TRUST IS THE OPERATING SYSTEM
OF MEDICINE.

We're building the infrastructure that protects it. Physician-attested AI orchestration with hard-intercept safety architecture and a 50-state attestation network. Open architecture. Audit chain. Cooperative governance.

WHAT WE BUILD

A 50-state physician attestation network (altru.care)

A peer-review marketplace with named clinicians (ClinicalSwipe)

An audit chain that links every AI output to the physician who attested it (Hashcare)

Domain-tuned agents for surgical practice, registry abstraction, and clinical documentation (SurgeonValue)

Together: the operational stack that makes physician-attested AI deployable at scale.

AI in healthcare has a governance problem.

Three failure modes are driving institutional anxiety about AI deployment.

01

Unsigned clinical output

AI drafts a care plan, a prior authorization letter, or a medication recommendation. Nobody reviews it. It reaches the patient. When something goes wrong, the liability chain is unclear.

02

Credential laundering

An AI model trained on medical literature generates confident clinical language. No NPI number is attached. No licensed physician reviewed it. The clinical authority is borrowed from training data, not from a real doctor.

03

Fragmented identity

A patient engages with AI across six different health apps. There is no unified identity, no shared medical context, no way for a physician to maintain a coherent longitudinal view of that patient's health journey.

The architecture

The harness is the governance layer
you don't see.

Four components. One governed infrastructure. Every AI call in the ecosystem passes through all of them.

NPI Registry

2.4M licensed physicians

The CMS NPPES registry, pre-indexed. Every NPI maps to a page at harnesshealth.ai/dr/[NPI]. Physicians claim and enrich. Health systems query via API. Zero signup required for a physician to have a page.

Attestation Engine

AI generates. Physicians attest. Cryptographic record.

Every clinical output routes through the physician attestation queue. Reviewed in 3-5 minutes. NPI-bound. Authority consumption tracked to prevent rubber-stamping. Immutable audit log.

Embed Network

45+ live sites on footer.js

One line of JavaScript. Patient intake, PROM collection, Reed AI, physician connection. Deployed to 45+ sites. Change once at the source — every site updates.

API Gateway

Every AI call is governed.

solvinghealth.com/api/chat — the governed Claude bridge. HIPAA transport. SSO across all 45+ sites via Supabase. Hard intercept enforcement. Open-source FHIR connectors. Proprietary intelligence layer.

Live infrastructure, not a roadmap.

What is deployed and running today. What is in process. The honest accounting is a governance signal, not a hedge.

“The moat is whoever first connects grounded clinical evidence to native multimodal output, real workflow extensibility, and physician-earned trust.”

HarnessHealth provides AI governance infrastructure for healthcare, not medical advice. All clinical outputs are supervised by licensed physicians. Consult a qualified healthcare provider for diagnosis and treatment.
