Infinx
AI plus specialists for prior auth and patient access
- Founded
- 2012
- HQ
- San Jose, CA
- Stage
- Growth (KKR minority stake 2024)
- Raised
- $186M reported
What it does
- AI prior authorization determination, submission, and status tracking
- Eligibility verification and benefits checks in one platform
- Patient pay estimates before service
- Certified specialists work exceptions automation cannot resolve
- AR recovery and denial management services
Where it's strong

- Deep roots in high-volume prior auth specialties like radiology, labs, and cardiology.
- Trusted by more than 900 provider organizations, with KKR and Norwest backing.
What buyers should weigh
- Part of the value is outsourced labor, so compare its per-transaction economics against pure software options.
- Named customer references are rare in public materials; case studies are anonymized.
- Broad service catalog means implementation scope needs careful definition up front.
Integrations
Silna Health
Prior auth and benefits automation for therapy providers
- Founded

Where it's strong
- Purpose-built for therapy and specialty providers like ABA, where prior auth volume is the core operational pain.

What buyers should weigh
- Young company (founded 2023) with a short track record and no large publicly named customers.
- Narrow front-end focus: it handles benefits and auth, not claims, denials, or the rest of the revenue cycle.
- The no-integration approach means data lives in a separate staff-facing tool rather than flowing into your EHR automatically.
