Jack Martin Leith

In his 20s, Jack embarked on an inquiry to discover how the new comes into being, and how this changes into that, beyond prevailing models and methods. The inquiry continues.

For more than three decades, Jack has been helping organisations think differently about innovation, change and problem solving work, and has supported them as they deploy new models and methods that generate abundant value for customers or users and other stakeholders.

Multi-stakeholder co-creation formed the core of his consulting offering many years before it became mainstream practice.

Jack’s services have been commissioned by global corporates, government bodies and other public sector organisations, social enterprises, arts organisations, charities, startups and consulting firms (top tier and boutique).

Past clients include ABN Amro Bank, Diageo, Dogs Trust, European Commission, GlaxoSmithKline, Kearney, McCain Foods, NHS and Petroleum Development Oman.

He was closely involved in Shell’s acclaimed GameChanger programme during its formative years.

Paul Levy, Senior Lecturer, School of Business and Law, University of Brighton (view profile), and founder of Rational Madness Theatre Company, FringeReview and consulting firm CATS3000:

“Jack is an innovation consultant who walks the talk. He is constantly innovating his own business activity, its design and aims. He is ‘the person’ to talk to for large group interventions, for whole system change and innovation. I attended a five day Open Space conference that Jack facilitated. It set me on a new path in life. Jack is highly committed and skilled, challenging and truly creative. Jack thinks deeply about innovation and transformation. He has developed a range of propositions about innovation which can lead to new insights on the topic. He understands creativity and innovation and has developed practical ways to develop innovativeness in organisations. Jack’s views tap into the wild and the wonderful as well as the rational. He likes to shake things up, and to help that shaking to happen quickly. He doesn’t mess about! You won’t always find it easy working with Jack because he is one of that rare breed – an authentic agent of change and innovation who is prepared for things to get harder before they get easier.”

Angus Jenkinson
Angus Jenkinson, formerly Professor of Integrated Marketing at University of Bedfordshire; currently Vice Chair of Overview and Scrutiny Committee at Cotswold District Council:

“I have worked with Jack for more than 20 years. He has one of the most brilliant, penetrating, erudite, and practical minds I know. With his exceptional experience of innovation, large group work and organisation development, he is a terrific partner for clients and consultancies with major projects.”

Math Kohnen
Dr Math Kohnen, formerly a member of the Group Strategy unit at Shell plc and a vice president at Shell GameChanger.

“Jack worked with the Shell GameChanger team to design and deliver innovation workshops in Rijswijk, Netherlands (with a large group of first assignees); in Moscow, Russia (with scientists from a range of scientific institutions); in Trondheim, Norway (with academics from Norwegian University of Science and Technology); and in Ascot, UK (with academics from Imperial College and Wageningen University, along with members of Shell’s Water to Value team). His understanding of the issues, passion for innovation and down-to-earth approach made a valuable contribution to GameChanger.”

Tom Bourner
Tom Bourner, Emeritus Professor of Personal and Professional Development, University of Brighton, UK:

“I’ve known Jack since 1995 when he taught the Creative Problem Solving module of the MA in Managing Change at the University of Brighton1.

His workshops were very well received by the participants (most of them managers in the private and public sectors), who appreciated Jack’s encyclopaedic knowledge of the field of creativity, innovation and change, and his provocative yet supportive style of facilitation.

We brought Jack into the team because of his special expertise in the field and it would be true to say that the rest of the staff team learned a great deal from Jack about creative problem-solving and how to develop it in managers.”

1. Jack ran the workshop annually for seven years.

Rohit Talwar, CEO, Fast Future:

“Jack is a living example of innovation, creativity and constant reinvention. His capacity for original thought, creative process design and in-depth research is awe-inspiring.”
