Bottom line
- Pick Rhyme if you are a large health system or health plan that wants prior auth handled inside the EHR through a shared payer-provider network.
- Pick Silna if you run a therapy or specialty practice (ABA, PT/OT, behavioral) and want benefit checks and prior auths done for you within weeks of signing.
Rhyme
Connecting payers and providers for touchless auths
- Founded
- 2014
- HQ
- Columbus, OH
- Stage
- Venture-backed (Series B era)
- Raised
- $57M
What it does
- Submits and tracks prior auths inside provider EHR workflows
- Connects providers and payers on one shared auth network
- Touchless auth processing with real-time payer decisions
- Gold carding programs that waive auths for trusted providers
- Shared payer-provider dashboard for auth status and collaboration
Where it's strong
- A working two-sided network: 80 to 90 of the largest health systems and over 300 payers processing 4 to 5 million auths a year.
- Auths run inside the EHR workflow staff already use, so adoption requires little retraining.
- Its gold carding model removes prior auth entirely for high-performing providers rather than just speeding up submissions.
What buyers should weigh
- Rhyme is connectivity and workflow, not a clinical decision engine; payers still need their own UM review stack (its Medical Mutual deal paired it with Cohere for exactly that reason).
- Value depends on payer overlap; auths for payers outside the network fall back to portals, fax, and phone.
- At roughly $57M raised and a modest team, it is a smaller vendor than RCM incumbents like Availity or Waystar, so weigh long-term durability and roadmap capacity.

Silna Health
Prior auth and benefits automation for therapy providers
- Founded
- 2023
- HQ
- New York, NY
- Stage
- Series A
- Raised
- $27M
What it does
- Automates benefit checks and eligibility verification before visits
- Prepares, submits, and tracks prior authorization requests
- Monitors authorizations and flags expirations and renewals
- Covers 1,000+ payers across all 50 states
- Sits alongside existing EHR and practice management systems
- Built for ABA, PT/OT, speech, psychiatry, and other therapy specialties
Where it's strong
- Purpose-built for therapy and specialty providers like ABA, where prior auth volume is the core operational pain.
- Fast deployment because it sits alongside your stack rather than requiring deep EHR integration.
- Strong reported results: insurance verification cut from 30 minutes to 30 seconds and approvals in hours with a claimed 99.8% success rate.
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.
