Meet Tamsin Simounds

Committed to Excellence

Scientist by training. Philosopher at heart. On a mission to rewire how we lead, grow, and work.

Tamsin Simounds helps people and organisations grow - on purpose.

For over a decade, Tamsin has coached founders, advised C-suites, and spoken to thousands of leaders across APAC and beyond. Her work sits at the intersection of neuroscience, personal transformation, and culture change. And it’s built for this moment.

As a Masters candidate in Neuroscience and Business, and creator of The Experiment Mindset Method, Tamsin brings the science of self-directed growth into the real world: boardrooms, off-sites, leadership programs, and critical inflection points.

She’s not here to optimise your calendar. She’s here to help you become the kind of leader the future needs: clear, courageous, and deeply connected to your purpose.

The Mission

High Performance Cultures Had Their Day. Now It’s Time for High Personal Growth.

Tamsin is leading a shift away from pressure-based performance models toward sustainable, people-first cultures that actually work.

Backed by neuroscience and built on her Three Levers for Change framework - Psychology, Physiology, and Environment and Experiment Mindset Method, her approach helps organisations evolve without breaking their people in the process.

Her upcoming book with Wiley, will soon be shaping conversations in leadership circles around Australia and beyond.

Known for Her Warmth. Respected for Her Rigor.

Whether on stage, in a coaching session, or facilitating a high-stakes executive offsite, Tamsin brings:

Depth over hype
Actionable tools over jargon
Curiosity over certainty
And always, a human-first lens

Her sessions leave people talking - not just because they’re inspired, but because they’re changed.

A note from Tamsin

I believe growth is the purpose of life, and that workplaces can be the most powerful catalyst for it.

I’m not interested in helping you perform for performance’s sake. I’m here to help you lead with clarity, build cultures that heal instead of harm, and create change that lasts. Starting with yourself.

If you’re ready to lead differently, to grow courageously, and to stop settling for ‘good enough’ in your culture, I’d love to work together.

Let’s create something extraordinary.
