SuperDial raises $15 million

SuperDial , a San Francisco-based startup specializing in AI-driven revenue cycle management, announced $15 million in new funding.

The debt and equity series A round was led by SignalFire, with participation from Slow Ventures, BoxGroup, and Scrub Capital. It includes $3 million in venture debt for SuperDial to invest in R&D and go-to-market initiatives. In total, the company has now raised over $20 million in funding. This also marks one of the first investments from SignalFire’s new $1 billion fund focused on applied AI.

Founded in 2021, SuperDial builds AI agents that handle outbound phone calls from providers and billing companies to insurers – navigating phone trees, waiting on hold, and conducting live conversations with payer reps. These AI agents support tasks like benefits verification, prior authorization, claims follow-up, and credentialing. When a call can’t be completed by an AI agent, SuperDial’s human call center team steps in, ensuring reliable outcomes while continually improving the AI.

“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.” – Sam Schwager, Co-Founder and CEO of SuperDial.

“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.” – Yuanling Yuan, Partner at SignalFire.

Earlier this year, SuperDial acquired MajorBoost , a voice AI company specialized in navigating complex phone trees and insurer workflows.
