Bottom line
- Pick Anterior if you are a health plan that wants clinician-supervised AI to cut prior auth review time while keeping final decisions with your own staff.
- 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.
Anterior
Clinician-led AI for health plan clinical reviews
- Founded
- 2023
- HQ
- New York, NY
- Stage
- Series B
- Raised
- $64M
What it does
- AI clinical reasoning against payer medical policies
- Prior authorization review with nurse-in-the-loop workflow
- Auto-approval of clean requests, flagging of edge cases
- Embedded clinicians who tune accuracy in production
- Audit trails for every determination
- Five-day average deployment into plan workflows
Where it's strong
- Clinical accuracy of 99.24% in live production was independently validated by KLAS Research.
- Founded and staffed by clinicians, which helps with medical director buy-in inside plans.
- Deploys into existing UM workflows in days rather than the multi-month integrations typical of payer software.
What buyers should weigh
- Sells only to payers, so provider organizations looking for a submission-side tool are not the buyer.
- Young company with a small number of named reference customers, so diligence on scale is warranted.
- State laws increasingly require licensed clinicians to make denial decisions, so buyers must define where AI output stops and human judgment starts.

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.
