SuperDial secures USD $15M to expand healthcare voice AI

SuperDial has secured USD $15 million in series A funding to expand its voice AI platform that automates healthcare administrative phone calls in the United States.

The new financing round, combining debt and equity, was led by SignalFire, with Slow Ventures, BoxGroup, and Scrub Capital also participating. The round includes USD $3 million in venture debt to support SuperDial's research and development and commercialisation strategies, bringing total funds raised by the company to over USD $20 million.

SuperDial's technology is designed to help billing and provider organisations in the healthcare sector reclaim time and revenue by replacing lengthy insurer calls with end-to-end AI agents. Administrative phone calls are widely recognised as a significant expense in US healthcare, contributing billions of dollars each year to operational costs for provider organisations and billing companies.

The voice AI platform manages outbound phone calls from providers and billing companies to insurers. It is capable of navigating phone menus, holding for a representative, and conversing with payer representatives. The agents handle routine but high-friction administrative tasks including benefits verification, prior authorisation, claims follow-up, and credentialing. SuperDial also employs a human call centre team to intervene when a call cannot be completed by an AI, which supports reliability and the ongoing improvement of the AI agents.

Platform and integration

SuperDial's solution integrates with electronic health records (EHR) and other record-keeping systems, enabling it to automate documentation. This integration includes recording data gathered from calls, such as claims status updates, which customers use to cut costs and create efficiencies across revenue operations teams.

According to customer accounts, organisations have reported up to threefold cost savings per call and four times productivity improvements in their billing teams. The company was established by Sam Schwager and Harrison Caruthers, both of whom have extensive experience in healthcare administration and computer science.

Reflecting on the creation and growth of the company, Sam Schwager, Co-Founder and Chief Executive Officer of SuperDial, said:

"The timing is perfect for us to tackle this problem at scale, with AI capabilities quickly maturing and the healthcare sector looking for new ways to drive efficiency by leveraging next-gen technology. Our success to date, and the incredible level of interest and excitement we're seeing from the market, are clear signs that we're solving a real, urgent problem."

Since launching at the end of 2023, SuperDial has reported achieving seven figures in revenue and processing tens of thousands of calls each week. In early 2025, the company acquired MajorBoost, a voice AI organisation with a focus on insurer phone navigation and workflow, strengthening SuperDial's technical expertise and specialisation in healthcare phone call automation.

Customer adoption

The expansion of SuperDial comes as healthcare providers look to decrease administrative costs without increasing staff numbers. Administrative phone calls are a persistent manual process in the USD $150 billion revenue cycle management (RCM) sector, often taking over an hour for basic tasks and pulling staff away from other responsibilities.

SuperDial's clients include RCM companies and large healthcare provider groups. One example is West Coast Dental, which relies on SuperDial to manage over 10,000 calls per month for claims status checks. Previously, the process left almost 70,000 claims in backlog and would have required hiring five additional staff members. After implementing SuperDial's platform, the company reduced accounts receivable days and improved real-time claims visibility.

Yuanling Yuan, Partner at SignalFire, commented on the investment and the company's direction:

"SuperDial isn't just automating phone calls – they're building the connective tissue for how the healthcare ecosystem will communicate in the future. We believe agentic AI infrastructure is inevitable, and SuperDial is leading that shift with rapidly growing traction and a team that deeply understands the problem. This is exactly the kind of applied AI we're excited to back."

SuperDial plans to continue strengthening its EHR integrations, expand its automation to new administrative workflows, and promote further development using real-world call data. The company suggests that while healthcare organisations have not developed APIs to support system-to-system communication, its network of AI agents serves as an alternative infrastructure, helping organisations bridge gaps in fragmented systems.

SuperDial anticipates that, in future, healthcare coordination will increasingly become reliant on agent-powered communication, with AI agents facilitating seamless information exchange among payers, providers, pharmacies, laboratories, and other related healthcare entities.
