You know what you want your device to deliver. We help you get there faster, and better.
You bring the product vision. We bring a proven stack, the engineers who wrote it and 20 years of pitfalls already mapped, so your team spends its time on what makes your product different.
We don’t only use our own stack. We work with chip vendors’ stacks too, and often combine the two, choosing whatever is right for your product. And because we build this technology ourselves, we know it better than anyone.
FASTER
Start on week one, not month four.
Drivers, OS, connectivity and security arrive already integrated, so your team writes product features from the start instead of plumbing.
BETTER
Every lesson from 100+ products, built in.
Range, power, security and certification problems get caught in design review, when they’re cheap to fix.
FOCUSED
Your engineers on your edge.
We handle the layers every connected product needs. Your team owns the features customers actually buy it for.
From the Data to the Cloud
Most connected products are assembled from four or five vendors: a design house, the chip vendor’s SDK, a security library, an IoT cloud. Each one is fine on its own, and each one is a generation behind by the time it ships.
We build on our own advanced technology, from the newest radios to on-device AI, and combine it with the vendor’s stack where that’s the better fit, so your product starts ahead instead of catching up.
Every layer, from the hardware to the AI.
Run the whole stack or drop in a single layer, on NoxOS or Zephyr. Every piece is built, tested together and supported by our own engineers.
Works with
YOUR APPLICATIONReady to go on day one, then customized to your product. We build the app on top of the stack, or you build your own.
NoxML
Edge AI. Runs trained models on the device.
NoxTLS
Security. TLS 1.0–1.3 and crypto in ~40 KB.
NoxCrash
Crash management. A debugger on every device in the field.
NetNox
Networking. TCP/IP with IPv4 and IPv6.
BlueNox + radio stacks
Bluetooth Classic, LE and LE Audio, Sub-1 GHz and 802.15.4.
NoxOS
Operating system. A real-time OS built for microcontrollers.
NoxDrivers
Device drivers for ST, Nordic, TI and more.
YOUR HARDWAREUse your board, or we design it: microcontroller, radios, sensors and antenna, ready for manufacturing.
Other teams integrate SDKs. We build them.
When a vendor library misbehaves, most teams file a ticket and wait. We wrote every layer of the Nox stack ourselves, so when something breaks we know what’s happening. And we integrate into the systems you already have: your chips, your stack, your cloud.
TEAMS BUILT ON SOMEONE ELSE’S SDK
- Glue closed libraries together and hope they agree
- Debug with printf and guesswork
- Wait on the vendor’s release cycle for a fix
- Start over when the chip changes
ARGENOX
- Wrote the stack, from drivers to AI
- Trace problems to the register, packet and line of code
- Fix the root cause on your schedule
- Same code across ST, Nordic, TI and more

Sensor to cloud, one unbroken chain.
A connected product depends on four things holding up: the radio link, the secure channel, the intelligence on the device and the fleet behind it.

13 years of fixing what others shipped.
We kept seeing the same failures on client projects. Security added in the last month. A vendor Bluetooth stack nobody could change. Bugs that were not caught because no one validated. Thousands of units in the field with no way to update them.
So we built our own technology for each of those, and an engineering team that knows how to put it all in one product.
Products we helped bring to market.
A Bluetooth module that reached nearly 200 m.
Bluetooth LE · RF design
Range fixed. Certified. Shipped.
Antenna design · Certification
One BLE platform for a whole product line.
Bluetooth LE · Mobile app

Bluetooth LE · Rescue
