    Leadership is never greater than the quality of thinking

    Think about it

    How you approach leadership strategy, understanding complexity, problem-solving and designing solutions is first thought and then action.

    Your Grey Matter, therefore, becomes a vital tool to continually refine to produce high-quality thinking and actions. > Thinking newsletter fills your Grey Matter to do just that.

    What's Inside

    It's a resource. You will be introduced to a vast reservoir of practice-based thinking that integrates the best of three worlds - first principle science, academic rigour and real-world commercial application.


    First Principle thinking. Pseudoscience, textbook MBA models and armchair philosophy have diminishing returns in 4IR. *We guide you by focusing on frameworks, models and skill set necessary for effective next-generation leadership. Focused intention. We raise your awareness about approaches to understand complexity, solving difficult problems, and designing/ implementing solutions. When you're confused think of this as your 'Prof.' who's giving you ‘bottom line' clarity.

    Respect for context. Our readers are from every corner of the globe, like China, Europe, Middle East, UK, South Africa, USA and Russia. In addition from across all sectors - finance, automotive, sport, FINTECH, tourism, government, health care, etc. All this might seem confusing, which is why our basic starting point is the detail of socio-cultural 'DNA'.


    Functional. Practice-based, versatile and applicable. Simply add context, stir and apply.
