Why Leaders Choose Patient Zero


Adam Skinner

COO, CitrusAd

The engagement with Patient Zero enabled us to get from delivering one product line to delivering eight product lines concurrently in the space of 6–12 months - even to this day, we’re still using the Way of Working that Patient Zero is built on.

Marcus Sweeny

CIO, National Transport Insurance

Patient Zero helped keep our business stakeholders consulted and accountable for scope and feature-based decisions, making my life easier when it came to managing expectations around scope and timelines. We love the engagement style because NTI was in complete control over the contents of each sprint.

Alice Evans

CEO, True Relationships & Reproductive Health

Patient Zero consultants partnered with True Relationships & Reproductive Health to guide the implementation of a new EMR system and enabled an extremely positive change for the business in just four months.

Jeff Peters

Manager, Brisbane Catholic Education

The Governance practices that Patient Zero employs is one of the things which initially attracted me to work with Patient Zero. It really puts BCE into the driver's seat and gives us back control.
