Picture this. A Series A digital health startup just landed a pilot with a regional hospital network. To meet the deadline, the CTO hired a well-reviewed offshore agency. Their portfolio looked solid — fintech, e-commerce, a few SaaS products. Healthcare couldn’t be that different, right?
Six months later, the pilot was on hold indefinitely. The development team had treated clinical data like standard database tables. They misunderstood FHIR resources and HL7 messaging. They assumed encryption at rest was enough for HIPAA compliance — and missed access logging, audit trails, and the BAA entirely. The startup scrapped the architecture, burned six months of runway, and started over with a different vendor.
I’ve seen this scenario play out more than once. A founder comes to us six months after a build decision that made sense on paper — and we spend the first discovery call understanding what went wrong rather than what to build next.
This happens more often than it should. And it’s almost always preventable. According to thePonemon Institute, the average cost of a healthcare data breach reached $9.77 million in 2024 — the highest of any industry. Vendor selection is one of the most direct levers a CTO has over that risk.
Why does healthcare vendor selection work differently from other industries?
In most industries, evaluating a software vendor comes down to tech stack, hourly rate, and communication style. In healthcare, those are table stakes.
Healthcare software operates under compliance constraints that are baked into architecture decisions — not bolted on at the end. A developer who doesn’t understand the difference between a clinical observation and a diagnostic report will design flawed data models from day one. A team that’s never integrated with a live EHR system will discover, mid-project, that the documentation is incomplete and the endpoints behave unexpectedly.
You need a partner who has solved these problems in production before. Not one who will solve them for the first time on your budget and your timeline.
Here’s how to separate those two categories.
How do you verify a vendor’s real HIPAA experience — not just awareness?
Ask the vendor to walk you through how they handle PHI in their own infrastructure. A team with real HIPAA experience will immediately talk about encryption in transit and at rest, access control policies, audit logging, and BAA requirements.
A team without it will say they “follow HIPAA guidelines” and reference their cloud provider’s compliance page.
That last answer is a disqualifier. A HIPAA-compliant cloud provider does not make your application HIPAA compliant. The vendor needs to understand what that means on their side — in their development environment, their staging systems, their internal access controls.
The follow-up question: “Have you signed a BAA with a covered entity before?” Ask them to walk you through what it required technically. The specificity of the answer tells you everything.
What clinical integration experience should a healthcare software vendor have?
Most healthcare products don’t live in isolation. They connect to EHR systems, lab platforms, billing tools, or patient-facing apps. The integration layer is where projects most often stall.
Ask which EHR systems they’ve integrated with — Epic, Cerner, Athenahealth are the names you want to hear. Ask whether they’ve worked with HL7 v2, FHIR R4, or SMART on FHIR. Ask how they handle data mapping when source systems are inconsistent, which in clinical environments they almost always are.
If the vendor has only built greenfield products and has never integrated with a live clinical system, that’s a meaningful gap. Healthcare rarely gives you a clean slate.
How do you match a vendor’s delivery model to your team structure?
Fixed-price project, dedicated team, staff augmentation — each fits a different situation. A vendor who pushes one model without asking about your context first is a yellow flag.
If your internal team owns the product roadmap but lacks engineering depth, a dedicated team gives you capacity without losing control. If you’re still validating the core concept, a fixed-scope discovery phase followed by iterative delivery is more appropriate.
Ask for a specific example where the model they used didn’t fit the client’s situation and what they did about it. That answer reveals more than any proposal.
What QA approach is appropriate for clinical software contexts?
A bug in a consumer app is an inconvenience. A bug in a clinical decision support tool can affect a patient care decision.
Ask whether they have dedicated QA engineers with healthcare domain knowledge, or whether developers review their own code. Ask how they handle automated testing for data transformations — ensuring no data loss or corruption during interoperability exchanges. Ask how they test role-based access control and audit logging under edge cases.
The answer you want is specific, process-driven, and doesn’t require a follow-up to clarify.
How do you find out who actually works on your project?
The senior engineers who appear in the sales process are not always the ones writing your code.
Ask for the names and seniority levels of the specific people who would be on your project from day one. Ask what their retention looks like on long-term engagements. Ask what happens if a key engineer leaves mid-project.
A vendor with a structured delivery process will have clear answers. One who responds with “we have a large talent pool” is telling you they don’t.
How close should a vendor’s portfolio be to your specific clinical problem?
“Healthcare experience” covers a wide range. A wellness app for tracking water intake is not the same as a remote patient monitoring platform for CHF patients. The data sensitivity, integration complexity, and compliance requirements are categorically different.
Ask for a case study that’s close to your specific problem. Ask what the hardest part was. Ask what they would do differently today.
For context on what meaningful healthcare experience looks like: Impressit’s work with Carbon Health — a US-based digital health company — involved DevOps engineering, CI/CD pipeline standardization, and infrastructure migration support for a production clinical system. That’s a different category than building a patient-facing app. Both are legitimate. They’re not interchangeable. Impressit’s guide to custom healthcare software development goes deeper on the types of systems and what each requires technically.
How do you evaluate communication and process transparency before signing?
Miscommunication is the most common reason outsourced healthcare projects fail — not technology.
Ask who your single point of contact is and what authority they have. Ask how decisions get made when scope and timeline conflict. Ask whether you’ll have direct access to the engineering team or whether everything goes through account management.
A vendor who treats you as a technical peer will have straight answers to all of these. One who hedges is telling you something.
What security posture should a healthcare software vendor have beyond HIPAA?
HIPAA sets a floor, not a ceiling. Medical data is among the most valuable on the black market, and healthtech startups are a frequent target. According to the HHS breach portal, over 700 healthcare data breaches were reported in the US in 2023 alone — and the majority involved business associates, not the covered entities themselves.
Ask whether they follow OWASP Top 10 secure coding practices. Ask about SOC 2 compliance, secrets management, and penetration testing cadence. Ask what their incident response process looks like — who gets notified, in what order, within what timeframe.
In a regulated environment, these are not optional questions.
Red flags that end the conversation
They can’t name a BAA they’ve signed. Real HIPAA experience requires having gone through this process with a covered entity. If they can’t name one, they haven’t.
Their “healthcare experience” is a wellness app. Proximity matters. A nutrition tracker is not a clinical system.
They say “our cloud provider is HIPAA compliant, so the app is HIPAA compliant.” This means they don’t understand healthcare security architecture. Walk away.
They agree to everything without pushback. A vendor who doesn’t challenge unrealistic feature requests or timeline assumptions is desperate for the sale. You’ll pay for that in change orders.
They offer a fixed price for a complex EHR integration without a discovery phase. No one can accurately scope this without first understanding the source system. A fixed price without discovery means they’re guessing.
A note on timelines
Custom healthcare software takes longer than most CTOs expect the first time. Integrating with a hospital’s legacy on-premise EHR will surface undocumented endpoints, firewall rules, and data mapping discrepancies that no one on either side anticipated.
A vendor who quotes a delivery timeline without accounting for security audit, penetration testing, and integration troubleshooting phases is either inexperienced or telling you what you want to hear. The right vendor builds those phases into the estimate and explains why they’re there.
Closing thoughts
Choosing the wrong development partner in healthcare doesn’t just mean a delayed launch. It means compliance exposure, compromised patient data, and an architecture you’ll need to rebuild.
The checklist above won’t guarantee a perfect outcome. It will surface the vendors who have actually done this work — and separate them from those who are figuring it out for the first time on your project.
What’s the single question you’ve found most revealing when evaluating a healthcare software vendor?
