The Technical Requirements Are Tighter
A missed deadline isn't slow UX — it's a clinical failure. Memory and power constraints are fixed before the software team even arrives.
Award-Winning Medical Device Software
Why Medical Device Software Is Its Own Discipline
Every decision has to hold up across three dimensions at once — right on one can be wrong on the others.
The Regulatory Requirements Are More Demanding
IEC 62304, ISO 14971, IEC 62366, 21 CFR Part 820, and 2023 FDA cybersecurity guidance — with post-market obligations long after clearance.
The Consequences of Failure Are More Serious
A bug in a consumer app is a bad experience. A bug in infusion pump firmware or ventilator control software is a patient safety event.
Device Categories We Build Software For
Embedded systems, firmware, and device control software — each with its own safety class and regulatory pathway.
What FDA Regulation of Device Software Actually Requires
The five frameworks that shape every decision.
IEC 62304 — Software Lifecycle
Three safety classes (A/B/C) based on harm severity. Class C applies when failure could cause serious injury or death. Most therapy and monitoring software lands Class B or C — full lifecycle documentation required.
21 CFR Part 820 — Design Controls
Design planning, inputs, outputs, verification, validation, and transfer — all documented as you build. Design control gaps are the most common FDA inspection finding. We build the record during development, not before submission.
ISO 14971 — Risk Management
Hazard identification, risk estimation, control, and residual evaluation for every risk-contributing component. A living analysis that shapes design decisions, not documents them after.
FDA Cybersecurity Guidance 2023
Threat modeling, a Software Bill of Materials, patch management planning, post-market cybersecurity monitoring, and coordinated vulnerability disclosure. Required for networked devices at submission.
IEC 62366 — Usability Engineering
Use-related risk analysis, formative studies during design, and summative validation with real users. Usability failures are a leading cause of 510(k) additional information requests.
How We Build
Ordinary embedded work. Extraordinary process.
-
Requirements to IEC 62304
Requirements to IEC 62304
Precise, verifiable, traceable — not user stories. This phase takes longer and prevents late-stage problems that cost far more.
-
Architecture for the Full Lifecycle
Architecture for the Full Lifecycle
RTOS, memory, bootloader, and communication protocol chosen with post-market maintenance in mind — not just immediate development.
-
Verification Designed In
Verification Designed In
Test protocols written against requirements, not code. Every requirement traces to a test case through the full lifecycle.
-
Hazard Analysis Covers the Edge Cases
Hazard Analysis Covers the Edge Cases
Boundary conditions, race conditions, power loss, and concurrent events that clinical environments produce — not just nominal operation.
-
Regulatory Docs Built During Development
Regulatory Docs Built During Development
Software Description, Development Plan, Requirements Spec, and V&V documentation — produced as the software is built, not reconstructed at submission.

Frequently Asked Questions
[ 1 ]
How is this different from regular embedded development?
Same technical content, different rigor: traceable requirements, risk analysis, and design controls an FDA investigator can review.
[ 2 ]
What safety classification will our software be?
Set by risk analysis during discovery. Most therapy, monitoring, and alarm software is IEC 62304 Class B or C.
[ 3 ]
Can you work alongside our hardware team?
Yes — our most common model. We work from your specs, schematic reviews, and joint hardware bring-up.
[ 4 ]
How do you handle FDA submission preparation?
We build regulatory documentation during development, so it already exists at submission time. We work with your regulatory affairs team.
[ 5 ]
What happens when we need to update software after clearance?
Post-market change management is built in from the start. Updates follow the same design control process.
[ 6 ]
Who owns the IP?
You do. Full transfer at close — source, design docs, test protocols. No per-device licensing fees.
