Bottom line

Cedar
Consumer-grade patient billing for health systems
- Founded
- 2016
- HQ
- New York, NY
- Stage
- Series D
- Raised

What it does
- Consolidated digital patient billing and payment experience
- Personalized outreach and payment options driven by ML
- Kora AI voice agent answers inbound billing calls
- Bill explanations and coverage context inside the bill
- Delivers billing inside Epic MyChart
Where it's strong
- The category leader for patient financial experience at large health systems, with reference customers like Novant and Yale New Haven and 300,000+ patient interactions a day.
- Deep Epic and MyChart integration means the experience shows up where patients already are, not in yet another portal.
- Its 2025 agentic AI line (Kora, Bill Navigator, Agent Copilot) attacks call center cost, projecting 30% of inbound billing calls automated.
What buyers should weigh
- Built for large health systems and physician enterprises; small and mid-size groups are not the target and should look at Collectly or similar.
- Commercial terms typically scale with patient payment volume, so model the effective take rate against your current cost to collect.
- It improves the patient-facing layer but is not a full RCM replacement; your billing stack stays.

- Patient billing platform built for medical billing companies

Where it's strong

- Proven distribution: 2,600+ practices reached through billing company partners and 3.5M+ patients have paid a bill on it.
- Its patient support layer answers billing questions itself, reported at 90% resolution, which directly cuts billing company phone load.
What buyers should weigh
- If you are a practice rather than a billing company, you will usually access it through a partner, which adds a layer to the relationship.
- Its September 2025 $20M raise was structured as other equity rather than a priced Series C, worth understanding in diligence.
- Channel focus means the patient experience can vary with how well your billing company configures it.
