About HazNode®

The software we wished existed. So we built it.

HazNode® was born inside a working New Zealand occupational hygiene and safety consultancy. We needed one system to run quoting, sampling, lab work and reporting without spreadsheets — and when we couldn't buy it, we built it. Now it's available to every consultancy.

Built by practising occupational hygienists. Trusted by the companies that trust them.

Meet The Founder

Logan Miller

Founder, HazNode® · Consultant

“I spent years running a consultancy out of spreadsheets. HazNode® is the system I always wanted — built by someone who's actually had to run the business, not just the science.”

Logan is a health and safety professional whose career has been spent running the operational and commercial side of high-risk work — not just advising on it. He has led safety across multi-site, multi-discipline operations, managed relationships with regulators and boards, and built and run the kind of consultancy delivery that HazNode® now digitises.

That operator's perspective is the reason HazNode® is built around how a practice actually makes money — quote to fieldwork to report to invoice — rather than around a feature list.

Led health & safety across multi-site operations — from small teams to sites of 1,600 people
Worked for two of New Zealand’s largest privately owned family enterprises
Acted as an expert witness in the High Court, for both defence and prosecution
Advised boards and senior leadership, and delivered on projects from $25k to $75m

Université de Montréal

The statistics, done properly.

HazNode®'s exposure statistics are built on the Bayesian methodology used in Expostats — developed in collaboration with a world leader in the field from the Université de Montréal. Rigorous, peer-respected analysis that hygienists can defend, built directly into the platform instead of bolted on after the fact.

Security & Trust

Your data, protected and defensible.

Certification in progress

HazNode® is working toward ISO 27001 and SOC 2 with Scrut — formalising the security practices the platform is already built on.

Encrypted & resilient

Hosted on encrypted, multi-region cloud infrastructure with strict access controls, continuous monitoring and built-in redundancy.

Defensible by design

Strong audit trails and a complete record lineage mean your data stays protected, available, and able to stand up to scrutiny.

Built by consultants. See if it fits yours.
