The missing data point in most hiring decisions.
Most organisations already have personality and competence data. What they don't have is Energy for Impact data. The GC Index changes that.
What the GC Index measures
The GC Index is the world's first Organimetric — a tool built specifically around organisational impact, not personality. It identifies five natural proclivities: the distinct ways in which a person is energised to contribute to a role, a team, or an organisation.
This is different from a personality test. It is different from a competence assessment. It measures something most hiring processes never ask about: how someone is naturally wired to make an impact.
Game Changer
Generates original ideas and transformational possibilities. Drives change. Sees what could be, not just what is.
Strategist
Makes sense of complexity, sets direction, and focuses on long-term goals. The bigger picture thinker.
Implementer
Turns ideas into reality. Gets things done. Pragmatic, outcome-focused, and reliable under pressure.
Polisher
Drives excellence and continuous improvement. Raises standards. Strives for the best possible output.
Play Maker
Builds collaboration, strengthens relationships, and creates the conditions for collective performance.
None is superior to the others. The value is in understanding the combination — and whether it matches what the role, team, or organisation actually needs.
Most hiring failures are not capability failures.
They are fit failures — a mismatch between a person's natural energy and the conditions of the role or environment they have been placed in.
The GC Index gives us a language for this. Before a search brief is written, we can define the Energy for Impact the role actually needs. During assessment, we can see whether a candidate's natural energy matches that need — not just whether their CV suggests they can do the job.
“The problem with most hiring is that we measure what people have done. We rarely measure what energises them to do it.”
