Where it's strong

PayZen
Affordability platform with pay-over-time for care
- Founded
- 2019
- HQ
- San Francisco, CA
- Stage
- Series B
- Raised
- $230M+ incl. debt facilities
What it does
- AI underwrites every patient for an affordable plan
- Zero-interest, no-fee installment plans for patients
- Pays providers upfront and takes on repayment risk
- Care Now, Pay Later financing before treatment
- Embedded in Epic and other EHR billing workflows
Where it's strong
- Converts aging self-pay balances into upfront cash for the health system while patients get zero-interest plans, a genuinely different model from statement optimization vendors.
- Approves every patient regardless of credit, which protects the patient experience and avoids the reputational problems of medical credit cards.
- Serious capital behind it: an NEA-led Series B with $200M in credit warehouse capacity, plus about 60 health system and physician group clients including Geisinger and CommonSpirit.
What buyers should weigh
- The provider pays for the upfront cash through program economics, so model the effective discount against your current self-pay recovery rate.
- It addresses affordability and financing, not the whole billing experience; many systems pair it with a broader engagement platform.
- Patient financing is credit-adjacent and drawing regulatory attention, so review compliance, disclosures, and collection practices carefully.
