Healthcare & Regulated
We build for healthcare, fintech, and other businesses where the architecture, the audit trail, and the bedside manner of the engineering team all matter at once. Critonyx is the software partnership for operators who can't afford a vendor that learns compliance on their project.
In healthcare, a misconfigured access control is a HIPAA breach. In fintech, a missed audit log is a SAR enforcement action. In any regulated business, the difference between an "acceptable" vendor and a defensible one shows up the day an auditor walks in, an incident happens, or a regulator opens a file.
The pattern is consistent. A team picks a general-purpose vendor because the price is right. The build ships. Eighteen months later, the team is rewriting the whole system — not because the software didn't work, but because the audit trail didn't, the access controls didn't hold up under review, or the data residency couldn't be defended.
We exist for the operators who've either seen that movie before — or are smart enough not to want to.
Our commitments
Most vendors bolt compliance on at the end. We build it into the architecture from the first commit. Audit logs that can't be turned off. Access controls expressed in code. Data flows mapped before the database schema is written. The audit isn't a project — it's a side effect.
The single most expensive mistake in regulated software is a smart generalist learning compliance on your project. Every engagement is staffed by engineers who've already shipped in HIPAA, PCI-DSS, SOC 2, GDPR, or local equivalents.
Sometimes the most expensive thing a regulated operator can do is build software they don't have the organisational maturity to operate. We'd rather lose the build and earn the trust than take your money and watch the system fail under audit.
EHR-adjacent applications, patient portals, telehealth platforms, clinical decision support tools, lab and imaging integrations. Built with HIPAA, HITECH, and local healthcare frameworks baked into the architecture — and shadowed by clinicians before a single screen is designed.
Lending platforms, payment infrastructure, KYC/AML workflows, transaction monitoring, audit-grade reporting. Built with the controls that hold up under SBP, FCA, FinCEN, or whichever regulator you actually answer to.
HL7 v2, FHIR, X12, ISO 20022, SWIFT — the standards that move data between hospitals, labs, banks, insurers, and clearing systems. Built with retries, idempotency, audit logging, and end-to-end traceability.
We move you off without losing the history, the audit logs, or the regulatory continuity. Strangler patterns, parallel running, cutover plans defensible in writing.
Compliance dashboards, case management systems, regulatory reporting automation, incident response platforms.
Step 1
Book a 30-minute call. Bring the build idea or the existing system, and the regulatory context. Within five business days, you'll receive a free written memo — five pages — covering the regulatory surface, the three architectural decisions that matter most, and our honest take on whether the proposed build is defensible.
Step 2 — when the memo justifies it
A one-week paid engagement. You walk out with a mapped view of the regulatory surface, the architectural decisions that will make the system audit-defensible or audit-fragile, a build-vs-buy-vs-partner recommendation per component, realistic cost and timeline modelling, and a written brief — architecture, controls map, and risk register — that your compliance team can actually use.
"Their architecture passed our SOC 2 audit on the first attempt. We've never had that with a vendor before."
What happens next
Free.
Within 5 business days. Five pages. Yours to keep, even if we never work together.
One week. Recommended if the memo surfaces architectural complexity.
Compliance work scoped in, not bolted on.
Most engagements have working software with controls in place in 8–14 weeks.
Regulated software is never finished.
Ready to talk
If you're standing in front of a build decision and the regulatory weight of it is keeping you up — that's the conversation we want. Thirty minutes. No deck, no pitch. We'll tell you what we'd do in your seat, with a clear answer either way. If our honest read is that you shouldn't build, you'll be the first to hear it.
