Portrait of Nick Harvey

Nick Harvey

Co-founder & Principal

Nick is a trusted commercial adviser and business leader with extensive experience leading organisations, advising executives and helping leaders and organisations navigate growth, transformation and complexity.

He is recognised for combining strategic clarity with practical commercial judgement—bringing people together, aligning priorities and helping leaders make confident decisions that deliver measurable results.

Nick’s commercial perspective is grounded in direct business ownership. After returning from the United States, he acquired an underperforming packaging company in 2002, rebuilt the business and sold it in 2008. Since then, he has worked alongside business owners, executives and leadership teams to strengthen strategy, performance, growth and organisational capability.
