Super Dial raises $15M Series A to automate healthcare revenue cycle management calls with voice AI
Jun 24, 2025 with Sam Schwager
Key Points
- Super Dial closes $15M Series A led by SignalFire to scale voice AI that automates outbound calls from healthcare billing teams to insurers for claim status and prior authorization checks.
- The company pivoted from Super Bill, an RCM vendor, 18 months ago after building voice automation internally; its moat lies in RCM domain knowledge and insurer phone tree navigation, not the underlying AI models.
- Outbound payer calls represent a billions-dollar annual workflow with far fewer competitors than appointment scheduling or customer support, making it a high-volume, repetitive niche well suited to automation.
Summary
Super Dial has closed a $15 million Series A led by Signal Fire, announced June 24, 2025 by co-founder and CEO Sam Schwagger. The company automates outbound phone calls in healthcare revenue cycle management, specifically the high-volume calls that billing teams and RCM companies make into health insurers to check claim status, verify benefits, and handle prior authorizations.
The business is a pivot. Super Dial began as an RCM company called Super Bill, built voice automation internally to handle its own call volume, then spun that capability into a standalone product and converted the entire company roughly 18 months ago. That operational history in billing is central to its positioning: the product requires deep RCM domain knowledge baked into system prompts and dynamic call-time context, or the AI agent loses the thread mid-call.
The competitive landscape is narrower than it appears. While voice AI for appointment scheduling or customer support has attracted a crowded field, the specific niche of outbound payer calls from RCM teams has far fewer direct competitors. Schwagger estimates the total call volume in this category runs into the billions annually, making it a high-volume, high-repetition workflow well suited to automation.
On the technical stack, Super Dial works with third-party partners for text-to-speech, speech-to-text, and LLM capabilities, uses cloud compute, and handles phone call orchestration through open-source tooling rather than a full-service voice agent platform. The moat, per Schwagger, sits at the workflow and integration layer, navigating insurer phone trees, knowing which numbers to call, and injecting the right RCM context at call time. Schwagger made the announcement from the Healthcare Financial Management Association annual conference, signaling an active enterprise sales motion targeting the RCM industry directly.
