Kentucky and Michigan. Coverage describes the company as Minneapolis-based, and the 2025 funding is intended to expand operations across Medicaid, Medicare Advantage and ACA marketplace plans in the U.S.
History
Launched in 2020 with a human-powered navigation service for aging needs, DUOS expanded into a suite of technology and engagement products for health plans, providers and employers. It raised roughly $6 million in seed capital in 2021, a $15 million Series A in April 2022, and an additional $10 million in June 2023 from strategic and impact investors, bringing total funding to more than $33 million at that point. In October 2025 the company announced a $130 million strategic growth equity investment led by FTV Capital, alongside the promotion of Jenn Kerfoot to President of Market Operations and the addition of two FTV Capital investors to its board. Subsequent recognition included Kerfoot's inclusion on Modern Healthcare's 40 Under 40 list and DUOS' selection for Fierce Healthcare's 2026 Fierce 15.
Risks & controversies
Performance figures such as completion rates, per-member LIS value, RxHCC opportunity and retention are company-reported and not independently verified in the available material. The business is concentrated in government-sponsored health insurance programs (Medicare Advantage, Medicaid, ACA marketplace), exposing it to regulatory and plan-funding changes, and coverage notes health plans face rising pressure on outcomes, costs and member churn.
