Building the future of building services

AI-powered software for building services.

We build intelligent software solutions for engineers, electricians, and HVAC specialists. Diagnostics that think. Compliance that automates. Tools that work as hard as you do.

The trades are drowning in paperwork,
not building.

AI tools built by tradespeople, for tradespeople

Building services professionals are some of the most skilled people in the workforce. They keep buildings safe, warm, and powered.

But they're using paper forms from the 1990s, diagnostic manuals that haven't been digitised, and compliance workflows that assume you have a back office.

The software that exists was built by people who've never held a multimeter. It doesn't understand the job. It adds friction instead of removing it.

We're different. We build from 30+ years of trade experience, powered by AI that actually understands the work.

Software that speaks your language.

Every product is built from real-world trade experience. No Silicon Valley guesswork. No features you'll never use. Just tools that solve the problems you actually have.

Voice-First

Your hands are full. Your phone's in your pocket. Our tools work by voice — describe what you see, get answers you can act on. No scrolling through menus on a ladder.

📡

Offline-Capable

Basements don't have WiFi. Plant rooms don't have 5G. Core diagnostic data lives on your device. AI enhancement when you're connected, full functionality when you're not.

🧠

AI That Understands the Job

Not generic AI bolted onto a form. Our models are trained on real manuals, real fault codes, real regulations. They understand the difference between a lockout and a reset.

🔒
