WHO WE ARE

The people who run the engagement

Prefraud is a Melbourne consultancy founded in 2026. Engagements are delivered by named people, not an anonymous brand, and their public profiles are below.

FOUNDER

Mackenzie Henderson

Mack leads engagement design and delivery. He agrees written scope with legal and risk, models the refund and returns pathways most exposed to pressure, runs the approved scenarios, and writes the evidence report the client acts on.

His background spans security research and frontline retail operations, including point of sale, returns handling and staff training. Most refund fraud lands at that counter, and the controls that fail are the ones written without it in mind.

CHIEF ACQUISITION OFFICER

William Nguyen

William is the first point of contact for new engagements. He handles the initial enquiry, the scoping conversation before anything is committed to writing, and the commercial terms that sit around the work.

He leads client acquisition, partnerships and commercial strategy, and stays the named relationship contact so there is one person accountable for it while testing is under way.
