People behind the platform

Construction software only works when it respects construction reality.

Companion Systems is led by people who understand that reality from different angles, including Matthew Camenzuli and General Manager, Angus Thomson. The broader team is a blend of builders and software engineers, bringing practical site understanding together with technical delivery.

Before becoming General Manager, Angus ran his own successful building business using the Companion Systems suite of products, so his view of ‘what good looks like’ is grounded in lived experience: the pressure of timelines, the volume of decisions, the cost of rework, and the frustration of systems that do not match site reality.

‘When I was running my own building business, the hardest part was not the build. It was the constant follow-up, chasing trades and suppliers, managing delays, staying on top of defects, and keeping pace with compliance,’ says Angus.

‘OnSite Companion took that complexity out by fitting to how we actually worked, then keeping everyone aligned on one clear answer, what needs doing next.

‘With turn-by-turn next steps and offline capability, the job kept moving on site and in the office, without the usual admin wheel-spin,’ he says.

Built to fit your business, not the other way around

Every builder has a different rhythm – different documents, different approval steps, different roles, and different ways of running the site.

‘That’s why we place a big emphasis on customisation and integrations, ensuring all our products are designed to be custom-fit, including permissions, workflows, templates, fields, documents and more,’ explains Matthew Camenzuli.

It’s not set and forget, either. Teams are trained so the system keeps evolving with how the business operates.

This matters because many growing businesses hit the same wall. As projects scale, it becomes harder to stay on top of delays, supplier follow-ups, compliance requirements, and the day-to-day coordination load. Companion Systems exists to reduce that load by making the next steps clear.

A platform for residential, multi-residential and commercial teams

HIA members operate across a wide mix of project types, and the operational pressures are different depending on the work you do. The Companion System suite of products is built to support residential builders, multi-res and commercial teams, and suppliers across the construction ecosystem.

Multi-res and more complex delivery models introduce another layer of control challenges, especially around documentation, dwellings and horizontal workflows. If you have ever had the headache of figuring out which documents belong to which dwelling, you already know why embedded document management and structured workflows matter.

Co‑developed with builders, not just for them

Many vendors claim to value user feedback, yet their roadmaps remain largely internal. In contrast, Companion Systems hosts an annual user group event where users have the opportunity to voice their desired developments.

This direct input from users, combined with insights from multi-generational builders and software engineers, ensures the product stays aligned with local regulations, market shifts, and real-world site challenges across Australia and New Zealand.

Estimator Companion, coming soon

Companion Systems is excited to announce Estimator Companion is coming soon, a new product designed to streamline estimating for residential and commercial builders.

Developed by builders and industry experts with over 30 years’ experience, Estimator Companion offers an intuitive, adaptive estimating platform that meets the unique needs of Australian construction businesses.

This product empowers builders to increase efficiency, reduce errors, and improve workflow by offering seamless integration with existing Companion Systems tools like OnSite Companion and accounting software such as Xero and MYOB.

Key features include:

• intuitive templates for every build type to support consistent estimating workflows
• fully customisable purchase orders and reports to match the way each business operates
• seamless integration with Xero, MYOB and OnSite Companion, helping reduce duplicate data entry and manual workarounds.

The result? Less time spent on manual data entry and more time focusing on what really matters - getting the job done right the first time.
