Patient Voice Agents

AI patient billing and revenue cycle platform focused on the patient responsibility portion of provider revenue, which the company notes has risen from roughly 5 percent of provider revenue in 2010 to about 20 percent today and is projected toward 30 percent by decade end. Billie is the AI billing agent, engaging patients across chat, text, email, and voice to answer billing questions, explain what is owed, and take payment, with the company stating it handles the majority of cases and staff step in for exceptions. The platform covers intelligent statements, personalized outreach, payment plans, card on file, autopay, and refunds, plus an eligibility and benefits agent. Positioning is deliberately complementary rather than displacing: the company frames the EHR as the system of record and itself as the system of action on top of it. Integrated with more than 20 leading EHRs via API or FHIR, with a bidirectional Epic integration listed in Connection Hub on the Epic Showroom as of July 2026. Reported footprint is more than 3,000 healthcare facilities with over $1 billion in patient payments processed. Customer reported results include collections increases in the 75 to 300 percent range and average days to collect as low as 12.6. Holds HIPAA, SOC 2 Type 2, PCI DSS, and HITRUST i1 compliance. Backed by Sapphire Ventures and Y Combinator; CEO and co-founder Levon Brutyan.

Voice AI care management for health plans and at risk providers, originating in vocal biomarker research for detecting depression and anxiety and now productized as Sage, an AI care manager. The distinguishing technical claim is the Empathy Engine, patented vocal biomarker technology trained on millions of live clinical patient calls, which reads emotional state from voice in real time rather than only transcribing words, and adapts tone and approach accordingly. Sage conducts inbound and outbound member calls covering health risk assessments, post discharge follow up, risk profiling, care gap closure, program enrollment, medication reminders, and triage, and is positioned explicitly as added staffing capacity rather than a chatbot, reserving clinicians for complex high touch interventions. Integrations include Salesforce Health Cloud and, through an April 2026 partnership with HealthEdge, the Care Solutions suite drawing on GuidingCare member data and returning outcomes to the platform. Company reported figures, which it acknowledges are not independently audited, include roughly 60 percent reduction in administrative tasks, 6x faster program enrollment, and 4x return on investment. Named customers per the company website include UnitedHealth Group, Aetna, Duke Health, and Highmark. Founded 2017 by CEO Mainul Mondal; approximately $75 million raised including a $45 million round in June 2025 co-led by Salesforce, Khosla Ventures, and CVS Health Ventures.

Health benefits navigation and care platform for self insured employers and health plans, indexed for its AI navigation layer with the surrounding care services as context. WayFinding is a generative AI experience launched in 2024 and scaled through 2025, combining benefits navigation, clinical guidance, and care access in one interface, delivering tailored recommendations from a member's own history so a member can determine what is covered, what it will cost, and where to go. Agentic capabilities were added in January 2026. The company completed a $621 million merger with Accolade in April 2025, taking the formerly NASDAQ listed company private and combining WayFinding and the Cancer Care, Surgery Care, Weight Health, and pharmacy benefit experiences with Accolade's health advocacy, expert medical opinion, virtual primary care, and its True Health Actions platform, which draws on employer data, health plan data, and electronic health records for targeted guidance. The combined organization reports serving more than 20 million members across more than 1,700 employer and health plan clients. Buyers should be clear that this is a hybrid: a substantial share of what is delivered is human advocacy, virtual clinical care, and second opinion services rather than AI. A $126 million Series D in May 2024 was raised specifically to build AI capability. Led by Glen Tullman.

Indexed for the AI capabilities inside the Doctolib platform rather than for the platform itself, which is context under this index's product scoping rule, and the first non US vendor treated this way. Doctolib is the dominant digital health infrastructure provider across France, Germany, and Italy, spanning appointment booking, practice management, and clinical records. Its ambient documentation capability, the Consultation Assistant, is built on technology from the June 2024 acquisition of Typeless, an EPFL and Idiap Research Institute spin off specializing in AI speech recognition, and uses large language models to convert spoken doctor patient dialogue into structured medical text including clinical notes and doctor letters. In November 2025 the company launched an all in one practice management product incorporating three AI assistants, including a telephone assistant that answers calls around the clock, categorizes inquiries, and transfers appointment bookings directly into the Doctolib system; the company reports practices can save up to ten hours per week on administrative tasks. That product launched for general practitioners, pediatricians, and gynecologists with additional specialties planned. The strategic significance is distribution: ambient documentation delivered inside the appointment and record workflow a practice already uses, which is a different competitive position from standalone scribes such as Nabla or Abridge. Note that European regulators treat ambient scribes as software as a medical device, with the UK MHRA classifying them accordingly, so regulatory posture differs from the US market.

Patient financial experience platform for hospitals, health systems, and physician groups, covering the part of revenue cycle the patient actually experiences: the bill. Cedar Intelligence is the AI decision engine personalizing billing journeys across channels, and Kora is the voice agent, launched April 2025 and developed with Twilio, trained on the company's proprietary billing data rather than a general model. Kora resolves common billing inquiries on first contact, explaining charges, identifying payment options, and connecting patients to financial assistance, with sentiment and tone detection, multiple language support including Spanish, and escalation to a live agent with full context when human judgment is required. One year in, the company reports Kora has handled nearly 400,000 patient calls across ten provider organizations spanning Epic and Cerner health systems, physician staffing groups, and large specialty groups, with Gastro Health alone accounting for more than 60,000 calls since September 2025. Kora Outbound extends the agent to proactive engagement of harder to reach patients. The company reports its platform data foundation exceeds one billion patient interactions. Its own published research is unusually pointed for a vendor: 40 percent of collectible dollars on its platform now come from uninsured patients, up 54 percent in three years, and it argues that billing experiences designed for financially stable patients are failing those under the greatest strain.

Healthcare data and agentic AI platform, described by the company as an agentic cloud for healthcare, built in three stages: data connectivity integrating Epic, Cerner, MEDITECH, and Allscripts with payer claims, pharmacy, lab, remote monitoring, and social determinants sources across a reported 80 million plus patient records; applications on top of that data; and now autonomous agents. Gravity is the underlying data platform, continuously trained on real world healthcare data including claims denials and edge cases, which the company argues gives each new agent institutional context at launch. Sara is the AI assistant line spanning insights, care management, and clinical documentation via Sara Scribe. A suite of pretrained voice enabled agents covers appointment scheduling, protocol intake, referral management, routine patient inquiries, prior authorization, care gap closure, hierarchical condition category coding, and transitional care management, supporting clinicians, care managers, risk coders, patient navigators, and contact center staff. The stated architectural claim is end to end workflow connection: a prior authorization agent can hand off to coding and denial management agents rather than each operating in isolation. Reports serving six of the top 10 US health systems and more than 130 healthcare organizations, with named customers including Kaiser Permanente, Ascension, and Trinity Health. Best in KLAS recognition across data and analytics, population health management, and CRM categories. Founded 2014; $675 million raised in total including a $275 million Series F, with investors including Kaiser Permanente and Banner Health.

Conversational AI agent platform built for healthcare since inception rather than adapted to it, spanning call centers, websites, SMS, and mobile apps. The architecture is deliberately hybrid: large language models combined with a proprietary conversational engine, small language models tuned for healthcare, and knowledge graphs purpose built for the domain, which the company positions as more controllable than a general model alone. Agents integrate through API into EHRs and CRMs to complete tasks autonomously, including registration, routing, scheduling, and prescription refills, with contextual transfer to a live human when needed, and all interactions captured in a Patient Intelligence Dashboard. The company reports resolving up to 85 percent of routine patient interactions, deployment across more than 45 to 50 US health systems, and over 30 million patients engaging with its agents. Named clients include Intermountain Health, Baptist Health, Hackensack Meridian Health, and Bon Secours Mercy Health, which also invested. Founded 2018 by Israel Krush and Rom Cohen as a Cornell Tech spinout with offices in New York and Tel Aviv; $95 million raised in total including a $45 million round in October 2025 led by Healthier Capital with ServiceNow Ventures participating. Named to Fierce Healthcare's Fierce 15 for 2026.

AI agent platform for healthcare operations, spanning patient access, revenue cycle, and care operations rather than a single workflow. Agents automate patient intake and registration, appointment scheduling, insurance eligibility verification, prior authorization, denial management, patient payment estimates, referral processing, and post visit follow up, each running a defined workflow end to end. Flow Builder is a no code interface that lets an organization's own IT and non technical staff build, train, and deploy agents, which places it alongside Bunkerhill and XCaliber as a build your own platform rather than a fixed product set. Integration is unusually pragmatic and is the stated differentiator: the company uses whichever method reaches the field, including APIs, RPA, and HL7, reading and writing structured and unstructured data across Epic, Oracle Health, MEDITECH, athenahealth, and payer portals. Named health system deployments include Intermountain, Trinity Health, and MUSC. Published customer results include a health system reaching 64 percent voice containment with roughly $360,000 annual savings, and an insurance FAQ voice assistant answering all inbound calls at a stated $4 saving per call. Backed by Greylock and ICONIQ Growth.

Hub of conversational AI agents for hospitals, operating across three orchestrated layers: triggers, where agents identify clinical gaps and risks from health assessments, prescriptions, and diagnostic findings; navigation, where agents qualify patients and guide care journeys; and revenue, where pending care is converted into booked services. Patients calling or messaging reach conversational AI with no menu and no IVR, and the agent accesses the real schedule to resolve the request end to end. After a visit an agent reads the medical record, identifies prescribed exams and consultations that were never booked, and proactively offers scheduling over WhatsApp, recapturing care that would otherwise be lost to follow up. Other agents confirm appointments with preparation guidance to reduce no shows. WhatsApp as the primary channel reflects the market: the company serves reference hospitals in Brazil and Mexico and is scaling across Latin America, which makes it one of the few vendors in this index built for a non US care and communication context. Pre seed stage; founded by Sergio Ricardo Santos.

AI native operating system for behavioral health clinics, combining a set of named AI workers with an integrated EHR, CRM, and revenue cycle management in one platform. Sarah, the admissions coordinator, answers inbound calls, texts, and faxes around the clock and verifies insurance in real time, with more than 100,000 patients booked reported. Emma, the clinical assistant, generates ICD-10 and CPT coded session notes within about 30 seconds and is reported to have supported more than 3 million patient sessions. Eric handles coding, claim scrubbing, submission, and denial management. Laura manages between visit engagement. The fully integrated platform launched April 2026, partners with athenahealth through the athenaOne Marketplace, and reports clinics booking 30 percent more patients with clinicians saving more than two hours daily, across hundreds of mid to large behavioral health clinics. Behavioral health operations are a distinct problem from general practice, and the specialization is the point. Backed by Y Combinator, Precursor Ventures, Pioneer Fund, Rebel Fund, and Expansion Venture Capital.

Patient communications platform with AI virtual agents across voice, text, and web, formerly WELL Health. Not to be confused with ArteraAI, a separate prostate cancer AI company at artera.ai. The Harmony platform coordinates agentic AI across the patient journey with staff able to take over at any point and full conversation history retained, covering self scheduling, intake, forms, referrals, and billing questions. Flows Agents apply natural language understanding to automate multi step patient conversations, and AI Co-Pilots assist staff with translation, message shortening, and conversation summaries. The company reports more than 1,000 provider organizations including specialty groups, federally qualified health centers, large IDNs, and federal agencies, roughly 2 billion communications annually across 109 languages, and engagement with 100 million patients a year. Artera Government Solutions serves the Department of Veterans Affairs, Department of Defense, and Indian Health Service sites. In May 2026 the company introduced an AI services model pairing the platform with its own build teams. Raised a $65 million growth round in December 2025.

AI voice agents for patient access and revenue cycle telephony. The distinguishing capability is direction: alongside patient facing calls for scheduling, intake, and billing questions, the agents call payers directly, navigating IVR trees, waiting on hold, and speaking with representatives to obtain benefits and prior authorization details when electronic eligibility transactions return incomplete data, then writing structured results back to the EHR or practice management system. Every call is automatically reviewed by AI for accuracy and compliance rather than by manual audit. The vendor reports reaching more than 150,000 healthcare providers and cites roughly three week implementation. Founded 2023; raised a $30 million Series A led by Andreessen Horowitz in 2026, following a $5 million seed.

Conversational AI for healthcare operations, indexed here for the HealthAI product line: voice, text, email, and chat agents that handle patient scheduling, reminders, refills, billing questions, and intake, booking directly into the EHR and handing off to staff when needed. The vendor reports 95 percent of patient inquiries handled without human intervention, support for more than 50 languages, and HIPAA and SOC 2 Type II compliance. The company's property management business is out of scope for this index.

Safety focused patient facing voice agents for non diagnostic clinical work: post discharge follow up, medication adherence, preoperative instructions, chronic care check ins, and screening outreach, conducted by voice and text in more than 20 languages. Built on the Polaris constellation architecture, in which specialist support agents for privacy, checklists, and medication safety back the primary conversation agent and can end a non compliant conversation. Agents are barred from diagnosis and prescribing, escalate to humans when clinical judgment is required, and pass a certification pipeline that includes simulated call testing by thousands of nurses and physicians. More than 300 prebuilt agents across 25 specialties; the company reports over 115 million clinical patient interactions and 50 plus health system, payer, and pharma partners.

Specialty specific AI voice agents for the patient journey: scheduling, intake, triage and routing, referrals, medication refills, document processing, and payments, writing directly to the EHR in real time across more than 20 systems including native Epic and athenahealth integration. The platform is marketed as Assort OS, built on the Synapse proprietary model and trained on a reported 62,000 care protocols and 1.6 million decision pathways across more than 22 specialties. Patient interaction volume is vendor reported and varies across the company's own materials, cited as 180 million on its Crunchbase profile and 190 million elsewhere; trade coverage in October 2025 cited 42 million, so the figure is growing and should be read as directional. Agents include configurable stop logic that triggers a warm handoff when identity cannot be confirmed, required details are missing, or a patient signals clinical urgency.
