We're building the AI-native interoperability platform that makes healthcare data flow—translating HL7 v2 to FHIR and back, so care coordination, compliance, and reporting are never blocked by a mismatched data format.
Health1st was born from a stubborn, expensive problem: healthcare data still speaks a dozen languages at once—HL7 v2 for admissions, FHIR for apps, C-CDA for documents, X12 for claims, NCPDP for prescriptions, DICOM for imaging. Moving information between systems means hand-building brittle interfaces, one at a time, for months.
Our founder, Dhaval R. Desai, spent 17+ years living that problem—building EHR, revenue-cycle, and HL7/FHIR/DICOM integrations at organizations like Kaiser Permanente and Aetna, then as a principal architect through WinFully on Technologies. His conviction: “The technology to move healthcare data cleanly already exists—healthcare just hasn't deployed it correctly. Let's make the format stop being the barrier to care.”
The timing made it urgent. The 21st Century Cures Act mandates a FHIR API in every certified EHR, and CMS-0057-F requires payers to stand up four FHIR APIs by 2027—yet most healthcare data still lives in HL7 v2. That gap is exactly what Health1st closes.
So we built an AI-native interoperability engine: a fleet of agents that draft and validate mappings between any healthcare format and any other—bidirectionally, with a human always in the loop and PHI always under your control. Our mission is simple: make healthcare data flow, so interoperability stops being a project and starts being a given.
These principles guide every product decision, customer interaction, and line of code we write.
Every product decision starts with one question: Does this make healthcare data flow? We measure success by the systems we connect and the barriers we remove — so care coordination, compliance, and reporting are never blocked by a mismatched data format.
We're engineers, not salespeople. Every claim we make is backed by measured results — mapping accuracy, conformance test coverage, and validation against the specifications we support. If we state a number, we show you the methodology behind it.
We publish our accuracy metrics, document the standards and profiles we conform to, and flag transformations that need human review. Trust is earned through honesty about what our engine does — and doesn't yet — not marketing spin.
AI should augment human expertise, not replace it. We build our mapping engine with a human in the loop for ambiguous transformations, because health data integrity is too important for black-box automation.
Good enough isn't. We validate transformations against US Core, Da Vinci, and the source specifications, run continuous conformance testing, and hold every mapping to rigorous accuracy standards. Interoperability demands data you can trust.
World-class interoperability shouldn't require Fortune 500 budgets or an army of integration engineers. We make enterprise-grade data exchange accessible to health systems, payers, and digital-health teams alike.

Founder of WinFully on Technologies, serving as fractional CTO/CIO and principal architect for complex HL7, FHIR, and DICOM integrations.
Expertise:
A founder-led path to making healthcare data flow — from thesis to an AI-native interoperability platform.
Health1st founded by Dhaval R. Desai with a founder-led mission: make healthcare data flow through AI-native, bidirectional HL7 v2 to FHIR interoperability.
Focused the platform on the format problem at the heart of healthcare IT — HL7 v2, FHIR, C-CDA, X12, NCPDP, and DICOM — and the case for an AI-native engine to map between them.
Designed a 12-agent interoperability fleet to draft and validate mappings between healthcare formats bidirectionally, with a human always in the loop and PHI under customer control.
Aligned the platform with CMS-0057-F and the 21st Century Cures Act, engineering for the FHIR API mandates payers and providers must meet ahead of the 2027 deadlines.
Operating under HIPAA with Business Associate Agreements in place today, with SOC 2 and HITRUST certification efforts underway as part of our enterprise security roadmap.
Readying the AI-native interoperability platform for its first design partners — turning interoperability from a months-long integration project into a given.
