The problem

Primary care clinics lose 38% of appointments and 4 admin-hours a day trying to fix it.

Independent clinics — the 22,000 that don't belong to a hospital system — carry this loss alone. There's no tool built for them. Most use a part-time admin and a phone.

The solution

Sundial is the AI layer that calls patients back, fills cancellations, and learns each clinic's population.

  • Voice-AI confirmations and re-scheduling. Sundial calls every appointment 24 hours ahead — actual conversational AI, not robocalls. 78% of patients pick up; 64% confirm or rebook in under 90 seconds.
  • Real-time cancellation backfill. When a slot opens, Sundial calls the right patient from the waitlist — selected by clinical priority, not by who asked first. Average fill time: 11 minutes.
  • Population learning. The model learns each clinic's no-show patterns by patient cohort, time of day, weather, season. A clinic in El Paso gets a different model than one in Portland — automatically.
  • Sits on top of every EHR. Reads from Epic, Cerner, athenahealth, and DrChrono via standard APIs. No clinical workflow changes; admin sees Sundial as a feed of confirmed appointments.

Why now

Three forces have converged that didn't exist 24 months ago.

— 01 Capability

Voice AI crossed the believability line in late 2024.

The combination of low-latency speech models, retrieval-augmented dialogue, and natural turn-taking made AI phone calls indistinguishable from human ones for routine scheduling. Two years ago this was a research demo; today it's a product layer.

— 02 Pain

Care-staff shortage has become structural, not cyclical.

Healthcare admin labor is 17% short and projected to widen through 2028. The 22K independent clinics can't compete with hospital systems on wages. Every clinic we've talked to has tried — and failed — to hire admin help.

— 03 Buyer readiness

Telehealth normalized the "scheduling layer" as a buying category.

Before 2020, primary-care clinics didn't buy software outside their EHR. The telehealth wave taught them that scheduling and EHR are separable. We're entering a market that now has a checking account for our category.

This is signal, not traction. Two paying pilots aren't a business. They are evidence the wedge works in production — and a credible launch point for the build that the seed funds.

Where this goes

The operating layer for the 22,000 clinics that don't have one.

Scheduling is the wedge. The same voice-AI infrastructure that handles confirmations will, in time, handle intake forms, billing follow-up, and care-gap outreach. We start where the pain is sharpest.
