We're Fixing How Construction Reads Its Contracts
Stact was built because the Australian construction industry deserves better tools for understanding contractual risk — before it turns into a dispute, a loss, or a collapse.
$7B+ Annual Cost
Construction contract disputes cost the Australian economy over $7 billion annually. Three thousand construction firms collapse every year — many with contract risk at the centre.
27% of All Insolvencies
Construction accounts for more than a quarter of all corporate insolvencies in Australia. Unfair terms, missing protections, and buried risk are recurring factors.
The Problem
Construction contracts are long, complex, and written in legal language that most commercial teams don't have time to fully review. Risk is buried in clause interactions, implied by omission, and hidden behind standard form amendments.
How Stact Solves This
Stact's proprietary analysis engine examines every clause across eight dimensions simultaneously — risk transfer, ambiguity, unfair terms, legislative compliance, benchmarking, omissions, cross-clause interactions, and standard form deviation.
Depth Over Speed
We don't skim contracts and we don't cut corners. 314 checks per clause. 10,475 gold-standard test scenarios. Every finding is validated before it ships. If our engine can't prove a finding, it doesn't report one.
Australian to the Core
Stact is Australian owned, Australian developed, and Australian operated. This isn't a US product rebranded for APAC — it was built from day one for Australian construction law, Australian contract types, and Australian jurisdictions. Every algorithm, every check, and every test scenario speaks GC21, AS 4000, and SOP Act. Our team is here, our data stays here, and our product is built for the way Australian construction actually works.
Transparency, Always
No black-box scores. Every finding shows the clause text, the check that triggered it, the severity rationale, and the benchmark data behind it. If we can't explain why, we don't flag it. You can verify everything Stact tells you.
Prevention, Not Litigation
We exist to stop disputes before they start — not to help litigate them after. Every feature is designed to surface risk at the point where you can still do something about it: before you sign.
Levelling the Playing Field
Large principals have teams of lawyers reviewing every clause. Subcontractors and smaller contractors don't. Stact gives every party in a contract the same analytical depth — regardless of their legal budget.
Built to Be Proven Wrong
We don't hide from scrutiny. Our test suite is our quality guarantee — 10,475 scenarios that run against every code change. If our analysis can't pass the gold tests, it doesn't ship. Full stop.
