Built by heavy industry people, for heavy industry people.
Hevi wasn't built by a tech company that discovered mining and construction. It was built by two engineers who spent their careers on site — and got tired of watching the same money leak from the same contracts, project after project.
Spend a decade administering contracts in heavy industry and you learn something uncomfortable: 5–10% of contract revenue is at risk or missed — not because people are careless, but because contracts are complex, site teams aren't lawyers, and the tools everyone uses were never built for the job.
SharePoint stores the documents. Excel tracks the register. OneNote holds the meeting notes. Nothing reads the contract. Nothing watches the diaries. Nothing counts down the time bars.
We watched the same three failures repeat on every project we ever worked on — so we built the thing we always wished we had.
Nobody reads the contract
The obligations sit in a 500-page PDF that nobody opens until something has gone wrong.
Nobody operates in black and white
Notices go out late, processes get skipped, and entitlements die on technicalities.
Nobody keeps good enough records
When the dispute lands, the evidence isn't there — and claims settle for half of what they're worth.
An unusual founding team, on purpose
Most contract software is built by legal-tech people for legal teams. Hevi is built by the people it's for.
Paul Culvenor
Paul spent over a decade in commercial leadership roles with Australia's leading contractors — underground and surface, claims and counter-claims, the monthly grind of progress claims and the occasional seven-figure dispute. The problem Hevi solves is the job Paul used to do.
Brad Gyngell
Brad is a drill and blast engineer who went on to build AI platforms now used on thousands of sites worldwide. He leads everything technical at Hevi — the product, the AI architecture, and the security posture that gets us through Tier 1 IT review.
The principles behind the product
Purpose-built, not adapted
Not a legal CLM repurposed for site teams. Not generic AI bolted onto a document store. Built from day one for the contracts heavy industry actually runs.
AI is the how, not the point
We don't sell artificial intelligence. We sell notices served on time, claims that hold up, and records that win disputes. The AI is just how it's delivered.
Every answer carries its receipt
Citations to the clause and page on every output. If you can't verify it, you can't rely on it — and our customers' auditors agree.
Small team, serious infrastructure
We're deliberately lean — and certified to standards most companies our size never attempt, because the customers we serve accept nothing less.
We have administered these contracts ourselves.
