What changes for you

Medical AI with
clinician oversight

Domain-tuned LLMs that support clinical decisions while keeping a clinician in the loop.

  • Domain-tuned on clinical corpora

    We select models tuned on de-identified clinical data - MedLLM-class models, Meditron, clinical variants of Llama - grounded on SNOMED CT, RxNorm, ICD-10/11 and your institution's formulary. The model knows the ontology, coding conventions and terminology your clinicians use.

  • Compliance architecture from day one

    BAA signed before the first API call. PHI handling documented in the system design. Audit logs for every clinical output - model version, prompt, output, confidence score, clinician action. Your compliance and legal teams review the architecture before we write any application code.

  • Clinician-in-the-loop on every high-stakes step

    Confidence thresholds, not just guardrails. Below the threshold, the output enters a clinician review queue with the model's reasoning, evidence citations and confidence score visible. The clinician approves, modifies or overrides - and every decision is logged.

Where most integrations break

Why generic LLMs hallucinate clinical content

Ungrounded models invent clinical facts; we ground every answer in your content.

Who we work with

Built for the clinical compliance lead

Whoever owns clinical safety: we build grounded, guardrailed, auditable models.

CMO · Chief Medical Officer

We want AI in clinical workflows. Our compliance team keeps blocking it.

We bring the compliance architecture to the first meeting - not the last. BAA, PHI handling, audit logs, clinician-in-the-loop design, clinician-reviewed eval suite.
  • BAA day one · PHI handling documented before code
  • Clinician-reviewed eval suite before production access
  • Compliance architecture deck ready for your review board
CTO · VP Engineering · Healthcare

We've tried GPT-4o for clinical notes. The hallucination rate is unacceptable.

General models aren't designed for clinical accuracy. We use domain-tuned clinical models grounded on SNOMED, RxNorm and ICD-10 - with hallucination scoring on clinical entities specifically.
  • Domain-tuned clinical models · SNOMED/RxNorm/ICD grounding
  • Clinical entity hallucination scoring on eval set
  • Eval harness with clinician sign-off before production
VP Operations · Hospital / Health Network

Prior auth is consuming 40% of our clinical admin team's time.

PA automation that reads clinical notes, matches payer criteria, drafts the letter with evidence citations, and flags likely denials. Clinical staff review and submit - they don't write from scratch.
  • ↓ 4d → 4h per PA request
  • Payer criteria library maintained and updated
  • Denial pattern analysis and appeal drafting
Head of Digital Health · Health Tech

We're building a patient-facing product. We need clinical AI that won't get us sued.

Patient-facing clinical AI with confidence thresholds, hard-stop topics, escalation paths, PHI handling and a compliance architecture your legal team can review.
  • Confidence thresholds · hard-stop topics · escalation paths
  • PHI handling · HIPAA-aligned · BAA in place
  • Clinician escalation path documented and tested
CISO · DPO · Healthcare

We need full visibility into what the clinical AI is doing with patient data.

Audit logs for every clinical output: model version, prompt, output, confidence score, clinician action. Queryable. Exportable to your SIEM.
  • Audit log per clinical output · PHI handling documented
  • De-identification at the edge for any external data
  • SIEM integration · queryable audit records
CMO · Head of Revenue Cycle

Our coders are backlogged and coding accuracy is slipping.

MedLLM-powered ICD suggestion doubles coder throughput. Coders review AI suggestions instead of coding from scratch.
  • ↑ 2.1× coder throughput
  • ICD-10/CPT suggestions with supporting text from clinical note
  • Coder review workflow · override logging
