Our trainings yield ten times the amount of your investment.

Our motto: all trainings must pay for itself. Tenfold!

Curious how we do it ?

Significantly better results

Why is that important ?

As a buyer, you contribute significantly to the profitability of your company

The reality is that around 50 – 80% of the sales value is purchased! So the question is: do you get the most out of it? Are you a buyer that delivers a maximum return for his or her organisation? And, more importantly, do you get the most out of yourself as a buyer? Do you still really like your job? Or do you need a challenge? Do you want to have more tools and techniques at your disposal? So both you and your organisation can benefit?

‘Making other people successful gives me a tremendous amount of energy.’

“I think that as a human being, you need to keep developing. Your entire life. It’s good for you. Good for the people around you. And good for the company you work for. At the same time, I see buyers in most organisations becoming stagnant. All this despite the pressure on them increasing as they work in procurement for a longer period of time. And that is exactly where my passion for training can help you: to bring both procurement and buyer to a higher level.”
