Embedded in connected systems

Firmware is architected with the connected system in mind.

Firmware sits on your critical path, is the most expensive to change, and, in medical devices, carries the highest safety risk. Poor firmware decisions cascade through your entire product.

We architect embedded software with a system-level perspective. Because we work across devices, mobile, cloud, and electronics, we design for the full system and not just the embedded layer.

The Result: Firmware that integrates cleanly with your connected system, scales to production, and supports your regulatory pathway without blocking development.

WHAT YOU GET

Production-Ready Firmware with Engineering Traceability

We deliver tested, traceable firmware with the build systems, verification evidence, and documentation that regulatory teams require.

Vignette Embedded Deliverables Dark

Firmware development requires more than working code. You need to build systems, test infrastructure, traceability matrices, and verification evidence that support regulatory submission and long-term maintainability.

wOur deliverables create an auditable trail from requirements through release, essential for products that scale, transfer between teams, or require regulatory approval.

  • Design: Traceable requirements, architecture, and design documentation that integrates with your broader system definition.
  • Development: Version-controlled, reviewed source code developed against requirements and design, with build systems and toolchain configuration for reproducible builds.
  • Verification & Validation Evidence: Requirements verification, risk-based unit and integration testing, plus verification plans, protocols, and reports. 
  • Release: Traceable software artifacts, SBOM, vulnerability analysis, and unresolved anomaly reports.

CLiC™ is Cardinal IG’s smart privacy glass, and after more than ten years of development it entered full-scale production in 2026.

A pane switches from clear to private in under a tenth of a second, with no tint or distortion, and ties into smart home and building control systems.

For a home or a hospital room, that means privacy on command with no blinds or drapes. It also means a window that is now a connected device, one that has to stay secure and keep working for as long as the glass does, and be built the same way for every manufacturer who puts it into a window, glass door, or glass partition.

DermapenWorld’s Dp4™ microneedling pens are used in clinics around the world, all kept current through a companion app.

The Dp DOCK™ is where a pen sits between treatments. It syncs the pen to the app, installs firmware updates, watches its battery, and will not let it be stored with a needle cartridge attached.

For a practitioner, that means a pen that is current and ready for the next treatment without anyone thinking about it. It also means a dock that has to work with every version of the pen and app in the field, in a clinic where it will never get a second look.

Envoy built the first FDA-approved hearing device that lives entirely inside the body.

The Acclaim™ Cochlear Implant is designed for severe hearing loss, with a sensor that uses the ear’s own anatomy to capture sound in place of an external microphone.

There is nothing to take off before sleeping or showering. There is also nothing easy to power, charge, or connect, and the parts other implants keep outside the head are sealed inside, out of reach without surgery.

A global fashion brand’s smartwatches reached millions of wrists across several product generations, and they were designed to look like watches first.

Under the face they tracked health and activity, moved logs and firmware updates to a phone over Bluetooth, and ran on a battery sized for a fashion case.

For the wearer, that meant a watch chosen for how it looked that still did what a smartwatch does. It also meant pairing with every phone and OS version its wearers owned, each handling Bluetooth its own way, at a scale where a one-in-a-million quirk came up every day.

Hyperice’s Core™ Meditation Trainer is a handheld device you cup in both palms, with heart sensors in the handles and a pulse you breathe along with.

It reads heart rate and heart rate variability to tell when you have settled into a focused state, and the app’s guided sessions respond to that.

For someone who wonders whether they are meditating right, that means a device that can tell them. It also means a consumer product whose first act out of the box is updating its own firmware over Bluetooth, in a living room, where a failed update is a returned product.

Inspire® is the first FDA-approved neurostimulation therapy for moderate to severe obstructive sleep apnea.

A small implant stimulates the nerve that controls the tongue in time with the patient’s breathing, and a connected system sits around it, with a Bluetooth remote the patient holds, an app, and a clinician web portal that monitors the implant wirelessly.

For someone who could never live with a mask, that means sleeping with nothing on their face and starting therapy with a click. It also means the system around a Class III implant has moved through several device generations while every implant already placed stays in a body for years, so no part of the system can change without accounting for every implant in the field.

Portal Diabetes holds FDA Breakthrough Device designation for the Portal Pump™, an implantable insulin delivery system.

The pump is designed to sit in the abdomen, dose from a continuous glucose monitor with a heat-stable concentrated insulin, and take refills in a clinic after weeks or months.

For someone with type 1 diabetes, that means no carbohydrate counting, no meal announcements, and no waking in the night. It also means a loop that closes with no one in it, which has to be trusted before it is ever implanted and then stays in for five to seven years.

A stealth-stage medical startup is developing an implanted neuromodulation therapy that its clinicians can adjust without the patient in the room.

For the patient, that means a therapy that changes when it needs to instead of at the next appointment.

It also means every adjustment travels from a clinician’s screen to a device inside someone’s body, and that path has to be trusted at Class III stakes before anything is implanted.

Synchron ran the first FDA-approved clinical trial of a permanently implanted brain-computer interface, and all six patients met the primary safety endpoint.

The Stentrode® is placed through a blood vessel, with no open brain surgery, and sits in a vein beside the motor cortex reading the intent to move.

For someone with severe paralysis, that means texting, browsing, and opening apps by thought alone. It also means the connection out of the body is the whole product, at Class III stakes. Nothing the implant does reaches a screen unless that link holds.
