Why us

What sets us apart

Not a standard agency, not an interchangeable contractor. We understand technology down to the bit level.

01

Full-Stack to Bare-Metal

From browser frontends through server backends down to microcontroller firmware. We master the entire stack, not just the upper layers.

02

Security by Design

Security is not a feature bolted on at the end. We think encryption and data protection into every project from the start.

03

Transparent and Reproducible

Open-source experience shapes how we work. Every decision is documented, every step reproducible.

Flagship Project

SimpleGo

Our public showcase project demonstrates what we can do - from hardware to protocol.

Open Source - AGPL-3.0
