Move clinical and AI data safely, reliably, and at national scale.
Deploy integrations in days while maintaining full governance and traceability — one governed transport layer for clinical workflows, AI agents, and health data.
Deploy integrations in days while maintaining full governance and traceability — one governed transport layer for clinical workflows, AI agents, and health data.
The high-speed rail network for clinical and AI data — integration, discovery, and communication working as one coherent system.
A production-grade Health Information Exchange built on the OpenHIE (Open Health Information Exchange) mediator pattern. Standards-compliant interoperability for FHIR, HL7v2, CDA, X12, DICOM — through a single orchestration layer. No translation layers. No middleware adapters.
A global directory where healthcare AI agents register capabilities and callers discover them across organisational and national boundaries. Patient data never enters the registry.
Secure clinical delegation chains. When a triage agent needs imaging, Nexus handles the trusted handshake — with 13 security checks on every call.
See the three capabilities working together — governed personas driving real journeys across the platform and the clinical systems it connects.
Electronic health records that don't talk to each other. Claims systems that create friction instead of reducing it. And now — a wave of AI agents arriving with no standard way to discover, trust, or coordinate with each other.
Every integration is point-to-point. Every trust relationship is bespoke. Every jurisdiction is an island.
BulletTrain is the high-speed rail network for clinical and AI data — one governed transport layer that connects everything.

"Connect once. Orchestrate every clinical and AI workflow."
Once the transport layer is unified, AI agents become deployable as first-class citizens — discovered through GHARRA, delegated through Nexus A2A, and reasoned with Bevan LLM. Governance, consent, and audit hold end-to-end.
Disconnected → Unified → AI-Enabled. One platform; three stages of the same transformation.
Not features. Not capabilities. Results that your board and your clinicians both care about.
Deploy new system connections in days, not months. No re-engineering required. Your existing estate stays in place while BulletTrain connects it all through governed, standards-native channels.
AI workloads are isolated from clinical data by architecture. Patient data stays local. External models only see what they need. Every interaction is consent-gated and purpose-limited.
Every data movement is traced, audited, and compliant. Hash-chained audit trail. Emergency break-glass guaranteed. No clinical data movement escapes the governance layer.
Clinicians make life-or-death decisions under impossible constraints — incomplete information, cognitive overload, and relentless time pressure. We exist to change the decision environment itself.
Herbert Simon showed that humans don't make optimal decisions — they make the best decisions their constraints allow. In healthcare, those constraints cost lives.
We call the solution Grounded Rationality — clinical reasoning anchored in complete, integrated patient context rather than fragmented glimpses.
| Barrier | What Happens Today | How BulletTrain Solves It |
|---|---|---|
| Incomplete records | Clinicians see fragments from one system | Patient360 assembles the full longitudinal view |
| Cognitive overload | 40 patients/day, thousands of guidelines | AI agents summarise, cross-check, and flag |
| Time pressure | 7 minutes per consultation on average | Voice-first interaction, automated workflows |
| Siloed AI | Each AI tool is its own island | Nexus lets agents discover and delegate |
| Trust gap | No way to verify an AI agent across borders | Global Agent Registry with cryptographic trust |
| Governance deficit | Data moves without audit trails | Hash-chained, consent-gated, fully traceable |
We compress the three constraints that limit clinical decision-making: incomplete information, cognitive overload, and time pressure.
Every AI recommendation in Symphonix remains subject to human validation. Our agents augment clinical judgment — they never override it.
Bevan LLM — our healthcare-native AI, named after the founder of the United Kingdom's National Health Service.
"The NHS will last as long as there are folk left with the faith to fight for it."— Aneurin Bevan, 1948
Aneurin "Nye" Bevan created the UK National Health Service in 1948 — healthcare available to all, free at the point of use, based on need not wealth.
We named our AI after him because intelligent healthcare reasoning should be available to every health system, not just those that can afford proprietary cloud AI.
Bevan runs locally inside your infrastructure. No patient data ever leaves the premises.

BulletTrain is free to deploy on your own infrastructure. GHARRA is a managed agent registry hosted by Symphonix Health — subscribe to agents as you need them. An integration bridge connects every BulletTrain installation to the full agent ecosystem.
Whether you're integrating hospitals, deploying AI agents, or building national-scale infrastructure — start with a conversation, not a contract.
Beyond BulletTrain, GHARRA, Nexus A2A and Bevan LLM, the platform now orchestrates a growing suite of clinical and operational systems — provider and citizen portals, prescribing, pharmacy, laboratory, radiology, ambulance dispatch, claims, ERP and more. And every workflow is exercised by persona-driven journeys — executed by governed personas and evidenced by SignalBox.
Every system connected to every other system. No governance. No agent discovery. No orchestration. Complexity grows exponentially with every new connection.
Every clinical system, AI agent, and payer workflow connects once through BulletTrain. FHIR, HL7v2, CDA, X12, DICOM, SNOMED CT, ICD-10/11 — one governed orchestration layer built on the OpenHIE mediator pattern.
AI agents register capabilities and trust credentials. Other agents discover them across organisations and borders. Patient data never enters the registry. Like DNS for the internet — but for healthcare AI.
Every agent-to-agent request is validated: identity, trust chain, clinical scope, data sovereignty, governance policy, audit integrity, and emergency override. Not once per session — every single request.
BulletTrain orchestrates. GHARRA discovers. Nexus A2A governs. Together, they form the governed connectivity platform for health systems deploying AI at national scale.
