Making buildings smarter, one conversation at a time.
nDigi is a Zurich startup building AI-native software for the whole life of a building — from construction and handover to warranty and day-to-day operation. People write what is going on, in their own words; the AI understands it, keeps it in order and suggests the next step. Less administration, fewer disconnected systems, clearer responsibilities for everyone involved.
Designed for the real world.
Software should understand people — not the other way around.
Traditional software asks people to fill in forms and follow a workflow — and on a building site, that is exactly where information gets lost.
We start from the other end: people describe what is happening in their own words and language; the AI understands it, organises it and suggests the next step. AI first, people in charge.
Buildings are complex. Communication shouldn't be.
Handover, defects, warranty, maintenance: the communication around a building is scattered across emails, WhatsApp, spreadsheets and phone calls. Information gets lost, responsibilities blur.
And it does not end at handover — the same building is run for decades. We turn that fragmented communication into clear, actionable information, across the whole lifecycle.
Our product
Meet Bau Assist.
From construction handover to defect resolution — without the communication chaos.
Residents, site managers and contractors communicate in one place. Everybody writes in their own language; the AI helps understand messages, organise defects, translate conversations and suggest next steps.
No complicated forms. No unnecessary administration. Just clear communication — and a record that stays with the building when the next phase begins.
Bau Assist runs in production on real projects in Switzerland.
From unstructured information to clear next steps.
Understands the message
A photo and a sentence in any language become a tidy, translated, labelled entry — spelling fixed, duplicates spotted, the original kept.
Keeps every matter in order
One conversation per matter, with the people on it: who reported it, who is responsible, what was promised and when.
Suggests the next step
Open matters become cards with one-tap actions — assign to the firm that had this trade before, name a day, ask for a photo, close what is reported done.
Adapts to the project
Recommendations follow the project’s context and earlier decisions, and people remain in control of every one of them.
Startup mindset. Enterprise experience.
nDigi combines the speed and ambition of a startup with more than twenty years of experience designing and operating enterprise software — cloud architecture, AI and large-scale systems in demanding environments.
We don’t just design products. We build, operate and continuously improve them ourselves.
AI-native by design
AI is part of the product experience from the first sketch, not added afterwards.
Built end to end
We design, develop, deploy and operate our software ourselves.
Engineered for production
Secure Swiss cloud, automation, monitoring and reliable operation from day one.
