Cohere Health
Intelligent prior auth platform for payers
- Founded
- 2019
- HQ
- Boston, MA
- Stage
- Series C
- Raised
- $200M
What it does
- Automates prior auth intake, review, and approval for health plans
- Auto-approves up to 90 percent of eligible auth requests
- Applies evidence-based clinical policies and physician-facing nudges
- Provider performance analytics to steer utilization management
- Payment integrity claims validation via Cohere Validate
- Delegated UM services across MSK, cardiology, imaging, sleep
Where it's strong
- Proven at national scale: over 12 million prior auth requests a year across roughly 600,000 providers, including a nationwide Humana deployment.
- High auto-approval rates (up to 90 percent) materially cut turnaround times and provider abrasion, which matters as CMS-0057 deadlines arrive.
- Well capitalized at $200M raised and expanding beyond prior auth into payment integrity, reducing single-product risk.
What buyers should weigh
- It sells to health plans, not providers; a provider organization only encounters Cohere through a payer that has adopted it.
- Much of its track record is concentrated in the Humana relationship, so plans of smaller size should ask for comparable references.
- Delegated UM and clinical policy alignment make implementations substantial projects with real compliance and integration work, not a light SaaS install.

Integrations
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.
