Stop the 32% Failure Rate Sinking Your Margins

30 years of building experience meets data-driven systems to improve your profitability.

Building a great project shouldn’t be a battle against hidden costs.

A failed council inspection is more than a program delay; it is a defect, a loud, expensive signal that your systems are failing. With over 45,000 inspections failing first time annually across the industry, these aren't just one-off mistakes; they are a systemic leak in your profit. For every official "Fail," dozens of undocumented defects occur at every stage of the build. These 'micro-leaks' are the hidden costs that truly sink a builder's margin. They are the avoidable costs your financial spreadsheets aren't designed to catch.

By the time you see the loss, it’s already too late

The Hidden Profit levers

My PhD research and 30 years in the field have shown me that fixing inspection problems is only the tip of the iceberg. True profitability comes from understanding what lies beneath. The Profit Builder System provides a data-driven approach to uncover what lies beneath: the profit levers hidden in the systems you already use.

Built for the Site, Not the Office

Time is your most valuable resource, and the last thing you need is more paperwork. The Profit Builder System is designed to be seamless, offering real-time visibility into hidden leaks so you can protect your margins before they disappear.

No complex software-just the data you need to take immediate action. Time is important, and the last thing needed is more paperwork.

The MVP Partnership

I’m looking for 20 New Zealand residential builders to partner with me to help shape this system into a digital platform, with a view to developing the product further.
