The Engineering Partner MedTech Teams Call When the Roadmap Can't Slip

From SaMD architecture to FDA-ready device software, CitrusBits embeds with your product team and ships.

Whether you're architecting from scratch or scaling what's already in production — most MedTech teams don't have an execution problem. They have a "finding the right technical partner who actually understands regulated healthcare" problem. That's the only problem we solve.

SaMD Development and Regulatory Engineering

Software as a Medical Device isn't just a classification. It's an entirely different engineering discipline. We architect SaMD products with IEC 62304 compliance, human factors engineering per IEC 62366, risk management documentation per ISO 14971, and FDA pre-submission alignment built into the process from week one. Your Design History File isn't an afterthought. It's how we work.
For MedTech startups pursuing FDA clearance or CE marking on software-driven products

Medical Device Software and Embedded Systems

The software inside your device determines whether it gets cleared, adopted and trusted in clinical settings. We engineer firmware, embedded software and companion applications for connected medical devices where every release cycle carries regulatory consequences. Design controls, software of unknown provenance reviews, verification and validation. Done as part of the build, not bolted on before submission.
For Device manufacturers who need a software partner that understands the hardware it runs on

Clinical AI and Diagnostics Software

We develop AI systems that operate inside regulated medical environments. Diagnostic imaging analysis, clinical decision support, anomaly detection, predictive risk models. Built with algorithm change protocols, validation frameworks and audit trails that FDA and clinical governance teams require. Not prototypes. Production systems with a regulatory pathway from day one.
For AI MedTech startups and product teams commercializing clinical intelligence

XR Healthcare Applications

Through IntelliXR, our extended reality platform purpose-built for healthcare, we develop XR applications for surgical simulation, clinical training, vision diagnostics, therapeutic rehabilitation and patient engagement. Human factors validation, clinical workflow integration and device-level compliance are built into every XR product we ship. These aren't immersive demos. They're regulated, deployable clinical tools.
For Healthcare innovators using VR, AR or mixed reality in clinical or therapeutic settings

Healthcare Software Engineering

Not every healthcare product is a medical device. But every healthcare software product carries clinical, compliance and user experience obligations that generic software shops aren't equipped to handle. We engineer custom healthcare software for clinical workflows, provider operations, patient engagement and care coordination. HIPAA-compliant architecture, clinical UX grounded in human factors principles and software that works the way clinicians and patients actually work.
For Product teams building clinical software, provider tools and patient facing healthcare applications

Digital Health Platforms and Connected Care

We engineer digital health platforms that operate across patient, provider and device layers simultaneously. Remote patient monitoring, chronic care management, virtual care infrastructure, population health and connected health ecosystems. Every platform is HIPAA-compliant, audit-ready and stress-tested for real patient volume before it goes anywhere near a clinical environment.
For Digital health companies moving from early product to clinical deployment at scale

Wearable and IoT Medical Device Software

Wearable medical devices live at the intersection of hardware, connectivity and clinical data. We handle the full software stack. Firmware, BLE and wireless protocols, companion mobile applications, real-time cloud data pipelines and device management infrastructure. Usability engineering and human factors validation included. Built for FDA and CE regulated environments from the ground up.
For IoT and connected device companies who need one engineering partner across the full stack

Digital Therapeutics and Rehabilitation Technology

DTx products face a uniquely difficult challenge. They need to meet clinical evidence standards, pass regulatory scrutiny and still deliver an experience patients actually use. We develop prescription digital therapeutics, biofeedback platforms and rehabilitation technology with human factors engineering, clinical validation protocols and the regulatory depth both requirements demand.
For Therapeutics and rehabilitation technology companies pursuing regulatory approval and clinical adoption

What We're Actually Hired To Do

Not a service catalogue. These are the exact engagements we run for MedTech and HealthTech product teams right now.

Every engagement starts with a senior engineer understanding your product, your regulatory pathway and your timeline. Not a proposal template.

Shipped. Cleared. Running in Live Clinical Environments
Every project below started the same way yours will. A senior engineer, a clear regulatory pathway and a timeline that couldn't move.
XR-based vision rehabilitation platform engineered and shipped in 16 weeks. HIPAA-compliant from day one. Now active across 100+ clinical sites serving tens of thousands of low-vision patients in live programs. Human factors validation completed as part of the build cycle, not after it. What this tells you: Speed and compliance are not a tradeoff when the engineering is right from the start.
Diagnostic and clinical workflow platform integrating immersive XR with live provider systems. Deployed across multiple health systems. Processing hundreds of patient sessions every week. What this tells you: Complex multi-system clinical integrations across real health infrastructure are our standard operating environment.

Johnson & Johnson Secure research platform reducing time-to-insight for medical literature access by 40%. Now used by research teams across multiple therapeutic areas. What this tells you: When the client is J&J, there is no room for anything less than enterprise-grade engineering, security and accountability.
We can't name every client we're currently working with. What we can tell you is that a Fortune-listed medical device manufacturer, a next-generation diagnostic platform and a global ophthalmic leader are all in active development with us right now.
TECHNOLOGY AND COMPLIANCE
The Infrastructure and Standards Your Product Will Be Held To. Already Ours.
Every CitrusBits engagement inherits a technology foundation and compliance posture that takes most teams years to establish.
ISO 27001 aligned development practices
ISO 27701 aligned development practices
ISO 13485 aligned development practices
HL7 & FHIR interoperability standards
HIPAA-compliant architecture for secure patient data handling
GDPR-aligned systems for global data protection and privacy
SOC 2 aligned infrastructure and security controls
These aren't certifications we display. They're the standards your product is engineered against from the first line of code.
What Makes the Difference When the Stakes Are Clinical
There are hundreds of development agencies. Very few have shipped regulated medical products that are clearing patients right now.
The best time to work with an engineering partner who understands regulated healthcare is before your roadmap has already absorbed the cost of one that didn't.

We've seen where MedTech products break.

Not in theory. In production, under clinical load, during FDA audits, inside health system deployments. That pattern recognition is what you're hiring. No agency that hasn't lived inside regulated healthcare can replicate it.

We treat architecture as a clinical decision.

The decisions made in week one of your build determine what your product can and cannot do in year three. We bring clinical context, regulatory foresight and engineering discipline to every architecture conversation before a single line of code is written.

Human factors is how we think, not a deliverable we produce.

Most teams treat usability validation as a document they generate before FDA submission. We treat human factors engineering as a design philosophy that runs through every product decision from wireframe to verification testing. Your users are clinicians and patients. The bar is different.

Compliance is never a separate workstream.

We don't have a compliance team that reviews what the engineering team built. Regulatory alignment, documentation and risk management run alongside development from day one. By the time you're ready to submit, the work is already done.

We stay in the room through deployment.

We don't hand off after development. We don't disappear after launch. We're accountable for how your product performs inside real clinical environments, under real patient load, during real audits. That accountability is what separates an engineering partner from a vendor.

MedTech Startups Post-Funding

You've closed your round. The board wants velocity. Your engineering team needs a partner who can move fast inside a regulated environment without creating technical debt that kills your Series B story. That's the engagement we run best.

Medical Device Manufacturers Adding Software

Your device works. Now it needs firmware, a companion application, cloud connectivity and a software validation package that satisfies your regulatory affairs team. We've done this exact engagement more times than we can publicly talk about.

Clinical AI Companies Going to Market

Your model performs. Now you need a production system built around it. One with the audit trails, algorithm change protocols and clinical validation infrastructure that turns a promising AI into a cleared, deployable medical product.

Digital Health Product Teams

You're building software that operates inside clinical environments. Your team is strong but regulated healthcare has specific engineering, compliance and human factors obligations that require a partner who has been here before. Not one learning on your project.

XR Healthcare Innovators

You're building something that doesn't have a clear precedent in the market. Surgical simulation, XR diagnostics, immersive therapy. You need an engineering partner with both the XR depth and the healthcare compliance knowledge to ship something that actually reaches patients.

Enterprise MedTech and Life Sciences

You're not a startup. Your engineering standards, security requirements and compliance obligations reflect that. You need a partner that operates at enterprise level without the overhead of a Big Four consultancy and without the risk of an agency that has never touched a regulated product.

Built for the Teams Actually Shipping MedTech
Most development partners understand software. Very few understand what happens when that software is responsible for a clinical outcome. We built our entire practice around that difference. Every client below chose us for exactly that reason.
If your product touches patients, clinicians or clinical data, and the engineering has to be right the first time, you're in the right place.
What MedTech and HealthTech Teams Say
300+ projects. 15+ years. Verified on Clutch.

"CitrusBits was willing to go the extra mile. I'm impressed with their patience and their speed. They worked with us when we had questions and put a lot of effort into the project. They were just great people to work with."

"Remarkably dependable from day one through delivery. We never had a single surprise, never had to chase an update, never had to wonder where things stood. That kind of reliability is rare in a development partner."

"The project managers were deeply professional and completely committed to the outcome. But what stood out most was the engineering team — the technical depth they brought to every problem was matched only by how well they communicated it."

"Whatever they take on, they do it exceptionally well. No caveats, no exceptions. Just consistently excellent work across every aspect of the engagement."
