Every project already holds the answer.

It is just trapped across twelve systems that were never built to talk to each other. Bildstak is the vertical AI platform that connects them — so a whole project can answer one question, in plain language.

Construction drowns in data and starves for answers.

One project runs on a dozen systems. The model is in Revit. Coordination is in BCF. Cost lives in SAP or Maconomy. RFIs sit in Procore. The schedule is in Primavera. The contract is a PDF nobody has fully read.

Construction generates more data than almost any industry — and uses less of it than almost any. McKinsey, KPMG and Dodge each put the cost of those information gaps at 8–15% of project value. On a $100M job, that is $8M to $15M lost in the space between systems.

The join key was hiding in the model the whole time.

We came from VDC trailers and project-controls desks. We had lived the Monday-morning ritual: six logins, three spreadsheets, and a number you still could not defend.

Then the obvious hit us. Every element in an IFC model already carries a GlobalID — a stable identifier that survives every export. The industry had a primary key all along and had never used it to join its data. That is Bildstak: index every source by the GlobalID, and the whole project reconnects.

Make every system on a project queryable as one.

One question, in plain language, answered from every connected source — with the exact row, activity, clause or page it came from. No SQL. No data team. No black boxes.

The BIM model and its identifier are the source of truth. Everything else reconnects to it.

Five things we will not compromise.

Toronto-built, remote-first, your data where it must live.

We are headquartered in Toronto and remote across Canada, hosting in AWS Canada Central with European residency in Helsinki — and customer-VPC or fully air-gapped where the work demands it.

We hire engineers with real AEC instincts, customer leaders who have run jobsites, and people who would rather ship something dependable than something loud.

Help us reconnect an entire industry’s data.

If construction data is the problem you cannot stop thinking about, we should talk.
