What Inbox Health does

Inbox Health, Corp. is a New Haven, Connecticut-based healthcare technology company that has operated since 2014 as a patient billing and communications platform serving U.S. healthcare practices, specialty clinics, and third-party medical billing companies. The company's core product is an AI-automated billing workflow platform that handles the full patient accounts receivable cycle — from statement generation and multi-channel communication (email, text, phone/IVR, live chat, paper mail) through payment processing (credit card, ACH, digital wallet, phone, check) and patient support. The platform integrates with practice management systems to centralize patient A/R management and offers white-label customization for billing-company partners.

The technology stack includes an AI Support Assistant that resolves 90% of patient billing inquiries at first touchpoint without staff intervention, automated billing cycles that adapt follow-up messages based on individual patient interaction history, and HIPAA/SOC 2 Type II/PCI DSS/NIST 800-53 compliant infrastructure. Reported customer outcomes include 85% of patient A/R collected within 15 days and a 2x increase in total patient collections. The company operates a hybrid GTM combining direct enterprise sales, a partner program for white-label distribution, and a self-serve patient payment portal, with named customers spanning medical billing management firms (Keystone Medical Management, Precise Practice Management, The Auctus Group, PractiSynergy) and enterprise specialty practices (Eyecare Services Partners).

Inbox Health generates revenue via SaaS subscription to its patient billing platform, with pricing not publicly disclosed. The company is venture-backed, having raised approximately $55 million across multiple rounds, including a $22.5 million Series B in May 2023 and a $20 million growth equity round in September 2025 led by Ten Coves Capital. Recent strategic moves include partnerships with Encoda (December 2025) to integrate payer-side revenue cycle workflows and with AdvancedCare Partners (November 2025) to deploy AI billing automation across behavioral health and psychiatry provider networks.
