Meet the Team

Simonne Liley - Founder

In Simonne’s 25 years in industry, she has seen her fair share of industry legends “bleed out” with excessive empathy and burn out with excessive hours.

Simonne is passionate about working with her industry to change that. One of the many learnings she had from recent years is how important resilience and self-leadership is, so we can lead with calm, deliberate confidence; without sacrificing self or profit.

A love of people and behavioural processes, Simonne recognised that increasing revenue is not the only part of the wealth equation.

Extensive studies in Positive Psychology, Mental Fitness, Facilitation, Behavioural Profiling, a Certified Master Coach Ultimate, Master NLP Practitioner, and Time Line Therapist, Simonne is passionate in identifying, understanding and removing disempowering patterns that get in the way of our full potential.

“Fulfilment and success are an inside job.”

Whilst an introvert, Simonne has spoken at multiple industry, women and coaching events, in NZ and offshore.


Passionately addressing our need to address our internal environment.

In 2023 Simonne was immensely humbled to be a winner in The Ignition Top 50 Women in Accounting award, one of only two New Zealanders.

Why choose Simonne as your business guide? Being in business can be a lonely and challenging space. Simonne understands that to get accelerated results in business we need to address the whole. The business and how you show up in it. What makes you do what you do, think how you think, what makes you, you!

She doesn’t just get you the bog standard results of increase in your bottom line or more time for you in your working week. She works with you to unpack the deeper desires that you want to achieve AND strategies on how to make it happen.
