SignalFire backs SuperDial to tackle healthcare’s $1T admin bottleneck

‎Ask any healthcare professional what’s broken in the system, and the answer isn’t always clinical—it’s the operational burden. Nearly 25% of U.S. healthcare spending goes to administrative busywork, not care delivery. That’s over $1 trillion per year lost to paperwork, phone calls, and data entry tasks. 

From verifying insurance coverage to chasing down claim denials, providers and revenue cycle teams spend millions of hours on repetitive, low-value calls. Burnout is high, staffing is tight, and the patient experience suffers. These tasks are not only costly and inefficient, they also pull skilled clinical and operational talent away from high-impact work.

It’s a broken system hiding in plain sight, and one we believe is ready for transformation. That’s why SignalFire is proud to lead SuperDial’s $15M Series A to automate the biggest, most invisible cost in U.S. healthcare.

SuperDial’s vertical AI strategy is the right approach to tackle healthcare’s admin bloat. Their ability to integrate with enterprise workflows and deliver 4X throughput is exactly what this industry needs right now.

Cracking the code of healthcare’s admin overload crisis

Built specifically for the complex world of healthcare operations, SuperDial automates the tedious call workflows between providers, payors, and revenue cycle management (RCM) teams. Their voice agents can resolve insurance claims, verify coverage, and route calls to human staff only when necessary, freeing up teams to focus on their patients.

SuperDial’s AI agents are trained on the exact language and logic of payor phone trees, letting provider and RCM teams operate with unprecedented efficiency.

• Navigating payor phone trees
• Verifying patient benefits
• Handling prior authorizations
• Following up on claims and credentialing

Their AI agents also escalate calls to human staff when needed.

With its vertical AI strategy built specifically for healthcare operations, SuperDial is having a real-world impact: One customer used SuperDial to resolve a 70,000-claim backlog and now automates over 10,000 calls per month. Another saw a 4X increase in claim throughput without hiring a single additional employee.

In an industry where phone-based administrative work is a $100B+ cost center, these are more than incremental improvements; they’re systemic efficiencies.

Built by founders who felt the pain

Co-founders and Stanford alumni Sam Schwager (ex-McKinsey) and Harrison Caruthers (ex-Amazon) didn’t set out to build a voice AI platform. Their first iteration of the business was to help providers streamline billing workflows. After watching their clients burn countless hours on phone-based admin work, they recognized the root of the inefficiency and shifted their focus.

That insight and urgency to build for a need they experienced firsthand is exactly what we look for in founders. Sam and Harrison are the kind of technical, high-velocity founders we’re drawn to: Stanford-trained in AI, moving with clarity, urgency, and precision as they scale their team.

A strategic partnership through SignalFire's XIR program

SignalFire’s investment in SuperDial is strengthened by our unique Executive-in-Residence (XIR) program that’s designed to pair generation-defining startups with world-class industry leaders. To invest in a company tackling healthcare’s $1T admin burden, we partnered with Tom Peterson, former co-founder and COO of Evolent Health (NYSE: EVH). Tom brings over 20 years of healthcare leadership and operational experience, and will be actively supporting SuperDial’s go-to-market and strategic growth.

SuperDial's deep RCM expertise, vertical focus, sophisticated voice AI technology, scalability, and the configurability of their prompts put them head and shoulders above the competition. Their focus on revenue cycle on the provider side, and claims and provider data management on the payor side, enables them to build deep IP and differentiation that is unparalleled in the market.

A full-stack OS for healthcare’s back office workflows

SuperDial isn’t just augmenting admin staff, it’s a full-stack operating system for automating the repetitive, high-stakes phone-based workflows at the heart of healthcare. Their acquisition of MajorBoost earlier this year brought deep integrations with payor systems and expanded capabilities, especially in automating IVR navigation and post-call data processing, critical for scaling AI-driven admin infrastructure. 

Their forward-deployed engineering model ensures seamless fit with enterprise IT platforms and tools, and by focusing on collaboration, not replacement. They’ve become the AI teammate human teams actually want to work with by offering:

• Proprietary call handling and escalation logic
• A growing library of payor-specific phone tree maps
• Seamless integrations with EHR and billing systems
• Human fallback that doubles as training data

Unlike many AI tools built for generic use cases, SuperDial’s advantage lies in its domain depth. It knows the language, logic, and legacy systems of healthcare. And because payors largely follow standardized processes, the system gets better and more defensible with every new customer and call.

At SignalFire, we back founders tackling massive markets with deeply technical, domain-specific solutions. SuperDial fits that description perfectly. They’re engineering ROI for one of the most regulated, costly, and complex industries in the world. We’re excited to support them as they become the standard for healthcare voice automation. 

Over time, we believe SuperDial will evolve from call automation to the clearinghouse infrastructure layer for provider-payor coordination by not just automating calls, but creating a real-time feedback loop of healthcare admin intelligence, and this moat will only get stronger with scale.

A natural fit for SignalFire’s Vertical AI focus

At SignalFire, we believe the next generation of breakout companies will be AI-native, vertically focused, and infrastructure-oriented. From automating complex payor interactions to enabling new workflows for TPAs, MSOs, and large RCM vendors, SuperDial is positioned to capture enormous value in one of the most complex and underserved sectors in healthcare.
