Who we are?

Our constantly growing network of experienced and high-profile professionals share the same exciting view of a prosperous future in which transformational developments innovate the way we live and do business. As seasoned business managers with recognised leadership expertise, we are able to engage with you as consultants, trainers, interim managers and/or entrepreneurs, which is why we call ourselves developers rather than consultants or advisers. We think and act holistically. Looking at your strategy, operations and leadership through the systems lens, we are aware of their mission-critical interdependencies from our experience. As we cover at least two of these three domains, we call ourselves developers of people, business and enterprises to summarise the various roles we can adopt.

Our collective experience is based upon multiple assignments with and positions in everything from innovative start-ups, SMEs and family-owned businesses to globally acting multinational corporations. Our core values based on trust foster our commitment to create value. We are dedicated to discovering, designing and developing, driven by our client’s success in becoming fit for the future. We are at your service if you want to exploit your organisation’s full potential in becoming fit for the future, no matter where we start.

What drives us?

We believe in a global society which will continue to flourish in a sustainable manner. Our engagement with individuals and organisations to develop value in terms of people, planet and profit is our commitment to a prosperous future. Even if system change requires collective societal action, the role of corporates is predominant to make this possible, with a focus on catalysing business organisations to transform for future fitness. As insights, knowledge, experience and wisdom constantly grow in the marketplace , we are committed to continuously integrating, amending and developing our approach to constantly provide best value to our clients. We are keen on sharing our own practices with all our clients and partners.

How we do this?

Whether our client’s immediate need or challenge concerns projects and/or programmes for people and leadership development, operational efficiency (house- in-order programme), building innovation capabilities, or defining masterplans for mid- to long-term strategic change, we build our work on a science-based system understanding that is applicable for business.

The B Corp Declaration (extract)

As B Corporations and leaders of this emerging economy, we believe:

  • That we must be the change we seek in the world.
  • That all business ought to be conducted as people and place mattered.
  • That, through their products, practices, and profits, businesses should aspire to do no harm and benefit all.
  • To do so requires that we act with the understanding that we are each dependent upon another and thus responsible for each other and future generations.
