SuperDial

Overview

SuperDial is a San Francisco-based voice AI company that automates outbound phone calls from healthcare providers and billing companies to insurance payers. Its AI agents navigate payer IVR phone trees, wait on hold, conduct live conversations with payer representatives, and write results back into the customer’s EHR or RCM system — end to end, without human intervention unless escalation is required.

The core thesis: U.S. healthcare spends over $150 billion annually on revenue cycle operations, with a massive share driven by repetitive phone-based administrative tasks. SuperDial proposes to eliminate these calls as a human burden.

Founding History: Sam Schwager (Stanford CS/AI; former McKinsey) and Harrison Caruthers (Stanford Symbolic Systems/AI; former Amazon SWE) incorporated as Haven Health, Inc. in June 2021, initially building a remote group therapy platform. They pivoted to SuperBill (patient-facing out-of-network claims filing fintech) in late 2021. The insight that drove SuperDial’s creation came from operating SuperBill: the team was spending thousands of hours manually calling payers. They built an internal automation tool, recognized its commercial potential, and by late 2023 spun it out as SuperDial.

Services & Capabilities

Core Product: Voice AI Agents for RCM

SuperDial’s AI agents handle five primary RCM workflow categories:

1. Prior Authorization — Retrieve PA requirements and status; navigate decision trees; initiate requests; track through determination; escalate denials with appeal information
2. Benefits Verification (Eligibility) — Confirm deductible, co-pay, co-insurance, and coverage details pre-appointment
3. Claims Follow-Up — Follow up on denied, delayed, or unpaid claims; resolve automatically
4. Credentialing & Enrollment — Inquire about enrollment/credentialing status for providers
5. Provider Data Attestation — Confirm clinician status, credentials, new patient acceptance

Additionally supports custom outbound scripts — fully customizable call flows — a notable differentiator from more rigidly templated competitors.

Technical Architecture

• IVR/Phone Tree Navigation: Proprietary logic augmented by January 2025 MajorBoost acquisition (Allen Institute for AI spinout) to map and traverse payer-specific phone menus
• Conversational AI: LLM-powered dialogue for multi-turn conversations, push-back handling, and unstructured data extraction
• Context Injection: Patient/claim data from EHR/RCM system embedded into agent context at call time
• Human-in-the-Loop (HITL) Fallback: When AI cannot complete a call, human call center team steps in — critically generating labeled training data to improve models
• Bidirectional EHR Integration: Epic, Cerner, eClinicalWorks, athenahealth, AdvancedMD via HL7/FHIR APIs. Named health system partners include Cincinnati Children’s and Mount Sinai
• Flywheel Data Advantage: Proprietary data flywheel using HIPAA-compliant, de-identified outcomes from prior transactions to improve future AI performance

Reported Performance

Metric	Reported Value
Cost savings per call	Up to 3x vs. manual
Productivity increase	Up to 4x for billing teams
First-pass PA automation	99% (self-reported)
Call automation success	>90%
Per-call cost reduction	25-50%

Named customer case studies: West Coast Dental (70,000-claim backlog cleared; 10,000+ calls/month), Apex IONM ($12M+ in billed claims automated), United Medical Monitoring (5,400+ staff hours saved in one quarter), NMA (4x follow-up capacity increase).

Competitive Position

Direct Competitor: Infinitus Systems

Dimension	SuperDial	Infinitus Systems
Founded	2021 (product: 2023)	2019
Total Funding	~$20M	~$102.9M
Primary Customer	RCM companies, DSOs, MSOs, provider groups	Pharma patient support, specialty pharmacy, large health systems
Human-in-loop	Human call center for unresolved calls	FastTrack copilot (human drops in after IVR bypass)
Scale	Millions of calls (trending 10M/yr by end 2025)	6M+ calls, 100M+ minutes
Enterprise footprint	Emerging	44% of Fortune 50 healthcare companies

Key strategic differences: (1) Market segment — Infinitus built around pharma patient support programs (higher-acuity, higher-margin); SuperDial targets provider-side RCM (higher-volume, lower-complexity). (2) Customizability — SuperDial emphasizes configurable scripting; Infinitus uses standardized therapy-specific knowledge graph flows. (3) Capital gap — Infinitus has ~5x capital, a16z board, Fortune 50 relationships. (4) AI guardrails — Infinitus publishes detailed hallucination-prevention architecture; SuperDial addresses risk via HITL and context injection.

Broader Landscape

Also competes with Outbound AI (horizontal RCM voice AI), Amperos and Opkit (smaller payer-facing AI), and faces long-term structural threat from electronic PA incumbents (CoverMyMeds, Surescripts, Waystar) as FHIR-based APIs mandated by CMS 2027 become available. SuperDial’s counterpositioning: many payers have actually increased reliance on phone/fax for complex PAs even as electronic options expanded.

Recent Developments

January 2025 — MajorBoost Acquisition. Acquired MajorBoost, a Seattle-based AI startup spun out of AI2 Incubator in 2020. Deepened IVR navigation capabilities. MajorBoost CEO Lekshmi Venu joined SuperDial. Clients had reported up to 45% improvement in tasks completed per day.

June 2025 — $15M Series A. Led by SignalFire (first investment from their new $1B applied AI fund). Tom Peterson (ex-Evolent Health COO) joined as strategic advisor via SignalFire’s XIR program. $3M venture debt included.

November 2025 — SOC 2 Type II Certification.

December 2025 — athenahealth Marketplace. Enabling athena customers to discover and deploy SuperDial within their EHR environment.

March 2026 — Omega Healthcare Partnership. SuperDial’s voice AI agents embedded into Omega Healthcare’s (Best in KLAS 2026 for Ambulatory RCM) agentic AI platform. First major RCM outsourcer to embed third-party voice AI natively. B2B2B channel for capital-efficient customer acquisition.

CMS 2026 Prior Authorization Rule as Tailwind. CMS-0057-F mandates 7-day standard PA determinations and 72-hour urgent PAs, with FHIR-based API infrastructure by 2027. Creates compliance urgency for providers to automate PA workflows.

Financial Profile

Metric	Value
Total funding	$20M+
Latest round	Series A, $15M (June 2025, led by SignalFire)
Revenue	Seven-figure ARR (confirmed June 2025)
Employees	~45
Revenue stage	Early revenue, scaling
Pricing model	Usage-based (per completed call)
Key investors	SignalFire, Slow Ventures, BoxGroup, Scrub Capital

Pre-profitability. The $3M venture debt tranche suggests equity sized for GTM and R&D headcount. Disclosed use of funds: AI engineering hires, sales/marketing buildout, deeper EHR integrations.
