The problem
A construction site is thousands of small problems.
A late delivery. A crack in apartment 304. A plan revision nobody saw. None of them is hard on its own — together they make a mess no one can hold in their head. Biilby holds the whole picture, so every person on site only deals with their simple piece of it.
BiilbyBiilby manages the complexity. You see simple things.
How it works
Three steps. No setup, no training.
Feed it everything
Plans, BoQs, schedules, site photos, issues. Drop them in as they are — no template, no data entry, no admin.
Biilby connects it all
It reads your documents and understands how they relate: which issue touches which activity, which revision changes which quantity. In real time.
Ask anything, anywhere
From the office or the scaffolding. You ask, you get. If you can use WhatsApp, you already know how to use Biilby.
For every actor
One site. Everyone gets what they need.
The electrician, the site manager, the PM, the director — each one asks, each one gets exactly what they need. Nothing more, nothing less.

Why Biilby
Why teams pick Biilby over the rest.
Built for the site, not the office
It works in the rain, with gloves, on the phone already in your pocket. The heavy tools were designed for a desk — and stayed there.
Chat, not dashboards
Nobody adopts a dashboard. Everybody already chats. That's the whole reason Biilby actually gets used by the people on site.
It connects — it doesn't just store
Other tools are filing cabinets you still have to read. Biilby understands how a crack, a plan and a deadline relate — and tells you.
Enterprise-grade, without the enterprise baggage
Multi-tenant security, SSO, EU hosting and an audit trail — without the heavyweight rollout or a dedicated admin to feed it.
Proactive, not passive
It doesn't wait to be asked.
Biilby watches the whole project while you work: a delivery that slips, an issue that touches the critical path, a quantity that doesn't add up. When something matters, it tells the right person — before it bites.
It proposes. You decide.
Biilby07:42Morning Karim. The window delivery slipped to Thursday — that blocks glazing on level 2 from Monday. Two options: start level 4 partitions early, or resequence glazing. Want to see the impact of each?
Enterprise-grade underneath
Friendly on the surface. Serious underneath.
Biilby is built for companies, not just for chats.
