What's hard about leadership hasn't changed in 100 years.

Speaking up when it's risky. Holding a room when stakes are high. Building trust when there’s no time to earn it slowly. We've been working with people on these things since 1912. More than 9 million people trained. The principles still work because human nature hasn't changed.

The book that started it all

Still the most widely read book on human behaviour ever written.

How to Win Friends and Influence People has sold more than 30 million copies since 1936. It's been translated into 36 languages. It shaped the way millions of people think about communication, trust and influence. 


We don't bring this up because it's a nice piece of heritage. We bring it up because the methods in that book are the same methods we use in the room today. Refined for nine decades. Tested in every business climate from the Depression to the AI era.

Our heritage

Built on a
belief that's
still working.

Dale Carnegie started in 1912 with one idea: people can change their lives by changing how they think, behave and communicate with others. The development work we deliver inside organisations today still rests on that idea.

What's changed is the world around it. AI has made answers cheap. The capabilities that decide whether organisations perform in 2026 are the human ones: thinking clearly, persuading well, navigating disagreement, bringing people with you. That's the work we've been doing for 114 years and it's why our clients keep coming back.

When dealing with people, remember you are not dealing with creatures of logic, but with creatures of emotion.

— Dale Carnegie
