More than 80 major corporates, in USA, Canada and Europe have taken up Effective Intelligence on an organisational scale with in-house licensing of Effective Intelligence. They have undertaken system-wide development with their own staff to spread the know-how to priority areas of their business. An even greater number of corporates, however, call in professional Effective Intelligence Associates to lead programmes to meet specific goals for groups. And many businesses also draw on these consultants for coaching key personnel in Effective Intelligence. The combination of in-house licensees and external Associates is the way favoured by many clients. This joins the benefits of experienced Effective Intelligence Associates with the in-house knowledge of the client business.

Intelligence is essential but not sufficient without effectiveness: head and heart in symbiosis. Outstanding contributors in business, from the highest levels downward, not only think well but get things done. They make more wise choices than others, and they get people to adopt their decisions and take them through to completion. Now that innovation has to be everywhere, routine experience is no longer enough to do the job. Everyone has to think, and from first principles when the task is new to them. Businesses, some of the best in the world, find that Effective Intelligence is the most practical skill-set to scale-up their people's thinking capabilities.
