Our team

Amy Materka


Amy is particularly interested in the stories we tell about ourselves and our organisations in moments of transition and change. Her mission is to help people connect more deeply to their work by holding a space where stories can be shared, reflected on and re-made.

She is an expert on organisational transformation with 20 years experience driving human centred transformation efforts in Australia, US, UK and Europe, at companies such as BCG, Qantas, NewsCorp, Siemens and Elsevier.

Amy is a visiting Professor at the Berlin School of Creative Leadership where she teaches “Strategy as Story”. She also serves as a coach on INSEAD executive education programs including “Transforming your Business with AI”, “Building Digital Partnerships & Ecosystems”, and “Design Thinking & Creativity for Business”.

Amy has lived and worked in six different countries, and has recently moved back to Sydney from France with her family.

She holds a Bachelor of Arts (Honours) & Economics, an MBA with Distinction from INSEAD, and has trained in group relations, executive coaching and Vipassana. She held a scholarship at the Australian Institute of Sport in netball, and represented Sydney, Perth, NSW and Australia in competition and training squads. These days her love of movement manifests on the yoga mat, hiking in nature and swimming in the ocean near her home in Newport.

Our Purpose

Why do some people, groups and communities take up their authority and act on what they believe in and others don’t?

Our purpose at Sapling is to continuously study how leadership and followership emerges in relation to the big systemic challenges we face as a society; climate change, inequality and mental health.

Net zero

We actively manage our emissions. Our home office has Solar panels and a battery, we lease an electric car and take buses to travel to local clients, and offset all our flights. We are continue looking at ways in which we can better calculate, and manage our emissions.

Acknowledgement of Country

We acknowledge the Gadigal of the Eora Nation the traditional owners of the land where we work and live. We pay our respects to Elders past, present and emerging. We celebrate the stories, culture and traditions of Aboriginal and Torres Strait Islander Elders of all communities who also work and live on this land.


We don’t hold people captive under some ideal image of leadership. We believe people need to determine for themselves what works and is good in their context.


We are interested in growth more than in knowledge. We seek to integrate increasingly more complex ideas and diverse identities.


Art and beauty shape things that happen. We value beauty as the connection to the natural world and our integral selves. Beauty is the antidote to instrumentalism in organisations.


Authorship is crucial for purpose and vision, which cause things to happen. We create the world we live in and we take ownership of what we create.


We look for meaning and relationships that we can love. Not romantically, but rather as something we can freely commit to and sacrifice for.


We strive to be effective. We look for potent and meaningful ideas and partnerships that we can bring to life.
