Precision Healthcare AI
An AI intelligence platform for Claim Integrity.
Grelin is the AI intelligence platform that powers Claim Integrity across Healthcare workflows. We specialize in transforming complex auditing into a streamlined, automated process that ensures precision at every touchpoint.
Get every claim right. Before it is written, and after it is filed.
Providers carry the denial.
Billing teams spend weeks auditing, correcting, and resubmitting claims that could have been paid on day one if validated upstream.
Payers carry the appeal.
Administrative overhead compounds as multi-thousand page records are manually scanned, appealed, and reviewed through backlogs.
Patients carry the friction.
Delayed treatments, unexpected letters, and clinical confusion multiply. The clinical care bond is broken at the point of sale.
Section 3 · Why Grelin Exists
The revenue cycle worked backwards for decades.
Claims went out. Denials came back. Teams investigated, corrected, and resubmitted. The work was real. It just happened too late. Grelin moves the work upstream. Every claim, every specialty, validated before it reaches the payer.
Our Core Principles
What We Believe
Claim Integrity is upstream work.
The current healthcare infrastructure is built to react to errors after they occur. We believe the only way to solve the integrity crisis is to validate claims at the point of creation, before they ever enter the payment stream.
The stack you have is the stack you keep.
Healthcare doesn't need another disruptive platform that requires “ripping and replacing.” We believe AI should be an invisible layer that integrates seamlessly with existing EMRs and Billing systems, enhancing what works and fixing what doesn't.
Specialty knowledge is the moat.
Generic AI models cannot audit complex healthcare claims. We believe true Claim Integrity requires deep, specialty-specific medical intelligence that mirrors the expertise of the highest-performing human auditors.
One Platform. Specialty Applications on Top.
What the platform does
The Grelin Platform acts as the centralized brain. It ingests clinical data, maps it to complex regulatory rules, and provides the foundational API layer that powers every specialty audit. It is the engine of precision, designed for scale and clinical accuracy.
What the applications do
Our vertical applications, Wound.ai, Pain.ai, and EM.ai, are the expert auditors. Each is tuned to a specific clinical domain and translates the platform power into specific, compliant interventions. Additionally, our flagship applications, RxAI and Audit.ai, drive the company's expansion into pharmacy distribution and the payer market.
- Wound.ai Precision Audit
- Pain Management verification
- EM/Urgent Care Auto-validation
Built by physicians and technologists who have operated inside the revenue cycle.
How We Work
Build from the inside out.
We don't build technology for clinicians; we build it from their perspective. Every feature starts with a workflow reality.
Plain language always.
Complexity is the enemy of integrity. We translate arcane medical coding and AI outputs into clear, actionable English.
No “Black Box” AI.
Auditing requires accountability. Every AI-driven decision must be explainable, citeable, and transparent.
Precision over Scale.
We would rather be perfectly accurate in one specialty than moderately helpful in ten. Quality is our true metric.
Speed with Certainty.
Integrity shouldn't slow down care. Our platform is built for real-time validation without clinical friction.
