MEET THE TEAM
We’re a close-knit team of thinkers, doers and change-makers who believe in better — better ways of working, better outcomes for clients and a better experience for the people delivering them.
WE’RE HERE TO DO CONSULTING DIFFERENTLY
Our core team brings together seasoned transformation leaders, strategists, technologists, and change experts — all united by a belief that there’s a better way to do consulting.
We’re grounded, curious, collaborative and here to make a real difference. Many of us have been client-side, driving change in complex organisations and overcoming the very challenges our clients face today. We show up with humility, challenge when it counts, and genuinely care about the people we work with.
Around us is The Change Society: a curated network of over 1,000 practitioners with deep domain expertise and real delivery experience — ready to be mobilised around your most strategic missions.
Come and say hello to just some of the friendly faces in Team Orange.
