Industries

Different devices, the same discipline.

We focus on device categories where firmware decides whether a product is reliable in the field. Here is what each one usually needs from us.

01

Connected consumer devices

The firmware problem
Battery life, reliable phone pairing and updates that never brick a device in a customer's home.
What we do
Low-power firmware, BLE and Wi-Fi stacks, OTA with rollback.
Common interfaces
BLE, Wi-Fi, USB
02

Industrial equipment & controls

The firmware problem
Long service lives, noisy electrical environments and integration with existing PLCs and SCADA.
What we do
Control programs, fieldbus communication, watchdog and fault handling.
Common interfaces
Modbus RTU/TCP, RS-485, CAN
03

Energy, battery & charging hardware

The firmware problem
Safe charge and discharge control, accurate measurement and remote monitoring.
What we do
Power control loops, measurement firmware, telemetry and remote updates.
Common interfaces
CAN, RS-485, LTE-M / NB-IoT
04

Building & environmental sensing

The firmware problem
Sensors that run for years on a battery and report over long distances.
What we do
Sensor drivers, sleep scheduling, LoRaWAN or cellular reporting.
Common interfaces
LoRaWAN, I2C, SPI
05

Instrumentation & lab devices

The firmware problem
Precise timing, repeatable measurements and a clean interface to host software.
What we do
Real-time acquisition firmware, host protocols, production calibration tools.
Common interfaces
USB, UART, SPI

What we don't take on

Certified functional-safety development under IEC 62304 (medical), ISO 26262 (automotive) or DO-178C (avionics) needs formal verification processes and documentation. We don't claim that capability, so we don't accept those projects. If your product falls in one of those areas, we'll say so on the first call.

Regulation on the horizon

If you sell connected products in the EU, the Cyber Resilience Act applies. Vulnerability reporting obligations began on September 11, 2026, and the main requirements apply from December 11, 2027. Obligations sit with the manufacturer. We help with the engineering side: threat modeling, SBOMs, secure boot, signed updates and a security-fix process. We don't issue certificates.

Not sure your device fits?

Describe it briefly and we'll tell you honestly whether we're the right team.
