Bottom line

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.
