Company profile
researched Sep 2026Artera provides an AI-powered patient communication platform for healthcare provider organizations, delivering voice and text agents that handle administrative and clinical front- and back-office workflows. Its Harmony platform coordinates agentic AI across the patient journey — communications, scheduling and rescheduling, intake, payments, pre-appointment cancellation and verification, prescription refills and renewals, post-appointment and discharge follow-up, triage, FAQs and care gaps — while routing exceptions to human staff, who retain full conversation history and control. Artera pairs the platform with "AI Service Squads," internal teams that build customized agentic solutions for a customer's specific workflows rather than selling off-the-shelf software alone.
The company serves specialty groups, clinics, federally qualified health centers (FQHCs), large integrated delivery networks, health systems and federal agencies, with specialty-specific solutions spanning areas such as behavioral health, cardiology, dermatology, gastroenterology, oncology, orthopedics, pediatrics, primary care and women's health. Artera integrates with major EHRs and states it supports communications in 109 languages across voice, text and web. Security and compliance positioning includes SOC 2 Type 2, HITRUST certification, ISO and HIPAA compliance, more than seven security certifications, FedRAMP High "in process" status, and a policy of not using PHI/PII to train models.
Founding story
Artera was founded in 2015 following a personal health scare experienced by its founder, which highlighted how inconvenient and inefficient coordinating care is for patients. At the time, much of patient–provider communication still relied on holding on the phone, voicemails and missed calls, and freeform texting was not yet legally permissible for healthcare purposes (which subsequently changed). The founders concluded that the communication burden rested disproportionately on patients and set a mission of making healthcare the number one industry in customer service.
Business model
Artera sells a subscription software platform to healthcare provider organizations, measured internally in Contracted Annual Recurring Revenue, and combines it with dedicated services teams ("AI Service Squads") that build and maintain custom agentic solutions. It also acts as the white-labeled communications layer for major EHR vendors and exposes APIs used by third-party digital health vendors.
Recurring contracted revenue from provider organizations for platform access and custom AI agent solutions; the company reported $100 million in Contracted Annual Recurring Revenue by the end of 2025.
Traction
Artera reports more than 1,000 healthcare provider organization customers, over 2 billion patient-to-provider communications supported annually, 20B+ cumulative patient interactions, engagement with 100 million patients annually (with over 200 million patients engaged through its AI solutions), 109 supported languages, 50+ marketplace vendor partners generating 200+ million annual API calls, and $100 million in Contracted Annual Recurring Revenue at the end of 2025. Website figures include 65% AI agent task completion.
Latest developments
On December 3, 2025, Artera announced a $65 million growth investment led by Lead Edge Capital with participation from existing investors Jackson Square Ventures, Health Velocity Capital, Heritage Medical Systems and Summation Health Ventures, alongside reaching $100 million in Contracted Annual Recurring Revenue. The funding is earmarked for growth and expanded adoption of agentic AI in healthcare.
▸Full profile — market position, technology, go-to-market, geography, history
Market position
Positioned as an established digital patient communications vendor with a decade of operating history, contrasting itself with generic SaaS, single-point solutions and consultancies, and with newer AI entrants that lack healthcare distribution, EHR relationships and historical operational data. The company cites a #1 ranking in KLAS for patient communications and 50+ awards and recognitions.
The company frames its moat as three combined assets: healthcare infrastructure and platform breadth; a proprietary knowledge base accumulated over ten years covering more than two billion annual patient-provider interactions and 200 million unique patients; and established distribution via 1,000+ provider customers, EHR integrations and federal relationships. It also differentiates on delivering services teams alongside software rather than software alone.
Technology
Agentic AI voice and text agents built on the Artera Harmony platform, supporting scheduling, intake, payments, refills, triage and follow-up, with warm handoff to human staff and complete conversation logging. The company adopts standards such as Model Context Protocol (MCP), integrates with major EHRs, and cites a proprietary dataset of over two billion annual patient–provider interactions spanning more than 200 million unique patients as training and monitoring input. Security posture includes SOC 2 Type 2, HITRUST, ISO and HIPAA compliance and FedRAMP High "in process" status covering more than 600 security controls.
Go-to-market
Direct sales to provider organizations combined with distribution through EHR partnerships — Artera is the white-labeled communications solution behind Oracle Health's Unified Consumer Communications and MEDITECH's Expanse Patient Connect — plus a marketplace of 50+ digital health vendor partners using Artera APIs (over 200 million annual API calls). The company also runs a customer conference, Heartbeat, and maintains a dedicated federal business unit (Artera Government Solutions).
Healthcare provider organizations in the United States, including specialty groups and practices, clinics, FQHCs, large integrated delivery networks and health systems, and federal agencies such as the Department of Veterans Affairs, Department of Defense and Indian Health Service sites.
Geography
Headquartered in Santa Barbara, California, with customers across the United States, including federal government health sectors.
History
Founded in 2015, the company spent roughly a decade building digital patient communication products before shifting toward agentic AI. It unveiled virtual agent solutions at its customer conference, Heartbeat'24, in September 2024, after which hundreds of healthcare providers deployed Artera Agents, including AI Agents, Flows Agents and Co-Pilots. In December 2025, Artera announced a $65 million growth investment alongside reaching $100 million in Contracted Annual Recurring Revenue by the end of 2025.
