For your health — patient or professional
THE HARNESS
FOR YOUR HEALTH.
You already use AI for your health — asking about a symptom, a lab, a medication. So do your doctors, drafting the note and the prior auth. The harness is the layer that makes it safe: your health conversations stay yours, and a licensed physician stands behind anything that matters.
Any model. A physician behind it. Yours by design.
New here? How the harness works, in 90 seconds →
AI drafts it in seconds — and it is held. No code path sends an unsigned draft to a patient, payer, or record.
Only now does it count — signed by a named physician, and provable years later.
Whoever you are, there's a door for you.
Everyone's health runs through AI now — the patient asking questions at midnight, the clinician drafting notes at scale. The harness is the same layer underneath both. Start where you fit.
Use AI for your health — safely, and privately.
Ask about a symptom, a lab, a medication. The harness keeps the conversation yours — not training data for a company you'll never meet — and puts a licensed physician behind the answers that matter.

“Companies need… a harness to orchestrate the whole thing.”
— Jensen Huang, CEO NVIDIA · June 2026WHAT 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.
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.
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.
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 records already reach Claude. The output isn't governed.
Anthropic and connectors like HealthEx already bring a patient's consented records into Claude — securely, over the federal TEFCA network, via MCP, never used for training. That solves the input. What stays unsolved is the output: when the model interprets a lab, drafts a care plan, or suggests a medication, who signs it?
Consented records in
A patient connects their full history from 50,000+ provider organizations to Claude. Consent-scoped, never trained on. The input layer is solved — securely, over the federal TEFCA network.
See the connectorThe model reasons
The record becomes context. Claude can summarize it, explain a lab, draft a routine. Powerful — and, on its own, ungoverned for clinically meaningful output.
The published evidencePhysician-governed output
Before clinically meaningful output reaches a patient, a licensed physician attests it — NPI-bound, timestamped, audit-anchored. The layer the input pipes do not provide. This is us.
How the hard intercept worksHealthEx put the patient back at the center of their data. The harness keeps a licensed physician at the center of the decision.
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.
Independently proven at the frontier — June 2026
An open agent harness just carried a mid-tier model past the strongest frontier models on the hardest long-horizon engineering benchmark — same model, same budget, only the control loop changed. The finding: independent verification, revisable planning, and disciplined stopping beat raw model strength on work that runs for days. That is this architecture, specialized for clinical AI — where the verifier is a licensed physician and the gate is attestation. Zenith, Frontier SWE →
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.

Technology partners
The health system that works for you.
The builder stack for physician vibe coders.
Two infrastructure partnerships that make physician-governed AI deployable at clinical grade — without building the monitoring platform or the AI orchestration engine from scratch.
The health system that works for you
myon.clinic
MDR Class IIa + FDA cleared. The complete patient experience across eight clinical specialties — cardiology, orthopedics, oncology, gynecology, and four more. Automated treatment pathways, patient-specific thresholds, continuous monitoring between visits. Apple Health / Withings / Garmin wearable integration. What Google Health tried to build and abandoned. FDA clearance is what Google doesn't have.
RTM billing: CPT 98975 + 98977 + 98985 + 98979 = $93–$170/patient/month via enrolling physician NPI.
Health vertical for physician vibe coders
JetBridge Harness
The professional stack for physicians building with Claude. Agent orchestration, model routing, RAG and graph memory, evals and guardrails, voice stack, observability — all in a HIPAA-compatible private VPC. Healthcare pedigree: DoctorBase (9M patients, 18K providers, acquired by Tebra), Invitae, Nest Genomics. Where a physician who wants a personal AI assistant uses Gemini Spark, a physician who wants to build HIPAA-compliant clinical AI tools uses JetBridge + Claude.
Model-agnostic. Claude-native. Private VPC. Every AI call governed, routed, and observable before it touches a physician queue.
The three-layer stack: myon.clinic (the health system that works for you — FDA-cleared continuity across conditions, wearables, and physician oversight) + JetBridge Harness (the health vertical builder stack for physician vibe coders) + the SolvingHealth 50+-site distribution network. No competitor has all three. Health systems that license the stack get FDA-cleared patient monitoring, physician-governed AI, and a patient acquisition network — deployed in under 30 days.
For health systems
Two on-ramps. Less than one FTE to deploy.
Each on-ramp is a contained deployment that proves value in 30 days using existing CMS codes. No EMR rip-and-replace.
On-ramp 1
Post-surgical recovery
SurgeonValue and JointCoach handle prior auth, RTM billing (98985/98979), patient check-in, and outcome tracking. NPI is the login. AI drafts — the surgeon's name stays on the output. $51/patient/month in RTM revenue. $147K missed per surgeon per year, recovered.
See SurgeonValueOn-ramp 2
Discharge-to-home
co-op.care deploys Sage AI for family assessment, autonomous LMN generation (HSA/FSA eligibility), and care coordination. Physician review built in — 50-state licensed. 3–5 minutes per attestation. Runs on existing CMS transition-of-care workflows.
See co-op.careThe same infrastructure. Four entry points.
