What Our Clients Have To Say…

 “The game-changing challenge was a fantastic way to get new input and perspectives to our challenge from a diverse group of individuals. The radical process students went through to understand the challenge and come up with ideas that was really interesting – this has helped us question ourselves and look at things from a very different perspective.”
Peter Markussen Senior Manager at Energinet
“The game-changing talent competition worked perfectly. By changing the value chain from ‘Producer to Consumer’ to ‘Consumer to Producer’ students got to understand what XTN is very quickly. Structuring the challenge in this way meant they came up with some incredibly creative solutions as to how we can reach the consumers, which we will be exploring.”
Bjørn Bekkevold Founder & CEO at XTN Group Holding
“The GC Index® framework has lifted the team at Leica Geosystems to the next level – it’s given the team the skills, insight and confidence to step up and look for ways to drive growth”
Mark Concannon Executive Vice President at Hexagon Geosystems

Eleanor Allen CEO, Water for People

Mike Ksenyak Water For People
“The GC Index quickly enabled us to understand and communicate how each member of our team could best contribute and make an impact in the process of transformational change.”
Pascal Viginier Group CIO, Orange

Sietske Jacobs Programme Manager, Synergy Initiate!

HR Change Management Manager Italian global bank
“We see The GC Index as our competitive advantage”
COO Global Project Management Consultancy
“My boss was amazing – she put me forward to work on interesting projects and knew exactly where I could add value. She gave me the freedom to work how I wanted and didn’t stifle me with unnecessary questions.”
Game Changer Professional Services Partnership
“They said they wanted someone who was creative and could drive innovation. I quickly realised this was not the case – the board just wanted us to do as we were told. But this was having no impact so I had to leave.”
Director of a small business
“We didn’t have any hard and fast rules in our family. The only rules we had were to have good manners and be considerate.”
Game Changer. Local Government
“I lost heart and felt claustrophobic, so I left corporate life and set up on my own. There was too much red tape, too many barriers and too many people ready to dismiss my ideas without listening to them.”
Game Changer & Entrepreneur
“I have always been called ‘disruptive’ from school through to my working life. I find the ‘disruptive’ moniker very negative and not something I can relate to. This Game Changer movement has answered many questions that I have wrestled with about myself and how I can impact a team or organisation.”
Game Changer Telecoms Sector
“Being a Game Changer can be a lonely place. I often felt out of place – like I was being judged. Quite often it felt like colleagues had formed an opinion of me before they’d even met me.”
Marketing Executive
“Honestly – I feel less of an idiot after reading both reports. I have genuinely been frustrated with my ‘skill set’ for as long as I can remember – I have always found it impossible to explain how I feel to myself or others. This report makes me feel like I do have a role.”

The GC Index is a valuable tool. We have used a number of other assessment tools but the GC Index offers something unique and it is easy to apply in the workplace.

Jo Lewis Talent & Transformation Manager at TM Forum
“Out of any assessment I have ever done, this is the one I feel is the MOST like I actually am….”
Careers Advisor
“I was feeling exhausted and disillusioned at work but The GC Index has given me the tools to take charge of my own game and empowered me to start shaping the future career I want, rather than the one I have fallen into. It’s given me the confidence to stop trying to be something I’m not and to start focusing on my strengths.”
Marketing Manager
