GC Index Insights
A powerful business tool to help leadership teams deliver their purpose and strategy with clarity, pace and impact.
The GC Index® brings fresh insight into how your leadership team creates impact and where untapped potential or gaps might sit. It helps you see how each person contributes energy, influence and drive to what matters most. We use it to help senior teams align around purpose, deliver strategy and focus energy where it makes the biggest difference.

What is the GC Index®?
The GC Index® is a data-driven framework that measures how individuals and teams make their best impact at work. It looks beyond role or personality to show how people bring energy to innovation, implementation and influence.
As accredited GC Partners, we use these insights to help leadership teams assess their collective strengths, identify what’s missing and build the right mix for today’s challenges — and tomorrow’s.

How we use the GC Index at Mix Partners
We use GC Index insights as a foundation for deeper conversations about purpose, performance and leadership. It’s often where we start when helping executive teams align around strategy or reset how they lead together.
The GC Index turns abstract ideas into practical action; helping you see how your leadership mix supports your goals today, and what you’ll need as your organisation evolves.
