AI voice automation platform handling healthcare phone calls — benefits verification, prior auth, and referrals — at scale. San Francisco CA; raised $52M+ (a16z, GV);
About
Infinitus Systems is a healthcare AI company that automates the high-volume, repetitive phone call work that burdens provider administrative teams. Founded in 2019 and headquartered in San Francisco, California, Infinitus has raised more than $52 million from investors including Andreessen Horowitz and GV. The company's AI voice agent, called Maya, conducts real-time phone conversations with insurance payers to verify benefits, check prior authorization status, confirm referrals, and gather other eligibility information on behalf of healthcare providers.\n\nTraditionally, benefits verification and prior authorization follow-up requires large teams of staff members spending hours on hold and navigating complex phone trees. Infinitus replaces this manual process with an AI agent that operates around the clock, completing calls faster than human agents and capturing structured data directly into provider workflows. Customers include health systems, specialty practices, revenue cycle management outsourcers, and digital health companies that need to scale patient access operations without proportionally growing headcount.\n\nThe platform is designed for interoperability, delivering results through APIs and direct integrations with EHR systems, practice management software, and RCM platforms. Infinitus has processed tens of millions of healthcare transactions and continues to expand the scope of calls its AI can handle, with a roadmap that includes scheduling, referral coordination, and patient-facing outreach.
London and New York AI platform automating insurance prior authorization; reads patient clinical records to extract evidence justifying medical necessity and cut treatment delays.
About
Anterior is a London and New York-based healthtech company that applies AI to automate the prior authorization process, one of the most burdensome administrative tasks in U.S. healthcare. Prior authorization requires physicians to submit clinical evidence to insurance companies justifying the medical necessity of treatments, procedures, or medications — a process that consumes significant physician and staff time and causes treatment delays that harm patient outcomes. Anterior's AI reads patient clinical records, identifies the relevant clinical criteria required by the insurer, extracts supporting evidence from the patient's history, and generates complete prior auth submissions automatically. The platform also predicts approval likelihood and flags cases likely to require clinical review, helping health system staff prioritize their work. Founded in 2022, Anterior raised funding from investors including Sequoia Capital and has rapidly signed health system customers facing acute prior authorization burdens. The company's approach addresses a systemically inefficient process that costs the U.S. healthcare system an estimated $35B annually in administrative waste.
