Client References and Sales Training Cases

What does a sales training really deliver? Read it at 52 organisations

You have probably seen a training that was forgotten after two weeks. A good day, lots of energy, and then everything went back to the way it always was. Who wants another training that only delivers a nice day?

That is why this page shows no promises, but organisations. For each case, you read what I trained, why and what it delivers. From hosting company to fashion store, from aerospace components to hair salon. Since 2003, I have trained more than 2,000 sales professionals from more than 400 organisations. In 2025, I was named best sales trainer of the Netherlands, and my trainings score an average of 9.6 from more than 900 reviews.

For directors and sales managers

You are not investing in a training day. You are investing in revenue, conversion and a team that takes control without you. What does it cost you today when your team leaves closable deals on the table?

One sales language across the team: inside sales, field sales and management work with the same method: 12 sales techniques and 11 scientific topics.
Tailored from the intake: the training matches your market, your product and your customer. No standard programme.
Measurable return: the Sales Performance Scan measures your team's sales knowledge before the training and one month after. You see in black and white what your investment delivers.
Lasting results: the AI Sales e-learning keeps the method alive after the training.

For the professional looking for a training

Looking for a training for yourself? Then you do not want theory, but techniques you can apply tomorrow in your own conversations. You do not want to leave with a binder, but with confidence. Right?

In a classroom training, you work in a group of up to 8 participants, with your own real-life situations. Prefer a fully personal approach? Then individual 1-on-1 coaching is the fastest route. English-language trainings are delivered by Kyle Campbell, native English trainer, using the same method.

Critical questions, honest answers

We have had a sales training before. It did not stick.
I hear that often. A single day without follow-up rarely changes behaviour. That is why I work with a closed system: intake, tailored training, e-learning afterwards and a measurement one month later. That way, you see whether it sticks.

Our market is different.
That is true, and that is why every training starts with an intake. This page shows organisations from five sectors, from aerospace to retail. The method is the same, the application is yours.

My salespeople are experienced.
Experienced salespeople often have habits that once worked. The method makes conscious what now happens by feel, and that makes it repeatable. Who would not want their best conversation to become the standard?

What does it cost?
A classroom training costs €695 per person. An in-company training costs €1,875 for up to 6 participants and €3,750 for up to 12 participants, excluding VAT and travel costs. See all prices of my sales trainings.

How do I know it works?
Measure it. The Sales Performance Scan measures the same 35 practical questions before and one month after the training. The difference is your result.

What does it deliver for organisations?

Control in every conversation: salespeople who steer the conversation instead of waiting.
One sales language in the team: inside sales, field sales and management work with the same method.
More closable deals closed: conversations that deliberately work towards a decision, without pressure and without discounts.
