Validated in two weeks, built in five months, live for a ten-year liability window.
Handover+ is a digital handover record for residential builders. Every product, warranty, certificate and maintenance schedule is captured when a home changes hands and stays with the property for its lifetime.
Only figures already published for this project. Live since 2026, with the legislative change as the deadline.

Defect liability window the record now covers, up from six months.
The same path every Mayfly project follows: the expertise a company already has, where it stopped scaling, and what was found and built.
01The expertiseWhat the company had
A residential building group in Victoria knew exactly what goes into a home: the products, the warranties, the certificates, the maintenance each one needs.
That knowledge existed. It sat in email threads and glovebox folders.
02The limitWhere it stopped scaling
Victorian builders now carry defect liability for ten years, up from six months. Most have no evidence trail to match.
A warranty that cannot be produced on demand is a liability the builder carries alone, and the paperwork that leaves with the owner is gone for good.
03Find the leverageIdentify · Validate
Before anything was built, Mayfly mapped what a builder has to show across the liability window, and designed the record around that.
The legislative change set a fixed deadline, so validation took two weeks and the build five months.
04Build itDesign · Build · Launch
Handover+ captures every product, warranty, certificate and maintenance schedule at handover.
Owners receive a maintenance plan. Builders receive an evidence pack they can produce on demand. It launched with the building group so it could prove itself on real handovers.
Your company has spent years building expertise. Mayfly turns it into something the whole business can scale.
