Flywire
Public payments company with a healthcare affordability arm
- Founded
- 2009
- HQ
- Boston, MA
- Stage
- Public (NASDAQ: FLYW)
- Raised
- $263M pre-IPO
What it does
- Digital patient billing and payment portal
- Analytics-driven patient outreach and engagement
- Self-service payment plans, provider-funded or financed
- Integrated non-recourse financing up to 60 months
- Cross-border payments in 140+ currencies
Where it's strong
- Public-company scale and financial transparency, with proven deployments at very large systems like Banner Health and CommonSpirit.
- The affordability suite lets providers offer long payment plans without carrying receivables, since financed plans are funded non-recourse.
- A Forrester Total Economic Impact study commissioned by Flywire found clients can reach a 269% ROI.
What buyers should weigh
- Healthcare is one of four verticals alongside education, travel, and B2B, and recent capital went to travel (the $330M Sertifi deal), so healthcare is not the company's center of gravity.
- It covers patient payments and engagement, not claims, denials, or payer-side revenue cycle work, so you still need other RCM tooling.
- Best suited to large systems with high patient-pay volume; smaller groups may not justify the platform.

Inbox Health
Patient billing communication for billing teams
- Founded
- 2014
- HQ
- New Haven, CT
- Stage
- Series B+
- Raised
- $60M+
What it does
- Patient billing platform built for medical billing companies
- Automated statement cycles across email, text, mail, and phone
- Built-in patient support that resolves most billing questions
- Online payments and payment plans
- Syncs balances with practice management systems
Where it's strong
- The only platform in this set designed around third-party billing companies, which serve thousands of small practices the enterprise vendors ignore.
- 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.
