One sector. One product.
ARK360 builds BTR OS, the AI-native build-to-rent platform. Twenty years of property and construction delivery, a Microsoft-first stack, and governance held from the first line of code.
Amplify human excellence, so that what we build leaves the world better than we found it.
A new asset class needs new operating software.
Australia's build-to-rent sector has moved from a niche bet to a core asset class, and 80 per cent of the pipeline is run by dedicated operators. We watched the buildings arrive while the teams inside them were still running on repurposed strata and agency tools.
As the sector consolidates, operational maturity is what separates the platforms that scale from the ones that stall. Operations carry the resident relationship and the compliance burden, and today they are the least well served. That is the gap BTR OS was built for.
How we are changing build-to-rent operations.
Three commitments run through every module we ship.
One record
Everything that happens in a building lands on one resident record and one audit trail. When compliance, an auditor or an owner asks, the answer is a query, not a project.
Governed AI
Sentinel works the same role-scoped tools as the team, inside the same guardrails, with every action recorded. Autonomy is earned module by module, never assumed.
Resident-first
Residents get one app for entry, visitors, bookings and rent. Operations software only works when the people who live there actually use it.
What we will not compromise on.
Six pillars sit behind every decision, from the roadmap to a single door schedule.
Property is the domain
We specialise in property. We know the workflows, the systems and the compliance because we have shipped inside them.
Built for the people inside
The resident, the worker, the occupant is who the software is for, not the org chart.
Governed and compliant by design
Access control, audit trails and compliance built in from the start, never bolted on.
Less friction, more done
We remove operational friction so teams focus on the work that matters.
Production over prototype
We ship into live property operations and stand behind what runs.
Built to endure
Made to hold up in regulated property and government environments for the long term.
Built by the person who answers the phone.

BTR OS
Live in pilotOne sector, one product. The AI-native build-to-rent platform, live in pilot.
The platforms under everything we ship.
BTR OS is built natively on Microsoft Azure and .NET, with Microsoft Entra identity. ARK360 is a Microsoft AI Cloud Partner in the ISV Success program, with a Microsoft Marketplace offer in progress.
BTR OS runs on Suprema BioStar Air, a cloud-native access platform used worldwide, so operators get proven, biometric-capable hardware with governed software on top, already shipped multi-site.
See it running.
BTR OS runs today on real hardware, in real buildings. A pilot puts it on one of yours.
