Product engineering for connected hardware.

We are a small, senior team helping hardware companies ship the software around their devices — firmware, companion apps, provisioning and the cloud plumbing that keeps them running.

Firmware & bring-up

Board bring-up, RTOS integration and over-the-air update pipelines for devices in the field.

Companion apps

iOS and Android clients that pair, configure and monitor hardware without the usual pairing pain.

Backend & tooling

Device registries, provisioning services and the internal tools your support team actually uses.

A small studio, on purpose.

We take on a handful of engagements a year and work directly with the people who own the product. No account layers, no hand-offs. Most of our clients come from a previous project or a founder we have worked with before.
